The ultimate SEO glossary: 450+ SEO terms and phrases with easy to understand explanations

Seeing that our SEO tool Morningscore is used by both SEO experts and SEO novices, we decided to give a helping hand to the latter and make an SEO glossary with a comprehensive list of SEO terms and simple explanations.

Being a beginner is nothing to be ashamed of and here you will have a shortcut to everything you need to know to navigate our tool like a pro.

With more than 450 SEO related terms this is the most extensive search engine optimization glossary you will find anywhere.

 

SEO terms starting with A

Absolute URL (Absolute link, Absolute path)

A link used for internal linking. It shows the absolute (or full) path to a file, HTML page, image or anything else you might want to link to within your website. This link is used as a part of the anchor tag and consists of a protocol, a domain name, possibly a subdirectory and the name of the file, document, HTML page, image or something else.

Example of an anchor tag using an absolute path:

<a href=”https://www.seo.com/blog/seo-glossary”>SEO glossary</a>

There are two types of paths used in internal linking – one being the absolute and the other relative. There is, however, no indication that one is more beneficial than the other in terms of SEO.

Algorithm update (Google algorithm update)

Any change to Google’s search algorithms or ranking system. This includes new rules or adjustments to rules already in place. There are frequent small updates that go unnoticed, but there are several major updates in a year that can have a big impact on your rank.

Major updates in the past few years include Panda, Penguin, Pirate, Hummingbird, Pigeon, Mobile Friendly, RankBrain, Possum and Fred.

Algorithmic penalty

The process of your website being suppressed in the SERPs reducing the search rank of your keywords. They are hard to notice unless you keep an eye on any significant drops in your website traffic. The only way to get rid of them is to try to find any issues that might not follow Google’s guidelines and fix them.

Alt tag (Alt attribute)

The alt tag is inserted within the image tag in HTML and used to specify alternate text for an image.  Including a description of the image so screen readers and search engines can get an idea of what is on it is considered a good practice for accessibility and improving content relevance.

By using keywords in your image alternate text, you can optimize them for Google’s image search service.

Anchor text

Anchor text is the clickable text in a hyperlink. In terms of SEO, it is best to use natural language and avoid exact match, overly spammy and keyword rich text when linking to other sites.

Authority site

A site trusted by the user, its industry and industry experts. These sites both publish trustworthy information and link to trustworthy sites, getting a reputation of a high quality, knowledgeable website.

B

Backlink (Inbound link, Incoming link, Citation, External link)

A backlink is created when some other website is linking to your website. In essence, it is a “vote of confidence”, a citation that shows that this other website points to you as a valuable and relevant source.

An effective link has high link authority and high link relevance.

The number of backlinks to a specific website is one of the most important factors when determining its page rank.

You can find more on backlinks in this article.

Baidu

The most popular search engine in China with a Chinese market share of 69.54%  (the next in line are Shenma and Sogou) and a market share of 1.37% worldwide. Baidu offers almost the same services as Google.

Bait and switch (Code swapping)

This SEO phrase refers to a black hat SEO technique where you use certain content on a webpage to rank high in the SERPs. Then, after you are satisfied with the rank, the content of the webpage is swapped out with something else (content which usually wouldn’t be able to get a good rank).

Banner blindness

A well-known phenomenon that describes people’s tendency to ignore elements on web pages that they believe to be advertisements. Ads are considered interruptive and pointless by the users and they filter it out while skimming the page looking for anything of importance.

Bing

A search engine owned by Microsoft with a market share of 3.18% worldwide. According to research 85% of Bing users live in the USA, 87% of the users use it because of Internet Explorer, they are for the most part 35+, less tech-savvy and are more likely to have children. Also, according to some statistics Bing users spend 25% more than users on other search engines.

SEO glossary definition of Black hat SEO

Black hat SEO

Black hat SEO tries to improve page rankings by using tactics which are against search engine guidelines. These tactics create content that is meant to manipulate the search engine and tends to ignore the human audience and their experience. They include keyword stuffing, cloaking, using paid links, doorway pages, over-optimization, hidden text, bait and switch and much more.

Blog commenting

Blog commenting was a very popular link building tactic where you find a blog article that is relevant to your niche and leave a comment with a link.

Nowadays this tactic is cause for debate. Since it was over abused and people massively spammed blog articles leaving links and irrelevant comments everywhere, comment sections now apply a nofollow to links. Google also put a stop to this practice by penalizing links from irrelevant websites and by reducing the link equity passed on by pages that contain massive amounts of links.

As you can see, this tactic can hurt you more than help you. That being said, there are still cases where this is appropriate. Leaving a valuable comment in a blog article can help you build relationships in your niche and result in guest posting opportunities. You might not get link equity, but what you can expect is traffic increase.

Bounce rate

A metric that shows how many visitors came to your website and then left immediately after without performing any actions or browsing any of your other pages. A rule of thumb is the lower bounce rate the better. Having a high bounce rate (over 70%) is a cause for concern and can be caused by many different issues like slow page load, low-quality content, unresponsive landing page, using too many ads, your visitors not finding your page relevant for the keywords they used etc.

Branded keywords (Brand keyword, Brand term)

They are keywords and phrases that include your company or brand name and variations of it. There is ample debate over using branded keywords in your search marketing. SEOs usually argue that there is no need to spend money to rank on these keywords as using SEO intelligently will have you rank high in the organic search results.

 

Brand mention link building

This is a link building tactic that includes you searching for web pages that mention your brand, service, product or personal name, without linking to you. You then reach out to these websites (or those that are relevant and have a decent domain authority to be precise) and have them add a backlink. This is a tactic that has a high return on investment as the chance of the website you are contacting giving you a backlink is very high.

You can use Google Alerts to track any mention of your brand, service or product.

Breadcrumb navigation (Breadcrumb trail)

A type of secondary navigation that helps the user figure out their location on your website. Links appear horizontally providing a link to each previous page on the website.

Example: Home>men>shoes>boots

It is beneficial for both user experience and crawling, as it provides an improved internal link structure for large sites.

They can also be displayed in the SERPs instead of the usual site URL. This creates links that are readable and user-friendly. You can set this up with the Yoast plugin if you are using a WordPress website

Broad match keyword

A keyword matching option in Google Ads. When using broad match for a keyword, your ad will appear for searches containing that keyword or a similar one. This includes phrases, singular or plural forms, misspellings, synonyms, stemmings, and related searches.

Broken link (Dead link)

Basically, a link that doesn’t work. This can be due to an improper URL or a deleted linked page and commonly happens when a page is moved or renamed. It can negatively impact your SEO and reduce your search engine rankings as it can stop crawlers from indexing your website.

terms beginning with C

Call to action (CTA)

An SEO term that refers to a website trigger (usually a button) designed to get an immediate response from a website visitor. These triggers usually use commanding words that are meant to persuade the visitors to perform a certain act like Buy, Register, Write Now, Call, Sign Up.

Having a clear call to action on your landing page improves SEO as it will help your visitors determine what their next step is increasing their time spent on the website and reducing bounce rates.

Canonical URL (Canonical tag)

If you happen to have duplicate content on your website, search engines will not know which one to show in their results. This is why you need to pick one as the original and set a canonical URL on all the other pages pointing to the original. This you do by using a canonical tag (rel=”canonical”) in a piece of code that looks like this <link rel=”canonical” href=”www.seoglossary.com” /> in each one of the copy pages. As far as the search engine is concerned, this merges all the pages into one.

Cascading Style Sheets (CSS)

CSS is a language that defines the look of the HTML document. Every website has one or more CSS files where each element is determined in size, color, layout etc. Here is where we can set up interactivity, animations, responsiveness, font style and more.

Churn and burn SEO (Rank n’ bank)

A Black hat SEO strategy where you mass spam a website with unnatural links getting it to rank high in a very short time. The website will get penalized eventually, after which the owner deletes it, but until then the website earns revenue.

Click through rate (CTR)

A metric showing the percentage of people clicking on your ad/website after it has been displayed in the SERPs. It is calculated by dividing the number of clicks by the number of impressions.

Clickbait

A link that is meant to entice the user to click on it. These links either use anchor text or headline tags that are playing on the user’s curiosity. Using words and phrases like incredible, amazing, ultimate, “must see” and “you won’t believe”, these links have a chance of increasing their CTR. Using clickbait might increase the traffic to your website but think it through first to make sure it is appropriate for your particular niche.

Competitor analysis

Evaluating the competitors that rank for the same keywords you do or belong to the same niche. A competitor analysis will help you find out which tactics work in your niche and which areas you should prioritize.

It is a very useful method for:

  • discovering keywords that you could use
  • discovering new backlink opportunities
  • getting content ideas
  • getting ideas for optimizing your search result title and description

Content

Content is all the information available on a website. It includes text, images, videos, and animations. In terms of SEO, content is a major factor in attracting traffic and influencing user experience.

Content Management System (CMS)

A CMS is a dynamic website where multiple users can edit, update and maintain the content. They are simple to learn and easy to set up. One of the most popular examples of a CMS is WordPress.

In the term of SEO, it is a bit of a trade-off – a website can be set up in a matter of minutes using templates, but you do not have any control over the code. So once the template is in use, you will not be able to make any changes. On the other hand, this is ideal for people that do not have a desire to deal with code. There are plenty of SEO plugins you can use to help with SEO activities.

Content marketing

A marketing method that focuses on the creation and sharing of high quality, valuable online information (in the form of video, audio or text). The purpose is to draw interest and be perceived as a credible source, so you gain more visibility and increase brand awareness.

Start working on your content marketing by using this step-by-step guide.

Content spinning (Article spinning)

A cheap SEO technique where the same article is rewritten, using synonyms or by changing the word order in the sentence. In this way, many articles are created in hopes Google won’t flag them as duplicates. These articles are them posted all over the web and link back to the original. It is a risky black hat SEO practice now done with various software.

As a disclaimer, writers often spin content in their articles to reduce the similarity ratio, but if this is done for only a small portion of your content and you are only posting it once, you have nothing to worry about.

Content syndication (Article syndication, Syndicated content)

A method where content is republished on another site, so we can reach new audiences, increase traffic and build links. This method does, however, fall in the area of duplicate content, meaning that the other site could very likely rank better than you on your own post if it has more authority. It is nonetheless a minimal effort and possibly high benefit tactic, where you should weigh all the pros and cons before implementation.

Conversion

An act of getting the user to perform the desired action. As an example, this occurs every time a website visitor signs up, downloads your e-book, follows a link from your email or interacts with our CTA.

Conversion rate

A percentage of users that completed the desired goal (made a conversion) out of all the users that have seen your ad/website/e-mail/CTA that was intended for the purpose of visitor conversion.

Conversion rate optimization (CRO)

Using various tactics to increase the percentage of website visitors that convert to customers.

SEO and CRO go hand in hand and ideally complement each other. SEO is meant to drive traffic to the website and CRO tactics are meant to convert and ensure that the website generates revenue. Insights and data from your CRO should be also used to find issues and do SEO.

Copied content

Copied content is content that has been copy-pasted from another source. Sometimes they are just chunks of content and other times whole pages have been chopped up and then pasted together creating something seemingly new. Some words can be replaced with synonyms, or one word can be replaced with another throughout the text using the “find and replace” function. This is a riskier version of duplicate content as it can have the purpose of misleading the search engines and can be a cause of a red flag.

Cornerstone SEO term in SEO glossary

Cornerstone content

The most important, extensive articles on your website. They are high quality, easy to read and cover everything that is important in a specific topic. They are usually hub articles that are at the center of your link structure linking and linked to many of your web pages.

If you are using a WordPress website, you can mark a post as cornerstone content with the Yoast plugin.

Cost per acquisition (CPA, Cost per action, Pay per acquisition, Pay per action)

An online pricing model where you pay when a certain action is performed by a user. The example of an acquisition can include a sale, download, sign up, visit your site or something else.

Cost per click (CPC, Pay Per Click, PPC)

A payment method used by Google Ads where the advertisement price is based on the number of clicks the ad gets.

Cost per thousand impressions (CPM, Cost per mille)

A pricing model used by Google Ads where you pay for every one thousand times your ad has been displayed.

Crawl (Crawling)

The process performed by the search engine crawlers where the complete content/code of a website is analyzed. In simplified terms, this happens by the crawler following all internal and external links.

Crawlability

Crawlability refers to the process of enabling the crawlers to easily navigate, understand and efficiently find content and index your website. Site crawlability can be improved by creating an XML and image sitemap, avoiding orphan pages by efficient internal linking, optimizing site speed, images and video and the proper use of redirects.

Crawler (Bot, Spider, Web crawler, Googlebot)

An algorithm used to scan and analyze websites in order to rank and index them.

Crawl budget

Made up of crawl rate and crawl demand, the crawl budget describes the number of your website URLs that Google will crawl. This does not affect small websites. Larger websites should, however, take this into consideration as pages with stale content that are found somewhere low in your link hierarchy (and especially if your website is not rather popular or healthy) will possibly be overlooked.

Crawl depth

Crawl depth is the extent to which the search engine indexes a website. You can check this by testing your page depth, meaning see how many clicks you need to reach a page starting from the home page. The deeper the page’s location, the harder it will be for it to rank well in the SERPs.

You can reduce this problem by using breadcrumb navigation and internal linking.

Crawl demand

Part of the crawl budget, the crawl demand describes how much importance the search engine places on a specific URL. The deeper the page is in the link structure (more than 4 clicks from the home page for example), the less important it is.

Crawl rate (Crawl rate limit)

Part of the crawl budget, this is a technical limitation in the algorithm. A specific number of pages the spider will index that day. This number can be further reduced for your website if Google doesn’t find your website particularly relevant.

Cross-linking

Linking domains owned by the same company or person. It should not be a problem if the websites are topically related and there are not many links. Exact match anchor text and site-wide linking should be avoided to reduce the risk of penalty.

Curated content

Content that we did not create, but we find it very relevant and valuable for our visitors. We then organize and present it to them. The purpose is to create a knowledge-hub that the users will visit frequently to get information on their niche, making you an influencer and an expert.

All SEO terms begining with D

SEO glossary's explanation of analytical data

Data

Distinct pieces of information. In SEO terms it usually points to analytical information used to determine who our visitors are and how they interact with our website.

Dead-end page

If you have a web page without any links it creates a dead-end for your visitors and search engine bots giving them no other choice than to leave the site.

It’s easily avoided by including navigational links in your header/footer, breadcrumbs or links suggesting the next step for the visitor.

De-indexing

The process of removing a web page from the search engine index making it unable to appear in the search engine result pages. This is done by setting the value of the HTML robots meta tag to “noindex”.

The reason why you might want a page de-indexed could be if you have a page that does serve a purpose, but it isn’t ranking. Example of these pages include login and thank you pages.

Deep linking

A method using internal links within the website content. Basically, a deep link is any link from one web page on a website to another web page on the same website. This is used in calls to action or within articles, where a link is used to lead the visitor to a page with more informative content.

It is an important SEO method to spread link equity to your web pages and prolong visitor dwell time and engagement. Also, you will probably have a different, but topically similar set of keywords for each page and linking between them increases overall page relevancy.

Direct traffic

The number of visits to your website where the visitor typed in your exact web address (URL) into the browser.

Disavow links

Not all backlinks are beneficial to your site. Backlinks from unrelated and untrusted sources are considered bad and can get you penalized or in the least have a negative effect on your SEO. This is where Google’s Disavow links tool comes in helping you notify Google that you do not want a certain link from an external site considered when your page is being ranked.

Dofollow link

All links are by default dofollow links, meaning they pass along what we call “link juice” and let crawlers follow them helping a page’s placement in the SERPs.

Domain

The location of a website typically displayed as a domain name or an IP address

Domain name

A domain name is the text that people type in the browser address bar in order to get to a website (www.domainname.com). It is one of the ranking factors in Google’s algorithm, so it is a good idea to make it SEO-friendly.

Domain Authority (DA)

Domain authority shows the relevance of a website for its industry or subject area. It is a metric that measures how well the website will perform in SERPs and how competitive it is compared to other sites in its niche. You can improve yours by, for instance, getting more backlinks from reputable websites.

If you would like to learn more about domain authority, check out this article.

Doorway page (Gateway page, Entry page, Jump page, Bridge page, Portal page)

Created to manipulate the search engine and rank high for particular phrases and keywords while actually having low-quality content. These pages are created for generating revenue from ads and affiliate links.

DuckDuckGo

A search engine that puts an emphasis on user privacy and does not use personalized search results. This means that the users are not being profiled and all the users get the same SE results for a specific search term.

DuckDuckGo has 4.7 million daily users, 50% of them are from the USA and 45% are European.

Duplicate content

Duplicated content is a substantial block of content that appears on more than one web page (within the same domain or across different ones). The problem with duplicate content is that when a search engine bot finds it, it will not be able to determine which domain has more relevance on the subject.

But duplicate content is also a common occurrence within a page. For example, if you have a separate mobile or a local version of your website. In this case, you should pick a page that will be the original and add a piece of code (rel=canonical) to all the others, clearly pointing the search engines to the original version.

Dwell time (Time Spent on Page)

This is the time the visitor spends on your website after clicking on it in the SERPs. Longer is better since it shows that the visitor has found relevant and engaging content. If the dwell time is very short, it is considered a bounce.

Dynamic URL (Dynamic link)

A web address of a web page where content is stored in a database and fetched by a user query. These pages can have only one HTML file, but content will be unique every time the database is queried. This is why the URL changes every time there is a query. These URLs are non-descriptive and make no sense when read since they include link parameters.

Example: www.dynamicurl.com/forums/thread.php?threadid=12345&sort=date

SEO terms starting with E

Expertise-Authority-Trust (E-A-T)

Google’s indicators for page quality that influence ranking. You can increase your E-A-T score by

  • making sure you have ample amounts of content which is updated and edited frequently (kept fresh)
  • having a good user experience
  • have good online and website reputation (be used as a resource by relevant websites)
  • provide access to information on the company and content authors

Editorial link (Natural links, Organic links)

The best backlink you could wish for. They are part of a strong link profile and they are neither paid for or requested. These are links placed within the body of the content and serve the same purpose as a citation, meaning the author of the content has named you as a trustworthy knowledge source on the subject and thinks that their readers will find the link valuable and useful.

Ego-Bait

One of the link building tactics where you use a link to a company/person/ organization in your content, then contact them in hopes they reciprocate with a backlink.

Email outreach explained in the search engine optimization dictonary

Email outreach (Link outreach, Blogger outreach)

An important part of the link building process that consists of finding backlink opportunities and then contacting the site to have them link to one of your web pages.

Backlink opportunities could include:

  • a page with a broken link in an article that matches the topic of one of your web page
  • websites that are relevant to your niche, with a high DA, low amount of outgoing links and a possibility for you to be included in the content body as a relevant resource
  • a website you could write a guest post for
  • a company or person you mentioned in your content
  • a company or person that mentioned you on their website

Exact match anchor text

When the anchor text closely describes the topic of the web page it is linking to, it is considered to be an exact match. In the case of this glossary, the exact match anchor text would be SEO glossary.

Exact match keyword

An SEO phrase that refers to a keyword matching option in Google Ads. Your ad will only appear in the SERPs if the user types in the exact word or phrase in the exact order.

Expert document

An unaffiliated web page with links from many topically related hubs. Expert documents are used by Google’s Hilltop algorithm to determine relevancy. These expert documents can be informationally rich pdfs, e-books or web pages with guides on a certain topic.

SEO terms that start with F

Featured snippet (Rich answer, Direct answer)

When the search term is in the form of a question the first listing in the SERPs might be in the form of a featured snippet. It is displayed in a box with an answer summary and the website link underneath. There is not much we can do to have our website displayed in the featured snippet. Google determines programmatically which website best answers the question and displays it. The one thing we can influence is preventing Google from using our website for the featured snippet by using the nosnippet tag, but it will also block the display of descriptions under your SERP listing.

Freshness (Freshness factor)

One of Google’s ranking signals. New or recently updated content is considered fresh and gets scored by Google. There is, of course, some content that does not need to be updated yesterday to be relevant, where content referring to trends, news, hot topics, updates, and recurring events needs to be refreshed regularly. Google checks trends and spikes in search volume for a keyword before determining how relevant freshness is for it.

Search engine optimization terms that begin with G

Geotargeting

A method of targeting users based on their geographical location. This is usually done because you want to display different content or ads to your visitors depending on where they are.

An SEO term that refers to a link building method where you reach out to websites with a similar topic to your infographic and have them use it to supplement their content in exchange for a backlink to your site.

SEO glossary's terms starting with H

Hit

Each time a file is downloaded from your site is considered a hit. This includes your page’s HTML files, images, videos, graphics, buttons etc. A website page has on average 15 hits.

Homepage

The first (main) page of a website that loads when a visitor types in a web address that only contains the domain name. It is the starting point of the website and the most used page.

Hreflang attribute

Used to mark up pages of a multilingual site. Using this attribute you can make sure that users have the page displayed in the right language based on the language they use in their query.

They can be used to help with the duplicate content. Sometimes you have a website that has the same content for different locations (like UK and USA), with small variations like currency. In this way you let Google know which location or language this webpage is optimized for. Keep in mind though that you will still have to work on link building for each webpage to make sure it has enough authority to be displayed in the desired location.

HTML heading (Heading element, H1-h6 tag)

Heading tags are used in HTML to create structure. They mark titles and subtitles or emphasized text. There are six levels of headings in HTML – H1, H2, H3, H4, H5, and H6. The higher the level, the more important the heading.

They are the simplest way of telling both our reader and the spiders what we believe is the importance hierarchy of the content. Do not use them to define font size, it is better to do this through CSS. You should always keep to the order of the headings, do not use an H4 unless you have an H2 and an H3 also.

Assigning an H1 to a title means that this is the most important element on your page and you should only use one.

HTML sitemap

An HTML sitemap is intended for visitors (unlike the XML sitemap made for search engines).  Made in a form of a bulleted list, it displays links to all the pages on the website. It shows its hierarchy and helps visitors with navigation.

It can be used during the development phase to ensure a good structure that will both spread link juice efficiently and make sense to the visitor navigating the site.

They do not hold the same weight in SEO as XML sitemaps, but they are not completely without SEO value.

The SEO term HTML source code explained in the search engine optimization glossary

HTML source code

HTML (Hypertext Markup Language) is the standard markup language used to create web pages and applications. The HTML source code is the format readable to humans and it is the only stage where we can modify the code before the compiler translates it into what you see in your browser. You can view your source code in any browser (right click + Inspect in Chrome and right click + View Page Source in Firefox). If you wish to modify it, it is recommended to use a plain text or code editor. The bulk of technical SEO is done in the HTML source code.

Hub

A page that contains numerous links to the most relevant and accurate websites in its niche.

Hyperlink (Link)

A link is a clickable (or tapable) text or an image that provides direct access to another page or section of a page, providing easy navigation through the web.

Hypertext Transfer Protocol (HTTP)

The main protocol on the web that lets us show and receive information. In terms of SEO, it is better to use the secure type HTTPS.

Image filename

An image filename is a unique name used to identify an image in a file system. It consists of a name we assign to it ourselves and a file format.

The filename is your chance of explaining the image content to the crawlers. It should:

  •        be readable to humans (don’t name your image IMG_025.jpg)
  •        be as descriptive as possible
  •        but try and keep it short – don’t use stop words like a, the, it, to etc
  •        be somewhat unique (using names like shoe1.jpg, shoe2.jpg, shoe3.jpg will not help you much)
  •        include keywords
  •        use hyphens (dash) instead of underscores

Image title

The image title is an attribute that you can add to the image tag in HTML. In case the image cannot be displayed the title will take its place. Currently, it does not affect your ranking, but it does improve your site’s accessibility.

Image SEO

Refers to optimizing all the images on a website so you can increase content relevance, search engine visibility, and screen reader accessibility.

This you do by:

  •        making sure the file is the right size, so it does not slow down the website
  •        using descriptive file names
  •        adding alt tags with descriptions of what is on the image
  •        creating image sitemaps

Image sitemap

An XML file containing all the images from your website you would like crawled and indexed. This can be a separate file or added to the existing XML sitemap.

Impression

Each time an ad is displayed on the user’s screen or a website is displayed in the SERPs is counted as an impression.

Index

The search engine database that contains data about all the websites the crawler could find. If a website is not included in the index, it will not be displayed in the SERPs. You can easily check if and to what extent your website is indexed by checking the URL in Google’s Search Console. The results displayed will be all the pages on your website that have been indexed.

Indexability

A state of a website where it allows the search engine bots to index its pages for later use in the SERPs. This can be prevented by using the noindex value in the robots meta tag.

Indexing

The process of including a website in the search engine database. The easiest way to get your website indexed is by having others link to you and then waiting for SE bots follow those links.

If you would like to speed up this process, then you can:

  •        upload an XML sitemap that includes the missing page
  •        get backlinks from high DA websites as they get crawled more often
  •        make sure that you are not using a “noindex” value in your HTML robots tag

Infographic (Informational graphic)

A method of presenting information in a visual way meant for easy and quick reading. They are more engaging than a traditional article because the convey complex data in a simple way. This type of content is shared more, takes less time to create and gets more natural links.

Internal link

If the destination of your link is found on your website then it’s an internal link. Internal links connect your website pages and make it easier for the visitor and search bot to navigate through it. It includes not only the navigational links but also links where you suggest to the visitor which page to visit next.

Using the right internal link strategy can help your SEO as you can control your website structure and give certain pages more importance by placing them higher in the hierarchy.

International SEO

International SEO is meant to increase your visibility in other countries and create global growth. You can set up country and language detection and display appropriate content automatically.

Some tactics for doing international SEO are:

  •        optimize for the most used search engine in the country of your choice and use their keyword planning tools (for example Yandex in Russia and Baidu in China)
  •        hreflang will specify the content language of your web page and help the search engine display it to the right target group
  •        translate the HTML elements of the web page used for SEO – URL, meta description and title
  •        translate the content of the webpage, including the navigation, image names and alt tags
  •        use country detection to change price currency

Interstitials

A disruptive, promotional page that is inserted in the normal website content. For example, a pop-up or lightbox that covers the whole web page, that a visitor came to see, and that needs to be manually closed to continue browsing. This makes content hard to access and reduces user experience. Having an interstitial immediately or shortly after a user clicks on your link in SERPs on your mobile site can result in a penalty.

Key performance indicators definition in SEO glossary

Key performance indicator (KPI)

It is a metric that you set yourself to measure how effectively your business or team is performing toward reaching a business objective. Some examples of KPIs in the SEO industry are monthly organic traffic, keywords in top 3 SERPs, retention rate, the number of backlinks and many, many more.

Keyword

Words or phrases that users write into the search box to find a website with matching content. Specifying a keyword and using it in your content is what helps spiders categorize your website and display it at the right time.

Keyword (not provided)

A keyword status in Google analytics. In the organic traffic section found in the Acquisition report most of the keywords are marked with (not provided). This happens because whenever a user is logged in to their Google account, the keyword they use in their search gets encrypted to protect their privacy.

This is valuable information for anyone that is trying to figure out which keywords drive the most traffic to their websites.

Fortunately, there are a few methods to get insight on some of these keywords:

  •        Check out the Search Query section in Google Analytics>Acquisition>Search console>Queries
  •        Go to Google’s search console and check out the performance report, if you scroll down you get a queries list

Keyword analysis

The process of evaluating all the keywords that you are currently using and those that you discovered during your keyword research. The important metrics for you are search volume, CPC, competition, and current SERP position. You can add a desired SERP position to the mix and group the keywords by user intent, meaning are they using these keywords when they are looking to buy a product, when they are just browsing or something else important for your website.

Keyword cannibalization

Using the same keyword for multiple web pages. This damages your SEO as you basically compete for rank positions and traffic with yourself.

Keyword categorization

A process of classifying and grouping keywords based on user intent and context at the time of the query. Keyword categorization can help with determining the keywords that users query at different stages of the buying process, so we can use them on specific landing pages that were meant for the purpose of conversion.

Keyword competition (Keyword difficulty, Keyword SEO difficulty)

Next to the search volume, keyword competition is an important metric that shows how easy or difficult it is to compete for rank on this word or phrase in the SERPs. It is a sign of the popularity of this keyword in your particular niche.

Keyword density

Keyword density is the percentage of the keyword being used on a page compared to the total number of words. It is used to determine the relevance of a web page, but there is no clear information on what the optimal percentage is. In fact, it is easier to overdo it, than it is to hit the sweet spot.

Keyword frequency (Term frequency)

Similar to keyword density, but this time we measure the total number the keyword was used on a web page. The amount of content on the web page is of no importance in this case.

Keyword funnel

Based on customer intent and what stage of the buying process they are currently in, the customer’s search terms change. We can categorize our keywords by these buying stages and optimize the specific landing pages to increase conversion.

Keyword prominence

Refers to how important or noticeable the keyword is. Prominent placement is at the start (or near the start) of the title, headings, meta description, and the opening paragraph.

Keyword proximity

Refers to how close the keywords are on the page. As an example, if the search term contains multiple words like “SEO tool for bloggers”, then the distance between the 3 relevant words is checked in the content and the closer they are together the more relevance the web page gets.

Keyword rank

This is your position in the SERP listings for a specific keyword.

Keyword research (Keyword optimization)

The process of discovering new keywords that are relevant to your business and suitable in terms of search volume and competition. Effective keyword research is crucial in the process of determining profitable niches, driving traffic and promoting your business.

Keyword stemming

In linguistics, a word stem, base or root is the most basic part of the word that holds meaning. To this root prefixes or suffixes are added creating stemmings. By using keyword stemmings we can create whole lists of different keyword variations. Example: luck, unlucky, lucky, luckless, luckiest etc.

Keyword stuffing (Keyword spam)

A black hat SEO tactic where a certain keyword is repeated over and over again on the same page in order to deceive the search engine spiders that the content is relevant for this keyword. What is most characteristic about it is that the keyword is placed into the content unnaturally creating a spammy text that will not bring value to anyone reading it.

Knowledge graph

Meant to enhance the result of a Google search, a knowledge graph pulls information from several sources. The best example of it is the knowledge panel, a box placed to the right of the regular search results containing images, various detailed information, and suggestions for further search.

All SEO terms that begin with L in the SEO glossary

Landing page

A specific page that appears after the visitor clicks on a link. These pages are optimized for promotion and conversion and are usually connected to a marketing campaign.

In SEO each landing page can have different keywords and are optimized accordingly.

Latent semantic indexing keyword (LSI keyword)

LSI keywords are words and phrases that are semantically related to your primary keyword. These words share the same context and are frequently used or found together. As an example, the LSI keywords of “SEO” are SEO tool, SEO agency, SEO audit etc.

Here is a tool that you can use to discover LSI keywords.

Lead magnet (Gated content)

Refers to content that is used to encourage potential customers (leads) to leave their email or other contact information. The most common example of using a lead magnet is offering a free ebook in exchange for the user’s email. The email lists gathered this way are then used in further marketing strategies. This lead generation strategy depends highly on SEO and is a decent way of increasing conversion rates.

Linkbait

Valuable content that other websites will naturally link to. It is unique, high in quality and informative, with a tendency to go viral. Hard to achieve, but exceptionally beneficial for SEO.

Link building (Link acquisition)

A process of increasing the quality and number of backlinks to your website. Link building is considered a major tactic in SEO and there are three approaches you can use:

  •        have great content and gather editorial links
  •        reach out to bloggers and influencers, write guest posts or submit your website to niche directories
  •        leave links in blog and forum comments (use this approach with caution, because overuse could be penalized)

Link burst

A Link burst is when you gather a big number of backlinks in a short amount of time. It can be a cause for a red flag for the search engine because it could indicate that you are using a link farm or SEO services that are creating link spam. Alternatively, it is ok to have high link velocity on a web page with content that went viral.

Link condom

A very crude way of describing the use of a nofollow attribute value in a link, as it prevents the passing of link juice (*cringe*).

Link diversity

A link building strategy where you try to collect an array of links from different types of websites (blogs, news, directories, social media) and different domains (.com, .edu) with various anchor text, as well as having both “nofollow” and “dofollow” links.

Not all SEO experts agree that this is important, but it does give a signal of a natural link profile where a certain type of link isn’t being represented more than the other.

Link equity (Link authority, Backlink authority, Link juice, Link value)

Link equity refers to the notion of a link influencing the rank of a website. It is a term describing the process of one-page passing authority or value to another through the use of hyperlinks.

Link farm (FFA, free for all)

Mostly run by automated programs and services, a link farm is a group of websites that all link either to each of the websites in the group or to a website that is paying for this service. This practice can get you a hefty manual penalty and is best avoided.

Link hoarding

A tactic employed by some websites where they try and gather as many inbound links as possible while having as few outbound links as possible. This is done to increase traffic and link popularity towards these few websites the outbound links are pointing to or to keep from passing traffic and link equity to anyone else (by marking the outgoing links as nofollow). It is considered a disreputable tactic and it can hurt just as much as having too many outgoing links.

Link popularity

Refers to the total number of backlinks a website has.  Every backlink is counted separately, even if it comes from the same website.

Link profile (Backlink profile)

A common SEO term for all the links that point to your website. Whether a link profile is good or bad will depend on the value of incoming links, proper use of alt tags and anchor text and link diversity.

Link reclamation

The process of getting lost links back. It is a tactic with a high ROI because of the high likelihood of success.

Find out more about this process and how to get started on link reclamation.

Link relevancy (Relevant link)

Describes if the two websites that are involved in the linking process are topically connected and in what degree and how relevant the website that is giving the backlink is in its own field.

Link rot

Eventually, your web pages become old. Also, the web pages you are linking to get old and very often they get moved or deleted.  The effect this process has on your web page is then called link rot. It refers to having many broken links (external or internal) and it happens when you do not do regular site audits and check your link profile.

Link spam (Blog spam, Comment spam)

A method where many links are posted in blog comments, forums, guestbooks or other similar places online, for the sole purpose of increasing your rank and without actually leaving anything of value in the post itself. The links posted in this way are mostly nofollow, so there is no actual benefit to your rank. But you do risk a penalty for using this method of link building.

Link velocity

The speed at which a website is creating new backlinks. How fast or slow you grow your backlink profile matters for your SEO. The more natural the link velocity seems, the better. Think logically, a new site with next to no content shouldn’t be getting a huge number of backlinks in a short time (also known as a link burst).

Local citation

Any mention of the company name, website address, physical address or phone number for a local business. They can impact local search engine rankings and make it easier for
the users to find and discover businesses.

Local SEO

Local SEO is a process of optimizing customer traffic based on a geographical location.

Local search

A geographically constrained search that displays businesses that meet with their customers directly (usually physical stores or service providers) based on their and the user’s location.

Long tail keyword

A highly specific phrase (usually three or more words) that matches what you are selling/offering. They are usually used by people close to the point-of-purchase and thus have a much higher conversion rate than one-word, high search volume keywords.

This article can help you out in your long tail keyword research.

Lost link

A backlink that stopped passing link equity to your website. This happens due to removal by the owner of the other website or moving of the page where the link was or where it was pointing to.

All SEO terms that start with M in the SEO glossary

Manual action (Google manual action penalty)

A big Google penalty where a human reviewer concluded that your website did not follow Google’s webmaster quality guidelines. A site that receives a manual action either gets their rank greatly reduced or they get removed from the SERPs completely. You should then try to repair the issues and apply for reconsideration when everything is fixed.

You can check if your site has a manual action (and which pages are affected) here:

https://search.google.com/search-console/manual-actions

Metadata

Metadata is used to give descriptive information on a website. It is set up by use of meta tags in the website’s code and put to use by the browser and search engine crawler. The most important tags are the title, meta description, and robots, but they are just a drop in the meta sea.

Meta description tag

An important tag describing the content of the website used by the search engine in the search result snippet. If left empty the search engine will pick a paragraph from your content to display in the snippet.

Google will also ignore your description if it is too long, so it is a good idea to stay under 757px for mobile and 940px for the desktop.

It does not necessarily influence your SEO but taking control of what is displayed in the search result snippet can greatly improve your click-through rate.

Meta keywords

A metadata element that was used to inform search engine spiders about the relevant keywords of a webpage. It was widely abused with website’s trying to manipulate the search engines and naming keywords that were not relevant to the content. This is only one of the reasons why the meta keywords are no longer used as a ranking signal.

Nowadays, you should avoid using meta keywords as the effect they have on your SEO is most likely negative.

Meta refresh (Meta refresh tag, Meta redirect)

A meta tag that instructs the browser to refresh a page after a certain amount of time. Usually used to refresh dynamic content on a web page (like the number in “Only 10 left!”). They were also used as a method of redirecting but this method is slow and not recommended for the sake of your SEO. You should use the 301 redirect instead.

Metric

A unit of measurement meant to track the performance of a website. The most important SEO metrics are organic traffic, bounce rate, keyword rank, backlink count, CTR, page load speed etc.

Mirror site defined in the SEO dictionary

Mirror site

A complete replica of a website, placed on a different URL. They are used when the original website generates too much traffic for the server to support. Mirror sites serve the population in different locations (different continents) and ensure a good user experience and fast page load.

Mobile-friendly website

A website optimized for viewing on a mobile device. This can be done in one of two ways, either by having a mobile version of your website or making the website responsive (the website scales down or changes its layout based on device screen size).

Mobile first indexing

An approach to indexing where the mobile version of a website is crawled and indexed first. The desktop version will still be indexed and ranked, but if there is no mobile version or the site is not entirely mobile optimized, it will have a negative impact on the rank.

Mobile optimization

Improving a website so it is well suited for viewing and interaction via a mobile device. Optimizing for a mobile device usually means that the layout will need to be readjusted, the text will need to be readjusted for easy reading, any navigation or CTA buttons enlarged, and image size optimized.

Morningscore (Morningscore metric)

A metric used by the Morningscore SEO tool that shows the value of your SEO. It is based on 4 metrics: traffic volume, CTR, organic traffic and CPC. If we try and simplify the calculation it looks something like this:

Monthly clicks from Google to your website x the price you would pay for the clicks in Google Ads = your Morningscore

If you’d like to learn more about the Morningscore metric, read our explainer article.

SEO definitions starting with N

Negative SEO (Negative SEO attack)

Negative SEO refers to using black hat SEO methods to lower the rank of a competitor. These include hacking the site to change the content and some off-page tactics like building spammy, unnatural links and creating duplicate content.

Nofollow link

Nofollow is an attribute value of a link. By using it we inform the search engine crawler that we do not wish to pass link equity to the website it is pointing to.

Noopener and Noreferrer

These are values set for the rel attribute of a href tag (link). They specify the relationship between the web page the link was on and the web page the link is pointing to. There is no effect on SEO, they are used for security and performance reasons.

SEO definitions starting with O

Off-page SEO

Refers to all the actions that improve your websites ranking in the SERPs that were not done on the webpage itself. Included here is link-building and marketing for the sake of exposure in the form of guest posting or social media marketing.

On-page SEO (Onsite SEO)

On-page SEO is optimization of all the individual pages on your website. It is both optimizing the content and the HTML source code in order to improve visibility and search engine rankings.

Opt-in

A clear permission by a user/customer that the marketer may send direct messages (usually emails). Many countries have clear legislation concerning sending direct messages and sending unsolicited commercial messages can earn you a hefty fine. This is why you should ask your customers for permission to send them a newsletter, promotional material or any other email before you add them to a mailing list. You are then allowed to send emails until the user opts-out.

Opt-out

A clear statement by the user wanting to be removed from a mailing list. Usually done via an unsubscribe button in the mail itself or adjusting settings in a profile. Most countries have legislation set in place that obligates the sender to give a clear chance for the user to stop getting further commercial emails.

Organic rank

Organic rank is the position of a website in the traditional organic SERP listings. It is the rank you achieve by using SEO methods and not by SEM.

Organic traffic

Organic traffic is the “free traffic” you get when a visitor finds your website through Google searches. It is the opposite of paid traffic you get through advertising and what you are trying to influence by SEO.

You can calculate the amount of organic traffic to your website by using this simple equation: Traffic volume x Click through rate = Organic traffic

Organic search results (Natural search results)

Organic search results are listings in the SERPs that get displayed because the website listed employed good SEO practices instead of paying for it.

Orphan page

A page on a website that has no links pointing to it. They cannot be found by a search bot, so they are useless for SEO.

Outbound link (Outgoing link, External link)

Links that lead away from your website. They affect your SEO as they help the search engine understand your niche and improve the trustworthiness and quality of your content.

Outreach marketing

A type of marketing where we find individuals/companies/ organizations that share our industry niche and could find what we have to offer valuable (this could be products and services or content). This type of approach is very targeted and personalized. We need to make a human to human connection or we risk our email just being classified as spam.

Outreach marketing techniques that are used for the sake of SEO include e-mail or blogger outreach for link building purposes.

Over-optimization

The practice of optimizing to please (or even trick) the search engine instead of delivering user-friendly and relevant content to the visitor. Examples of these practices include writing content to the keyword, where the keyword is unnaturally repeated in the content or gathering backlinks at a suspiciously fast rate.

Doing this might get your website penalized or downgraded in terms of SERP ranking.

SEO definitions begining with P

Page Authority (PA)

Domain authority measures how well the website will perform in SERPs and how competitive it is compared to other sites in its niche and page authority does the same but for an individual page. This is where your internal link strategy comes into play, as a page closer to the top of the hierarchy with multiple pages linking to it, will be given more importance and a higher PA than those further down.

Page cloaking (Website cloaking, IP cloaking)

A black hat SEO technique where the search engine is presented with a version of content that is different from that which the visitor sees. This is done by delivering content based on the user’s IP address.

Page speed (Page load speed, Page load time, Page response time)

Page load speed is a measurement of how much time it takes for your entire web page content to be displayed in the browser window.

The loading speed affects both your rank and user experience. Visitor bounce rate tends to be higher on slower web pages and it even affects the dwell time and engagement.

PageRank (PR)

Google’s algorithm that measures the relevance and importance of a website in order to rank them in the SERPs. It assigns a PR number to the website based on all the other websites that link to it and their PR.

Pageview (Page impression)

A request to load a page of a website. More plainly, it is each time a visitor loads a specific page. This is tracked by Google Analytics’ tracking code and if the visitor reloads the same page it will be counted as an additional page view.

SEO dictionary definition of paid traffic

Paid traffic

Any incoming traffic to your website that resulted from a visitor clicking or tapping on an ad you are paying for. It is a very popular strategy as the results are almost instantaneous. Two well-known paid traffic platforms are Google Ads and Facebook.

Page title (Title tag)

A page title is a clickable headline that appears in the SERPs for a specific page on your website. It is the most visible part of the SERP snippet and has a big impact on your CTR, SEO and social sharing.

To set it yourself you need to use the title tags in your HTML source code.

If your title is too long, Google’s algorithm will try and find an appropriate one itself. So, it is a good idea to stay under 487px for the mobile and 568px for the desktop.

Paid links (Link buying)

The process of purchasing backlinks that pass link equity. This includes any type of payment like exchanging products or services in exchange for links or giving free products to reviewers or influencers, not to mention some of the black hat techniques. It is a risky method that could earn you a penalty.

Paid search engine result

A Google feature where you pay for a position at the top or bottom of the SERP’s sponsored ad section by using Ads or Google shopping.

Poison words (Forbidden words, Filter words)

Words that degrade the quality of the page for search engines who classify it as being of low quality. These are usually words and phrases that trigger mistrust or loss of respect.

There is no exact list of poison words, but it is suspected that phrases like “buy PageRank” or “buy backlink”, terms related to gambling, politically incorrect terms and vulgar language can get your page buried in the SERPs, especially when used in the web page URL, title and description.

Precision

Probably the number one reason why Google is the most popular search engine in the world. Google search engine’s high precision allows it to list accurate and relevant results that satisfy the query. Search spam and the complexity of the human language negatively impact this ability.

Primary keyword (Main keyword, Head keyword)

The most used keyword on a web page, with the most potential to drive traffic. Since your content can be optimized for a number of keywords, it is a good idea to choose the one primary and then use it in your page title, content headline and in the first paragraph. That said, keep in mind to always write your content as naturally as possible and don’t try to shove in a keyword unless it makes absolute sense.

Pull channel

Channels used to draw the customers towards your product or service. These usually include search engines and databases like Google, Bing or YouTube.

Pull marketing

A marketing approach that tries to draw customers in using unobtrusive methods. The potential customer is in the decision part of the buying process and is actively searching for a product or service. We just need to make sure that our product is displayed before them at that time and this we do by optimizing for the same keywords the potential customer is typing into the search bar when trying to find the wanted product or service.

This strategy has a higher conversion rate than the traditional (push) marketing and often creates loyal customers or followers.

Read more about pull marketing.

Push channel

Channels used to display your product in front of the potential customer no matter if he requested the information or not. These include ads on social media, YouTube and Google Display Network.

Push marketing

In this marketing approach, you try to push a message by displaying an ad to a potential customer without them showing interest first. These are ads before the video on YouTube, banners, and pop-ups on websites or any other unwanted display of your product or service.

It is a very traditional way of marketing and often used because it is cheaper than the pull alternative. On the other hand, it is considered interruptive so many internet users develop something called “banner blindness” where they intentionally ignore anything that looks like an add.

SEO glossary's terms with Q

Query Deserves Diversity (QDD)

One of Google’s ranking algorithms. It tries to match user intent by displaying broader match results. Google monitors user behavior and identifies search patterns where the user did not find the results relevant (the user either gives up the search, tries a different query without clicking on the result or bounces from site to site).

Query Deserves Freshness (QDF)

This SEO phrase describes one of Google’s ranking algorithms. Its focus is on delivering the freshest content for certain queries.  These include the latest trends and news, hot topics and recurring events and they are determined based on search volume spikes.

SEO glossary's terms with R

Reciprocal linking

An agreement between two websites to provide backlinks to each other. It should be done with caution, as exchanging backlinks with a company that doesn’t share a topic with you might hurt your site’s backlink profile and make it harder for the search engine spiders to classify your site’s topic.

Referral traffic

All traffic coming into your website outside of the search engine. Here we include all the backlinks you have gathered and links from other platforms like social media.

Reinclusion (Reconsideration request, Google re-inclusion)

When your website receives a manual action, you will have to request a review after fixing the issues to be reincluded to the SERPs or start climbing the ranks again.

You can select Request review in the Manual actions report

https://search.google.com/search-console/manual-actions

Relative URL (Relative link, Relative path)

A link used for internal linking. It is a short path to a file, HTML page, image or something else we link to. This link is used as a part of the anchor tag but doesn’t contain a protocol or domain name.

Example of an anchor tag using a relative path: <a href=”/images/logo.png”>Our logo</a>

There are two types of paths used in internal linking – one being the relative and the other absolute. There is, however, no indication that one is more beneficial than the other in terms of SEO.

Reputation management (Rep management, Online reputation management, ORM)

A process where we attempt to shape how a person, brand, product or organization are perceived online.

SEO practices are used in this process to:

A few days is normal, but if it takes a few weeks you might want to consider submitting it manually to the search engine.
