The power of alt tags

Alt tags are important elements in SEO, because they provide search engines with valuable context about the images on your website. Search engine crawlers can't see images the same way humans do, and they rely on alt tags to understand the context and relevance of your images. Optimizing alt tags with the right keywords, your images has a higher chance of getting indexed and show up on the result pages. This creates more organic traffic, as content from your website are more visible.

Enhancing website accessibility through alt tags

Alt tags are a big part of the overall accessibility and usability of your website. Just as alt tags help search engines understand the context of your images, they also serve as alternatives for people with visual difficulties, or people who use screen readers. This ensures that every user on your website can understand the purpose and content of images, which is important, as images often provide a lot of key information.

why do keyword rankings fluctuate so much and how to troubleshoot them

Have any questions?

Your alt tags should include concise and descriptive text that explains the exact content and purpose of the image. This text should provide relevant information, such as as any text within the image, contextual details, and keywords related to the image.

Your main focus needs to be on providing the user with a very in descriptive text about what can be seen on the image. Imagine the user can't see the image - what details should be written to ensure that the user fully understand what the image is supposed to show?

The first mistake to avoid is using alt tags that include generic or irrelevant descriptions.

Secondly, you shouldn't stuff your alt tags with keywords, as this isn't informative at all.

And lastly, don't leave alt tags empty for informative images, and make sure to update your alt tags if you change your images on your website.

No, there is no specific restrictions. Though, it is important to understand that providing descriptive and relevant text to the image, avoiding very long texts, and ensuring that alt tags aren't used for decorative images are key factors to being successful with alt tags.

No, alt tags themselves do not directly affect page load speed. Alt tags er simply added to HTML elements and are mostly very lightweight. However, using very long and complex alt text could indirectly impact load speed if it increases the size of the HTML file a lot. There is a lot of other factors that play a significantly bigger role when it comes to page load speed, such as image file size, server response time, and network conditions.

Alt tags contribute to a good user experience by providing descriptive alternatives to images in the form of text, meaning that every user can understand the content on the page, without having to see the visuals.

Alt tags are specifically designed to provide alternative text descriptions for images, not videos. For videos, however, features such as captions and transcripts should be used instead.

If you have a large amount of images without alt tags on your website, you should start adding alt tags to them strategically. Prioritize adding descriptive alt tags to the images that are most crucial, meaning the ones that are integral to understand the content on your website.

You can also utilize tools to help you keep an overview on images that needs alt tags, and on which page they can be found on. That way, you can systematically add alt tags in the most optimal order.
