Alt tags, also known as “alt attributes” or “alt descriptions,” are used to provide a text description of an image on a web page. They are used by search engines to understand the content of the image and to provide relevant information to users who may be unable to see the image, such as those using a screen reader or those with a slow internet connection. To improve your website’s SEO using alt tags, you should ensure that all images on your website have a meaningful and descriptive alt tag. The alt tag should accurately describe the content of the image, using keywords that are relevant to the rest of the content on the page.
For example, if you have an image of a red apple on a page about different types of apples, an appropriate alt tag for the image would be something like “red apple” or “delicious red apple.” Avoid using generic alt tags like “image,” “picture,” or “photo” as they don’t add any value to the users or the search engines.
It’s also worth noting that the alt tag is not only used by search engines but also by assistive technologies and other browsers to understand the images on the page, so it’s always good practice to use them.
