Alt text should be provided for images, so that screen reader users can understand the message conveyed by the use of images on the page. This is especially important for informative images (such as infographics). When creating the alt text, the text should contain the message you wish to convey through that image, and if the image includes text, that text should also be included in the alt.

The exception to this rule is when an image is used purely for decoration; in this case, the alt text can be left empty (link is external) so that the screen reader user is not distracted from the more important content on the page.

If an image is the only content of a link, the screen reader will read the file name if alt text is not provided. Always provide alt text for images that are used as links.

Search engines will also use the alt text when crawling your site for relevance to the subject. 1-Stop Design can create and design your website.  Contact us for more information.
