ALT Text is text associated with an image that serves the same purpose and conveys the same essential information as the image. In situations where the image is not available to the reader, perhaps because they have turned off images in their web browser or are using a screen reader due to a visual impairment, the alternative text (ALT Text) ensures that no information or functionality is lost. Absent or unhelpful alternative text can be a source of frustration for visually impaired users.

Search engines use ALT Text to decide what an image is depicting, since a search engine cannot “see” an image like a human can. properly formatted ALT Text can improve SEO, especially for image search results.

ALT Text is important for both humans and robots and is strongly recommended for all images and graphics on a website.

Example of ALT Text:

<img src=”/imagepath/imagename.png” alt=”ice cream truck”>
