Alt Text

By Dan Kurtz 1 min read

Alt text is a written description of an image, embedded in the HTML img tag. Screen readers read it aloud for visually impaired visitors, and search engines use it to understand what an image depicts.

Well-written alt text describes the image in one plain sentence and, when natural, includes the target keyword for the page. It’s a small on-page SEO factor with an outsized accessibility benefit.
