A short text that describes an image, in the alt attribute of its HTML. Screen readers read it out to people who can’t see the image, browsers show it when the image doesn’t load, and search engines use it to understand the image.

How long should alt text be?

One sentence, about 125 characters at most. Say what the image shows and why it is on the page. Leave out “image of”: screen readers announce an image anyway.

Does alt text help SEO?

Google says it uses alt text, along with the image itself and the page around it, to understand what an image shows. Write it for people first; a keyword belongs in it only where it describes the image.

When should an image have empty alt text?

When it is pure decoration, such as a background texture or a divider: alt="" tells screen readers to skip it. The generator says so when an image looks decorative.
