Alt Text Best Practices

Be descriptive: Explain the content and purpose of the image, like “Illustration of a dashboard UI showing user analytics.”

Don’t start with “image of…”: Screen readers already announce it’s an image.

Avoid keyword stuffing: Use natural language that actually describes the image.

Decorative images? Skip it: If an image doesn’t add meaning, use an empty alt="" so it’s ignored by screen readers.

Alt text is essential for accessible design—and it’s often one of the easiest SEO wins on a site.
