An automated test can tell you an image has no alternative text. It cannot tell you whether the text that is there actually describes the image. Review Alt Text puts the two side by side so a person can judge quickly.
Opening it
On a scan's results page, in Automated Scan Findings, choose Review Alt Text. It shows every image found across all the pages in that scan.
What you see
A grid of cards. Each card shows the image, its alternative text in quotes, or a No alt text badge if it has none, and the page it was found on.
- Missing alt text only narrows the grid to images with none.
- Search finds images by their alternative text or by page, which is handy for spotting the same unhelpful text used over and over.
What to look for
- File names, such as "IMG_2041.jpg" or "hero-banner-final". These are read aloud to screen reader users and mean nothing.
- The same text on different images. Usually a template filling in a default.
- "Image of" or "picture of". Screen readers already announce that it is an image.
- Text that does not match the picture, often left over after an image was replaced.
- Images containing words, such as a banner with an offer on it. The alternative text needs to include those words.
Images that should have no description
Purely decorative images, such as a background flourish, should have empty alternative text so screen readers skip them. So a missing description is not always wrong. The question is whether the image carries information. If it does, it needs a description. If it does not, it should be marked as decorative.
