Write useful captions and descriptions that match the image and help readers instead of repeating the same phrases unnaturally.

Image descriptions work best when they provide information a reader actually needs. Repeating a target phrase in filenames, captions, and alt text can make content awkward and less accessible. Describe the image’s role on the page and use terminology that fits the subject.

How to approach it

For a tutorial screenshot, explain the visible step. For a product image, identify the product or feature shown. Keep surrounding text helpful and accurate, and avoid describing details that are not visible. A natural description is more useful than a string of unrelated keywords.

Checks before you share

Keep an untouched source file, inspect the exported copy at full size, and confirm that the result suits its intended use. If the image contains private information, check the entire frame and its metadata before publishing.
