Images: alternative text (WCAG)
WCAG 1.1.1 requires a text alternative for non-text content.
Pass condition in our engine: Informative images have non-empty alt (or the page has no images).
This WCAG check is part of SEO-GEO scoring 2.2.1, last updated 2026-09-18. About 90 percent of the evaluation runs on the HTML we crawl, so you can verify the same pass condition with a free report.
1. Problem description
Screen-reader users hear “image” with no description if alt is missing. Search and AI systems also lose the only textual description of the photo. Decorative images should use empty alt, not a missing attribute.
2. Most common causes
- CMS uploads without an alt field.
- Icons implemented as <img> with no alt.
- Client-rendered galleries not in the HTML we fetch.
3. How to fix it
- Describe the meaning of informative images in alt.
- Use alt="" for decorative images.
- Do not stuff keywords into alt.
