Evidence before intervention
Accessibility quick review.
Start with code; finish with people.
What to verify
The health audit checks observable HTML foundations and the color tool calculates contrast. Conformance still needs keyboard, zoom, screen-reader, error, focus and task-based review.
- Run the health audit for landmarks, language, image alternatives, link names and form labels.
- Use the contrast checker for proposed foreground and background pairs.
- Complete keyboard-only journeys at 200% and 400% zoom.
- Test important tasks with representative assistive technologies and users where appropriate.
How to use this guide
- Run the free website audit tool. It checks up to five public pages on one website plus its robots and sitemap endpoints, and the result stays in your short-lived session.
- Verify the finding with owner-controlled data where it exists, such as Search Console, Bing or Chrome UX Report (CrUX) field data. The audit does not submit pages to Google or change the website.
- Fix the agreed issue, then run the same check again. Mark an issue verified only when it disappears from new evidence.
For the human checks that HTML alone cannot prove, use the website audit checklist.
