Accessibility is about making a website usable for people with different needs, not chasing a perfect automatic testing score. Automated audits can catch many issues, but manual testing remains essential.

Before you begin

You will need access to the website or account involved, a list of important public URLs, and permission to make the relevant changes. Save a backup of configuration before editing DNS, server rules, source code or search settings. A successful check means the specified condition was verified—not that Google or Bing will index or rank the page.

Step-by-step instructions

Step 1: Run automated checks

Use Lighthouse and an established accessibility testing tool such as axe on representative pages. Record specific elements, rules and evidence instead of a single site-wide percentage.

What success looks like: Each reported issue points to an element and reproducible behavior.

Step 2: Test keyboard navigation

Move through the site using Tab, Shift+Tab, Enter and Escape. Confirm focus visibility, sensible order, menus, dialogs and forms.

What success looks like: Critical workflows work without a mouse.

Step 3: Fix names and semantics

Ensure form inputs have useful labels, buttons have accessible names, headings are structured and informative images have meaningful alt text.

What success looks like: Assistive technologies can identify purpose and relationships.

Step 4: Review contrast and responsiveness

Check text contrast, zoom/reflow, touch target sizes and error messages. Validate with actual visual inspection, not just a passing tool score.

What success looks like: Content remains readable and actionable on small screens or zoom.

Step 5: Retest with human judgement

Run the automated suite again, test keyboard flows and ideally involve assistive technology users. Document remaining issues and maintenance responsibility.

What success looks like: The fixes are confirmed by both tests and user-centered review.

Final verification checklist

  • Each reported issue points to an element and reproducible behavior.

  • Critical workflows work without a mouse.

  • Assistive technologies can identify purpose and relationships.

  • Content remains readable and actionable on small screens or zoom.

  • The fixes are confirmed by both tests and user-centered review.

Common mistakes to avoid

  • Calling Lighthouse 100 a legal compliance certificate.

  • Writing alt text that says image without conveying meaning.

  • Removing focus outlines for aesthetic reasons.

Frequently asked questions

Is Lighthouse accessibility score enough?
