Website Accessibility Audit
Audit your website or app for accessibility issues — WCAG 2.1 compliance, screen reader compatibility, keyboard navigation, color contrast, form usability, and alt text. Outputs a categorized issue list with severity, fix instructions, and a remediation priority roadmap. Helps avoid lawsuits and reach more customers.
Pro tip
Describe your site page by page, or paste the HTML/content. Include your color palette HEX codes — contrast ratio failures are the most common and easiest to fix.

Conduct a comprehensive accessibility audit:
1. **Color contrast check** — evaluate every color combination against WCAG AA minimums (4.5:1 for normal text, 3:1 for large text). List every failing pair with current ratio and suggested fix.
2. **Keyboard navigation** — can a user navigate the entire site without a mouse? Tab order logic, focus indicators, skip-to-content links, modal/dropdown keyboard traps.
3. **Screen reader compatibility** — heading hierarchy (H1→H2→H3 in order?), landmark regions (nav, main, footer), ARIA labels on interactive elements, image alt text quality.
4. **Form accessibility** — label associations, error messaging, required field indicators, input types, autocomplete attributes.
5. **Media accessibility** — video captions, audio transcripts, animation pause controls, auto-play issues.
6. **Responsive & touch** — touch target sizes (minimum 44×44px), text scaling, zoom support, content reflow.
7. **Issue summary table:**
| Issue | WCAG Criterion | Severity (Critical/Major/Minor) | Fix Difficulty (Easy/Medium/Hard) | Fix Instructions |
8. **Remediation roadmap** — prioritized by: severity × fix difficulty. Phase 1 (critical + easy — do this week), Phase 2 (major — next 30 days), Phase 3 (minor — ongoing improvement).
9. **Quick wins** — 5 changes that take under 30 minutes each and make the biggest impact.
10. **Legal context** — one paragraph on ADA/accessibility lawsuit risk for businesses your size. Not legal advice, but awareness.
Notes: Claude provides thorough, well-organized audits. Paste actual HEX codes for precise contrast ratio calculations. For the most complete audit, describe every page template (home, product, checkout, contact) separately.
