What it covers

Web accessibility testing is the process of evaluating a website or web application against WCAG 2.2 Level AA — the standard courts, regulators, and laws worldwide treat as the benchmark for accessible digital content. Automated tools catch roughly 30–40% of violations. The rest require a human with assistive technology. Our testing combines both to give you a complete picture.

  • Page content and structure
  • Keyboard navigation and focus management
  • Screen reader compatibility (NVDA, JAWS, VoiceOver)
  • Colour contrast and visual design
  • Forms, errors, and interactive components
  • Third-party embeds and iframes

Frequently asked questions

Common questions about testing service services.

A structured evaluation of your website against WCAG 2.2 to identify barriers preventing people with disabilities from using it. Combines automated scanning with manual and assistive-technology testing.

Automated scanning runs in hours. Manual expert review takes 2–5 business days depending on scope. Full findings report delivered within 24h of manual review.

Every issue tagged by severity (critical/serious/moderate), WCAG success criterion, number of instances, affected user groups, and a code-ready fix. Exportable to PDF or CSV.

Yes. Our reviewers test with NVDA, JAWS, VoiceOver, keyboard-only navigation, and high-contrast mode. Automated tools alone miss 60–70% of real barriers.

Automated tools check for known code patterns — missing alt attributes, colour contrast failures, heading structure. Manual testing checks whether a screen reader actually announces things correctly, whether keyboard focus order makes sense, whether error messages are useful.

Yes. One retest is included in the Pro Report tier. For ongoing coverage, scheduled re-audits catch regressions before they become demand letters.
