An accessibility audit is a systematic review of a website or application against WCAG (Web Content Accessibility Guidelines) standards. It identifies barriers that prevent users with disabilities — visual, motor, auditory, or cognitive — from using the product. Audits produce a prioritised list of failures with remediation guidance.
When to use
Run an accessibility audit before major releases, after significant design changes, or whenever you need to verify WCAG 2.1 / 2.2 compliance for legal, procurement, or product quality reasons.
Evidence
•96.3% of home pages have detectable WCAG failures, based on analysis of 1 million sites — WebAIM Million 2024
Automated accessibility audits check color contrast ratios, image alt text, heading hierarchy, form labels and error messages, keyboard navigability, ARIA roles and attributes, focus management, link purpose, and landmark regions. These rule-based checks cover the majority of programmatically detectable WCAG 2.2 success criteria.
How it works
1.Page is crawled and a DOM snapshot is captured.
2.Rule engine evaluates each WCAG success criterion that is deterministically testable.
3.Color contrast is computed for all foreground/background pairs.
4.ARIA attribute validity and landmark structure are verified.
5.Keyboard focus order and focus visibility are simulated.
6.Findings are ranked by severity and WCAG level (A, AA, AAA).
Automated tools typically detect 30–50% of all WCAG issues, because many failures require human judgment — context-dependent alt text quality, cognitive load, and complex interaction patterns cannot be fully machine-tested. VertaaUX uses AI heuristics alongside deterministic rule checks to increase coverage beyond standard automated tooling.
When to use
Use automated auditing as a fast, scalable first pass — it catches the majority of high-frequency, rule-based failures. Follow up with manual testing and assistive technology review for comprehensive coverage.
Audit on every release cycle at minimum. Best practice is to embed automated accessibility checks into CI/CD so every pull request is verified before merge. Run a full manual audit quarterly, and always audit after major design system changes, new component libraries, or significant content restructuring.
When to use
Teams shipping frequently benefit most from CI/CD-integrated automated checks that block inaccessible code before it reaches production, reducing remediation cost significantly.

What is the difference between manual and automated accessibility testing?
Automated testing is fast, scalable, and consistent — it runs across every build with no human time cost. Manual testing catches context-dependent issues: meaningful alt text quality, cognitive flow, screen reader announcement logic, and complex keyboard interaction patterns. Best practice is to use both: automated for coverage and speed, manual for depth and judgment.
How it works
Automated tools parse the DOM, compute contrast ratios, validate ARIA semantics, and simulate keyboard navigation programmatically. Manual testers use screen readers (NVDA, JAWS, VoiceOver), keyboard-only navigation, and cognitive walkthroughs to catch what code analysis misses.
Enter your URL, and VertaaUX runs an AI-powered crawl followed by a WCAG 2.2 rule engine across color contrast, heading structure, alt text, form labels, keyboard focus, and ARIA attributes. Results are delivered as an actionable report with issue severity, WCAG criterion, CSS selector, and fix priority — ready to share with your development team.
How it works
1.Submit your URL — no installation required.
2.VertaaUX crawls the page, renders JavaScript, and captures a full DOM snapshot.
