How to test your website for WCAG compliance

Why the usual way fails

Manual accessibility testing is an extremely slow and resource-intensive task that requires developers to inspect every DOM element, evaluate color contrast ratios, and verify tab key order across multiple viewport dimensions. Relying on browser extension utilities or localized development tools can produce inconsistent test environments across team members, since browser settings, extension versions, and local extensions interfere with standard DOM rendering. Third-party accessibility overlay scripts fail to fix core source code defects, consume extra client browser memory, and are routinely rejected by federal courts as non-compliant solutions for accessibility laws. Without an automated server-side scanner that runs against live rendered pages, teams lack a centralized way to generate repeatable accessibility audit reports containing exact code snippets and element selectors for immediate remediation.

How Website Accessibility Checker helps

Website Accessibility Checker provides a web-based testing platform that audits live web pages against WCAG 2.2 AA standards without requiring software installations or tracking scripts. The system opens the submitted URL in a headless Chrome browser session and runs axe-core and Pa11y rule engines in parallel to inspect the fully rendered client DOM for accessibility defects. Every scan evaluates over fifty WCAG rules, detecting missing form labels, broken landmark hierarchies, low contrast text pairs, focus traps, and incorrect ARIA attributes. The engine outputs an organized diagnostic report card sorted by issue severity, displaying specific DOM element selectors along with copy-pasteable code recommendations to streamline developer fixes.

Step by step

1. Navigate to the online audit platform and paste any public website address or domain name into the primary scan input field.
2. Choose your target legal compliance framework from nine global jurisdictions, such as United States ADA Title III, European Union EAA, or Canadian AODA.
3. Initiate the scan to let the dual engine render your web page in a headless Chrome session and analyze the live DOM structure.
4. Review the generated report card to inspect detected violations grouped by severity alongside exact element selectors and code fixes.
5. Export the final compliance audit results to a downloadable PDF document or share a link directly with your engineering team.

Tips

• Execute scans against live rendered DOM nodes rather than raw static HTML files to properly capture dynamic elements generated by modern JavaScript frameworks.
• Set the target legal jurisdiction selector before running scans so exported PDF reports correctly reflect regional regulatory standards like ADA Title III or EAA.
• Prioritize fixing high-severity structural defects such as missing form input labels, broken screen reader landmarks, and low contrast text pairs before addressing minor aesthetic guidelines.
• Combine automated DOM testing with manual keyboard navigation checks to verify that custom interactive modals and dropdown menus manage focus accurately for screen reader users.
