Frequently Asked Questions

Common questions about the website accessibility checker, ADA compliance, WCAG standards, and how the audit works.

Why run a website accessibility audit for ADA compliance?

Web accessibility is not just a nice-to-have. ADA (Americans with Disabilities Act) lawsuits against websites have increased every year since 2018, and courts consistently point to WCAG 2.1 AA as the standard for compliance. Over one billion people worldwide live with some form of disability, and inaccessible websites exclude them from essential services, information, and opportunities.

Beyond legal compliance, accessibility overlaps with good engineering: semantic HTML, clear heading hierarchies, proper labelling, and keyboard support all improve SEO, maintainability, and user experience for everyone. Running a website accessibility checker is the fastest way to identify what needs fixing.

This accessibility checker gives you a quick snapshot across 8 WCAG categories. For a complete ADA compliance audit, combine it with our per-criterion WCAG compliance checker, browser-based tools (Lighthouse, axe DevTools), manual keyboard testing, and real screen reader testing.
