Why ISO Matters

Over 1 billion people globally have disabilities. In the US, ADA web accessibility lawsuits exceeded 4,000 in 2024. Beyond legal risk, accessible websites serve 15-20% more users effectively. Google also uses accessibility signals as quality indicators for rankings.

Frequently Asked Questions

What is WCAG 2.1?

WCAG (Web Content Accessibility Guidelines) 2.1 is the international standard for web accessibility. Level A is minimum compliance, AA is the legal standard in most jurisdictions, and AAA is the highest level. Our scanner checks against AA with notes on AAA improvements.

Is my website legally required to be accessible?

In the US, the ADA applies to most businesses with websites. In the EU, the European Accessibility Act (2025) mandates compliance. In many countries, public sector sites must meet WCAG AA. Regardless of legal requirements, accessibility improves user experience for everyone.

Can automated tools catch all accessibility issues?

No — automated tools typically catch only 30-40% of accessibility issues. Our AI agents go further by evaluating context (e.g., "is this alt text actually meaningful?" vs just "does alt text exist?"). However, manual testing with assistive technology is still recommended for full compliance.
