Frequently Asked Questions

What accessibility standards does this tool check?▾
This tool checks against WCAG 2.1 Level A and AA criteria — the most widely adopted accessibility standard and the basis for ADA, EN 301 549 (EU), and AODA (Canada) compliance requirements.
Is a free online checker enough for full WCAG compliance?▾
Automated tools can detect ~30-40% of WCAG issues. Issues like color contrast, keyboard navigation, focus order, and cognitive load require manual testing. Use this tool as a starting point, not a complete audit.
What is the difference between errors, warnings, and notices?▾
Errors are definite WCAG violations that will directly impact users with disabilities. Warnings are likely issues that need review. Notices are best-practice recommendations or items needing manual verification.
What does the Accessibility Score mean?▾
The score (0–100) reflects how many automated checks pass. Each error costs 15 points, warnings cost 5 points. A score of 90+ = A, 75+ = B, 60+ = C, 45+ = D, below 45 = F.
Why should I fix accessibility issues?▾
Accessibility improves UX for everyone, not just users with disabilities. It also reduces legal risk (ADA lawsuits hit record highs in 2024), improves SEO (Google uses accessibility signals), and expands your audience.
What is alt text and why does it matter?▾
Alt text describes images for screen readers, search engines, and users who cannot see images. Missing alt text means blind users hear "image" or a filename instead of the content. WCAG 1.1.1 requires all non-decorative images to have alt text.
What is a skip navigation link?▾
A "Skip to main content" link is the first focusable element on the page, visible on keyboard focus. It lets keyboard and screen reader users skip past the navigation menu directly to the main content — required by WCAG 2.4.1.
