WCAG 2.2 is the latest official Web Content Accessibility Guidelines standard, adding 9 new success criteria focused on mobile usability, low vision, and cognitive accessibility.

What's the difference between WCAG 2.1 and 2.2?

WCAG 2.2 builds upon WCAG 2.1 by introducing additional success criteria that address focus appearance, dragging movements, target size minimums, and accessible authentication.

Is my website legally required to be accessible?

In many jurisdictions, yes. Organizations in the US must comply with ADA Title III and Section 508, while European businesses must align with the European Accessibility Act (EAA).

What is ADA Title III?

ADA Title III prohibits discrimination on the basis of disability in places of public accommodation, which US federal courts increasingly apply to commercial websites.

Section 508 requires US federal agencies and organizations receiving federal funding to make their electronic and information technology accessible to people with disabilities.

The European Accessibility Act (EAA) is a European Union directive requiring products and services—including e-commerce and digital platforms—to meet strict accessibility standards.

The Accessibility for Ontarians with Disabilities Act (AODA) requires public and private organizations in Ontario, Canada to meet WCAG 2.0 Level AA accessibility standards.

Can I scan pages behind a login?

Yes, with our Pro and Agency plans, you can utilize authenticated scanning via session cookies or credentials to audit password-protected areas.

What's the difference between WCAG levels?

Level A sets basic accessibility features, Level AA addresses the most common barrier thresholds (and is the global legal standard), while Level AAA provides the highest tier of accessibility design.

How often should I scan my website?

Continuous or monthly scanning is recommended to ensure new code, blog posts, or site modifications do not introduce new accessibility regressions.

What do the scan results include?

Reports detail specific WCAG success criteria failures, element code snippets, impact severity ratings, and actionable code fixes for your development team.
