What We Check

A complete WCAG 2.1 / 2.2 + ADA / Section 508 / EAA conformance audit, broken down into the eight categories that account for 95% of real-world issues.

  • Images & Media

    Missing or non-descriptive alt text, Decorative images not marked as such Missing captions or transcripts for video content.

  • Color & Contrast

    Text-to-background contrast ratios below AA/AAA thresholds, Reliance on color alone to convey meaning (e.g., red = error).

  • Keyboard & Focus

    Elements unreachable by keyboard, Missing or invisible focus indicators, Keyboard traps where users can't tab out.

  • Forms

    Inputs without associated labels, Missing or unclear error messages, Unclear required-field indicators.

  • Structure & Semantics

    Incorrect heading order (H1 → H3 skipping H2), Missing landmark regions (main, navigation, footer), Improper use of ARIA roles.

  • Navigation

    Missing skip-to-content links, Inconsistent navigation across pages, Unclear link text ('click here' instead of descriptive text).

  • Assistive Tech
