What Is a Website Accessibility Audit?
A website accessibility audit is an automated and heuristic evaluation of a website's code and design to ensure compliance with the Web Content Accessibility Guidelines (WCAG 2.2 Level AA) and legal standards like the Americans with Disabilities Act (ADA) and the European Accessibility Act (EAA). It ensures that individuals with visual, auditory, motor, or cognitive disabilities can perceive, navigate, and interact with the site equally.
A website accessibility audit inspects color contrast, keyboard accessibility, semantic HTML, ARIA labeling, and screen-reader compatibility against WCAG 2.2 AA standards.
What SuperAudit Evaluates in an Accessibility Audit
Exhaustive verification of WCAG 2.2 Level A and AA success criteria.
Color Contrast & Visual Perception
Calculates luminosity ratios for normal text (minimum 4.5:1), large text (3:1), and UI components against WCAG standards.
Keyboard Navigation & Focus States
Verifies complete tab navigation, focus rings visibility, skip-to-content links, and keyboard trap prevention.
Semantic HTML & Landmark Structure
Inspects proper use of header, main, nav, footer, article, and strict H1-H6 hierarchy without skipped levels.
ARIA Labels & Interactive Controls
Validates aria-expanded, aria-controls, aria-labelledby, and role attributes across custom interactive widgets.
Images, Media & Alternative Text
Flags missing, generic ("image", "photo"), or redundant alt text attributes on informative and decorative images.
Form Accessibility & Error Association
Checks that all form inputs have explicitly associated label elements, descriptive placeholder text, and aria-describedby errors.
Accessibility Violations SuperAudit Identifies
Common architectural and conversion bottlenecks detected across thousands of evaluated websites.
Missing Visible Focus Indicators
CriticalRemoving outline: none without providing an accessible replacement leaves keyboard-only users unable to see where they are.
Sub-4.5:1 Text Contrast
CriticalLight gray copy on white backgrounds fails WCAG AA standards, making text unreadable for visually impaired users.
Unlabeled Icon Buttons
HighHamburger menus, shopping carts, and close modal buttons consisting solely of SVG icons without aria-label attributes.
Skipped Heading Levels
MediumJumping from H1 directly to H3 or H4 confuses screen-reader users navigating by document structure.
