As accessibility regulations evolve and digital experiences become more complex, performing a complete accessibility audit is essential. In 2026, accessibility audits are no longer one-time tasks—they are ongoing processes that help ensure websites remain WCAG 2.2 and ADA compliant while delivering inclusive user experiences.
This guide walks you through a step-by-step approach to conducting a comprehensive accessibility audit in 2026.
What Is an Accessibility Audit?
An accessibility audit is a structured evaluation of a website to identify barriers that prevent people with disabilities from accessing content. Audits measure compliance against recognized standards such as WCAG 2.2, which is widely used as the benchmark for ADA compliance.
A complete audit examines:
- Code structure and semantics
- Visual design and contrast
- Keyboard navigation
- Screen reader compatibility
- Forms, media, and interactive elements
Step 1: Define Scope and Standards
Before starting an audit, clearly define:
- Which pages will be audited (homepage, templates, key user flows)
- Target compliance level (WCAG 2.2 Level A or AA)
- Devices and browsers to test (desktop, mobile, assistive technologies)
In 2026, most organizations aim for WCAG 2.2 Level AA, as it aligns closely with legal expectations.
Step 2: Run Automated Accessibility Scans
Automated accessibility tools quickly identify common issues and provide a baseline assessment.
What Automated Tools Detect
- Missing alt text
- Color contrast failures
- Incorrect heading structure
- ARIA and semantic HTML errors
- Form labeling issues
Recommended Tools
- Accessibility checkers (site-wide scans)
- Browser extensions like axe or Lighthouse
- CMS-based accessibility plugins
Automated scans typically identify 30–50% of accessibility issues, making them an essential first step.
Step 3: Perform Manual Keyboard Testing
Keyboard accessibility is a core WCAG requirement. All interactive elements must be usable without a mouse.
Manual Checks Include:
- Tab order follows visual flow
- Focus indicators are visible
- No keyboard traps
- Dropdowns, modals, and sliders are accessible
This step often reveals issues that automated tools cannot detect.
Step 4: Test with Screen Readers
Screen reader testing ensures content is understandable to visually impaired users.
Common Screen Readers in 2026:
- NVDA (Windows)
- VoiceOver (macOS & iOS)
- JAWS (enterprise environments)
What to Test:
- Headings and landmarks
- Image descriptions
- Form instructions and error messages
- Dynamic content announcements
Screen reader testing validates the real-world accessibility of your website.
Step 5: Review Visual Accessibility
Visual accessibility supports users with low vision or color blindness.
Key Areas to Review:
- Text and background contrast
- Font size and spacing
- Zoom and responsive behavior
- Color-dependent information
WCAG 2.2 emphasizes readability and adaptability across devices.
Step 6: Evaluate Forms and Interactive Elements
Forms are among the most common accessibility failure points.
Check for:
- Proper labels and instructions
- Clear error messages
- Accessible validation feedback
- Logical tab order
Interactive components like pop-ups and carousels should be fully accessible via keyboard and screen readers.
Step 7: Document Issues and Prioritize Fixes
A complete accessibility audit includes detailed documentation.
Your Audit Report Should Include:
- Identified issues
- WCAG success criteria references
- Severity levels (critical, moderate, minor)
- Recommended fixes
- Screenshots or code references
Prioritize issues that block core functionality or legal compliance.
Step 8: Fix, Retest, and Monitor
After remediation:
- Retest affected pages
- Re-run automated scans
- Validate fixes with manual testing
Accessibility is ongoing. Schedule regular audits to ensure new content and updates remain compliant.
Why Accessibility Audits Matter in 2026
- Legal Protection: Reduces risk of ADA-related lawsuits
- Better UX: Improves usability for all users
- SEO Gains: Enhances structure, readability, and engagement
- Brand Trust: Demonstrates commitment to inclusivity
- Future-Proofing: Keeps your site aligned with evolving standards
Final Thoughts
Performing a complete accessibility audit in 2026 requires more than a single scan. By combining automated tools, manual testing, and real-world evaluation, you can ensure your website meets WCAG 2.2 and ADA standards while delivering an inclusive experience for all users.
Accessibility audits are not just compliance tasks—they are essential investments in usability, trust, and long-term digital success.
