WCAG Audit Mode — Complete End-to-End WCAG 2.2 Accessibility Audit Plan

Skill Overview

WCAG Audit Patterns provides a website accessibility audit solution based on the WCAG 2.2 standard. It combines automated testing tools with manual verification workflows to help developers identify and fix accessibility violations.

Use Cases

1. Website Accessibility Compliance Audits

Suitable for scenarios requiring a comprehensive accessibility assessment of an existing website, including enterprise websites, e-commerce platforms, education platforms, and other web applications. Through a systematic audit process, this approach identifies WCAG violations and produces remediation recommendations.

2. Legal Compliance and Risk Mitigation

Suitable for organizations that need to meet regulatory requirements such as the ADA (Americans with Disabilities Act) and Section 508 (accessibility requirements for federal agencies), as well as companies preparing for VPAT (Voluntary Product Accessibility Template) certification. It helps reduce legal litigation risk related to accessibility.

3. Accessible Component Development and Optimization

Suitable for integrating accessibility best practices during product development to ensure new components and features comply with WCAG 2.2, and for development teams to fix known accessibility bugs.

Core Features

1. Automated Scanning and Issue Identification

Integrates popular tools such as axe DevTools, Google Lighthouse, and the WAVE browser extension. It performs quick website scans and generates accessibility issue reports, covering common WCAG Level A and AA violations.

2. Manual Validation and User Experience Testing

Complements scenarios that automated tools cannot fully cover, including keyboard navigation smoothness, reasonableness of focus order, screen reader compatibility, and other accessibility experiences that require human judgment.

3. Issue Mapping and Repair Guidance

Precisely maps each detected issue to the corresponding WCAG 2.2 guideline, labels severity levels (low/medium/high/critical), and provides specific code remediation recommendations and references to best practices.

Frequently Asked Questions

How long does a WCAG 2.2 audit take?

The duration depends on the size and complexity of the website. Initial scans for small sites (10–20 pages) can be completed within 1–2 hours, while large e-commerce or SaaS platforms may take several days. A complete audit includes automated detection, manual validation, and remediation verification. It’s recommended to allocate sufficient time and proceed in phases.

Can automated tools detect all accessibility issues?

No. Automated tools can typically detect only about 30–40% of WCAG violations—such as color contrast issues, missing alternative text, and form labeling. Many scenarios, such as determining image meaning, keyboard navigation smoothness, and screen reader experiences, must be verified through manual testing. Therefore, this skill emphasizes a combined approach of automation and manual validation.

How often should WCAG audits be performed?

It’s recommended to conduct audits after every major feature release or page redesign. For industries with high compliance requirements (such as government, healthcare, and education), conduct a full audit quarterly and perform automated quick checks monthly. Integrating accessibility testing into the CI/CD pipeline enables continuous monitoring.
