Ensure your website is inclusive and user-friendly with our detailed accessibility audit guide. Learn how to identify and fix barriers, meet WCAG compliance standards, improve user experience, and expand your audience while boosting overall site performance.
Ensuring your website is accessible is not just a legal or ethical obligation—it’s also a way to provide a better user experience for everyone. Conducting an accessibility audit allows you to identify and address barriers that might prevent individuals, including those with disabilities, from using your website effectively.
In this comprehensive guide, we will walk you through the steps to conduct a successful accessibility audit, helping you meet compliance standards, improve user experience, and boost your website’s overall performance.
Why Is an Accessibility Audit Important?
An accessibility audit evaluates how easy it is for individuals, especially those with disabilities, to interact with your website. According to the Web Content Accessibility Guidelines (WCAG), websites should be Perceivable, Operable, Understandable, and Robust (POUR). Achieving these principles ensures your site is inclusive and user-friendly for all.
Here are some key benefits of conducting an accessibility audit:
Improved User Experience: An accessible website caters to everyone, including people with visual, hearing, mobility, or cognitive impairments.
Compliance with Regulations: Many countries have laws, like the ADA (Americans with Disabilities Act) and Section 508, that require websites to be accessible.
Wider Audience Reach: By removing barriers, you can engage a broader audience and retain visitors.
SEO Benefits: Search engines reward accessible websites, as they are typically easier to crawl and index.
Step 1: Define the Scope and Goals of Your Audit
Before diving into an accessibility audit, define the scope and goals:
Which Pages Will You Test? Start with high-traffic pages, landing pages, and core navigation areas like the home page, contact page, and forms.
What Standards Will You Follow? Decide if you’ll align with WCAG 2.1 at Level A, AA, or AAA.
What Tools Will You Use? Identify software and manual methods to test accessibility.
Example: If your goal is WCAG 2.1 Level AA compliance, tools like WAVE, axe DevTools, and Google Lighthouse will be instrumental.
Pro Tip: Document your findings as you progress. Organize your notes in a spreadsheet or audit tool.
Step 2: Use Automated Accessibility Testing Tools
Automated tools can quickly identify common accessibility issues. While they can’t replace manual testing, they are a great starting point.
Recommended Tools for Automated Testing:
WAVE (Web Accessibility Evaluation Tool): Identifies errors like missing alt text or improper color contrast.
axe DevTools: A browser extension that highlights accessibility violations.
Google Lighthouse: Provides an accessibility score and actionable suggestions.
Siteimprove: An advanced tool that performs a comprehensive audit.
How to Use These Tools:
Install a browser extension like WAVE or axe DevTools.
Open your webpage in the browser.
Run the tool and review the errors flagged.
Take note of common issues like:
Missing alternative text for images
Improper headings hierarchy (H1, H2, H3, etc.)
Low color contrast between text and background
While automated tools provide quick insights, they only catch around 30-40% of accessibility issues. This is where manual testing comes into play.
Step 3: Conduct Manual Accessibility Testing
Manual testing allows you to identify issues automated tools might miss. Follow these steps to ensure comprehensive testing:
Keyboard Navigation Testing:
Navigate your site using the Tab key.
Verify that links, buttons, and forms can be accessed and activated without a mouse.
Check for visual focus indicators.
Screen Reader Testing: Use screen readers like NVDA (free for Windows) or VoiceOver (built into macOS).
Listen to how content is read aloud.
Ensure alternative text for images is descriptive and accurate.
Verify that page headings and links make sense when read linearly.
Color Contrast Testing:
Use tools like Contrast Checker or WAVE to ensure a contrast ratio of at least 4.5:1 for text.
Avoid relying solely on color to convey meaning (e.g., red text for errors).
Forms and Interactive Elements:
Check that all form fields have labels.
Verify error messages are clear and accessible.
Ensure buttons and controls are operable without a mouse.
Step 4: Evaluate Multimedia Accessibility
For websites with multimedia elements like videos, audio files, and animations, it’s essential to provide accessible alternatives.
Key Requirements:
Video Content: Add captions, transcripts, and audio descriptions.
Audio Content: Provide text transcripts.
Animations: Ensure they are not disruptive and offer a pause or stop button.
Use tools like YouTube’s auto-captioning feature or third-party services to create accurate captions and transcripts.
Step 5: Test Your Website on Multiple Devices and Browsers
People access websites using various devices, browsers, and assistive technologies. Testing across these platforms ensures a consistent experience.
Checklist for Testing:
Test on desktop, tablets, and mobile devices.
Use popular browsers like Chrome, Firefox, Safari, and Edge.
Ensure compatibility with assistive technologies like screen readers and voice control software.
Step 6: Compile and Prioritize Issues
After conducting both automated and manual testing, compile your findings:
Document Issues: Use tools like Google Sheets or project management software to organize your audit results.
Categorize Problems: Prioritize based on severity:
Critical: Issues preventing users from accessing key content or actions.
High: Errors impacting the user experience but not blocking access.
Medium/Low: Minor errors that need addressing but are less urgent.
Provide Solutions: Suggest clear fixes for each issue, such as:
Adding alt text for all images
Improving heading structures
Fixing broken links
Step 7: Implement Fixes and Re-Audit
Once issues have been identified and prioritized, work with your developers, designers, or content team to implement fixes.
Retest: After changes are made, run automated and manual tests again to confirm improvements.
Continuous Monitoring: Accessibility isn’t a one-time task. Regularly monitor your website to maintain compliance as you add new content or features.
Step 8: Educate Your Team and Create an Accessibility Policy
To ensure long-term accessibility:
Train your team on accessibility best practices.
Integrate accessibility into your design, development, and content processes.
Create a clear Accessibility Policy that outlines your commitment and standards.
