# Comprehensive Website Accessibility Audit
|
|
|
|
## Instructions
|
|
|
|
In this assignment, you'll conduct a professional-level accessibility audit of a real website, applying the principles and techniques you've learned. This hands-on experience will deepen your understanding of accessibility barriers and solutions.
|
|
|
|
Choose a website that appears to have accessibility issues—this gives you more learning opportunities than analyzing an already-perfect site. Good candidates include older websites, complex web applications, or sites with rich multimedia content.
|
|
|
|
### Phase 1: Strategic manual evaluation
|
|
|
|
Before reaching for automated tools, perform a comprehensive manual assessment. This human-centered approach often reveals issues that tools miss and helps you understand the real user experience.
|
|
|
|
**🔍 Essential evaluation criteria:**
|
|
|
|
**Navigation and Structure:**
|
|
- Can you navigate the entire site using only keyboard (Tab, Shift+Tab, Enter, Space, Arrow keys)?
|
|
- Are focus indicators clearly visible on all interactive elements?
|
|
- Does the heading structure (H1-H6) create a logical content outline?
|
|
- Are there skip links to jump to main content?
|
|
|
|
**Visual Accessibility:**
|
|
- Is there sufficient color contrast throughout the site (minimum 4.5:1 for normal text)?
|
|
- Does the site rely solely on color to convey important information?
|
|
- Do all images have appropriate alternative text?
|
|
- Does the layout remain functional when zoomed to 200%?
|
|
|
|
**Content and Communication:**
|
|
- Are there any "click here" or ambiguous link texts?
|
|
- Can you understand the content and functionality without visual cues?
|
|
- Are form fields properly labeled and grouped?
|
|
- Are error messages clear and helpful?
|
|
|
|
**Interactive Elements:**
|
|
- Do all buttons and form controls work with keyboard alone?
|
|
- Are dynamic content changes announced to screen readers?
|
|
- Do modal dialogs and complex widgets follow proper accessibility patterns?
|
|
|
|
📝 **Document your findings** with specific examples, screenshots, and page URLs. Note both issues and things done well.
|
|
|
|
### Phase 2: Comprehensive automated testing
|
|
|
|
Now validate and expand your manual findings using industry-standard accessibility testing tools. Each tool has different strengths, so using multiple tools gives you complete coverage.
|
|
|
|
**🛠️ Required testing tools:**
|
|
|
|
1. **Lighthouse Accessibility Audit** (built into Chrome/Edge DevTools)
|
|
- Run audit on multiple pages
|
|
- Focus on specific metrics and recommendations
|
|
- Note your accessibility score and specific violations
|
|
|
|
2. **axe DevTools** (browser extension - industry standard)
|
|
- More detailed issue detection than Lighthouse
|
|
- Provides specific code examples for fixes
|
|
- Tests against WCAG 2.1 criteria
|
|
|
|
3. **WAVE Web Accessibility Evaluator** (browser extension)
|
|
- Visual representation of accessibility features
|
|
- Highlights both errors and positive features
|
|
- Great for understanding page structure
|
|
|
|
4. **Color Contrast Analyzers**
|
|
- WebAIM Contrast Checker for specific color pairs
|
|
- Browser extensions for page-wide analysis
|
|
- Test against both WCAG AA and AAA standards
|
|
|
|
**🎧 Real assistive technology testing:**
|
|
- **Screen reader testing**: Use NVDA (Windows), VoiceOver (Mac), or TalkBack (Android)
|
|
- **Keyboard-only navigation**: Unplug your mouse and navigate the entire site
|
|
- **Zoom testing**: Test functionality at 200% and 400% zoom levels
|
|
- **Voice control testing**: If available, try voice navigation tools
|
|
|
|
**📊 Organize your results** by creating a master spreadsheet with:
|
|
- Issue description and location
|
|
- Severity level (Critical/High/Medium/Low)
|
|
- WCAG success criteria violated
|
|
- Tool that detected the issue
|
|
- Screenshots and evidence
|
|
|
|
### Phase 3: Comprehensive findings documentation
|
|
|
|
Create a professional accessibility audit report that demonstrates your understanding of both technical issues and their human impact.
|
|
|
|
**📋 Required report sections:**
|
|
|
|
1. **Executive Summary** (1 page)
|
|
- Website URL and brief description
|
|
- Overall accessibility maturity level
|
|
- Top 3 most critical issues
|
|
- Estimated impact on users with disabilities
|
|
|
|
2. **Methodology** (½ page)
|
|
- Testing approach and tools used
|
|
- Pages evaluated and device/browser combinations
|
|
- Standards evaluated against (WCAG 2.1 AA)
|
|
|
|
3. **Detailed Findings** (2-3 pages)
|
|
- Issues categorized by WCAG principle (Perceivable, Operable, Understandable, Robust)
|
|
- Include screenshots and specific examples
|
|
- Note positive accessibility features you found
|
|
- Cross-reference with automated tool results
|
|
|
|
4. **User Impact Assessment** (1 page)
|
|
- How identified issues affect users with different disabilities
|
|
- Scenarios describing real user experiences
|
|
- Business impact (legal risk, SEO, user base expansion)
|
|
|
|
**📸 Evidence collection:**
|
|
- Screenshots of accessibility violations
|
|
- Screen recordings of problematic user flows
|
|
- Tool reports (save as PDFs)
|
|
- Code examples showing issues
|
|
|
|
### Phase 4: Professional remediation plan
|
|
|
|
Develop a strategic, prioritized plan for fixing accessibility issues. This demonstrates your ability to think like a professional web developer addressing real business constraints.
|
|
|
|
**🎯 Create detailed improvement recommendations (minimum 10 issues):**
|
|
|
|
**For each identified issue, provide:**
|
|
|
|
- **Issue Description**: Clear explanation of what's wrong and why it's problematic
|
|
- **WCAG Reference**: Specific success criteria violated (e.g., "2.4.4 Link Purpose (In Context) - Level A")
|
|
- **User Impact**: How this affects people with different disabilities
|
|
- **Solution**: Specific code changes, design modifications, or process improvements
|
|
- **Priority Level**: Critical (blocks basic usage) / High (significant barrier) / Medium (usability issue) / Low (enhancement)
|
|
- **Implementation Effort**: Time/complexity estimate (Quick win / Moderate effort / Major refactor)
|
|
- **Testing Verification**: How to verify the fix works
|
|
|
|
**Example improvement entry:**
|
|
|
|
```
|
|
Issue: Generic "Read more" link text appears 8 times on homepage
|
|
WCAG Reference: 2.4.4 Link Purpose (In Context) - Level A
|
|
User Impact: Screen reader users cannot distinguish between links when viewed in link list
|
|
Solution: Replace with descriptive text like "Read more about sustainability initiatives"
|
|
Priority: High (major navigation barrier)
|
|
Effort: Low (30 minutes to update content)
|
|
Testing: Generate link list with screen reader - each link should be meaningful standalone
|
|
```
|
|
|
|
**📈 Strategic implementation phases:**
|
|
|
|
- **Phase 1 (0-2 weeks)**: Critical issues that block basic functionality
|
|
- **Phase 2 (1-2 months)**: High-priority improvements for better user experience
|
|
- **Phase 3 (3-6 months)**: Medium-priority enhancements and process improvements
|
|
- **Phase 4 (Ongoing)**: Continuous monitoring and enhancement
|
|
|
|
