Website accessibility isn't just a legal requirement—it's a fundamental aspect of creating an inclusive digital experience. For WordPress site owners, conducting regular accessibility audits with a focus on alt text is crucial for WCAG compliance, improved SEO performance, and reaching a broader audience. This comprehensive WordPress accessibility audit alt text checklist template will guide you through every step of the process.
Why Alt Text Audits Are Critical for WordPress Sites
Alt text serves as the bridge between visual content and users who rely on assistive technologies. According to the World Health Organization, over 1 billion people worldwide live with some form of disability, with visual impairments affecting millions of internet users daily. When your WordPress site lacks proper alt text, you're not only excluding these users but also missing significant SEO opportunities.
Search engines rely on alt text to understand image content, making it a crucial ranking factor. Additionally, with legal requirements becoming increasingly stringent under the Americans with Disabilities Act (ADA) and similar international legislation, proper alt text implementation has become non-negotiable for businesses of all sizes.
The SightSEO WordPress plugin can automate much of this process, but understanding the audit methodology ensures you maintain the highest standards of accessibility compliance.
Pre-Audit Preparation: Setting Up Your WordPress Accessibility Review
Essential Tools and Resources
Before beginning your audit, gather these essential tools:
- Screen reader software: NVDA (free) or JAWS for testing actual user experience
- Browser extensions: axe DevTools, WAVE Web Accessibility Evaluator
- WordPress plugins: WP Accessibility, Accessibility Checker
- Manual testing tools: Keyboard navigation, high contrast mode
- Documentation tools: Spreadsheet software for tracking findings
Establishing Audit Scope and Objectives
Define your audit parameters clearly:
- Which pages and post types to include
- Priority levels for different content areas
- Timeline for completion and remediation
- Success metrics and compliance standards (WCAG 2.1 AA recommended)
The Complete WordPress Alt Text Audit Checklist
Phase 1: Inventory and Discovery
Step 1: Create a comprehensive image inventory
Begin by cataloging all images across your WordPress site:
- Navigate to Media Library and export all media files
- Use plugins like Media Library Assistant to generate detailed reports
- Document image locations, file names, and current alt text status
- Identify images without any alt text attributes
Step 2: Categorize image types and functions
Classify images into functional categories:
- Informative images: Convey specific information or concepts
- Decorative images: Purely aesthetic with no informational value
- Functional images: Serve as links, buttons, or interactive elements
- Complex images: Charts, graphs, diagrams requiring detailed descriptions
- Text images: Images containing readable text
Phase 2: Technical Alt Text Evaluation
Step 3: Assess current alt text quality
For each image with existing alt text, evaluate:
- Accuracy: Does the alt text accurately describe the image content?
- Conciseness: Is it under 125 characters while remaining descriptive?
- Context relevance: Does it fit the surrounding content and purpose?
- Keyword optimization: Does it include relevant keywords naturally?
- Redundancy: Does it avoid repeating nearby text or captions?
Step 4: Identify missing alt text patterns
Look for systematic gaps:
- Specific post types or page templates lacking alt text
- Images added through certain plugins or themes
- User-generated content areas
- Automatically imported or bulk-uploaded images
Phase 3: Content Context Analysis
Step 5: Review alt text in context
Examine how alt text functions within its content environment:
- Read surrounding paragraphs with a screen reader
- Verify alt text adds value without redundancy
- Check for appropriate empty alt text (alt="") on decorative images
- Ensure complex images have accompanying long descriptions
Step 6: Test user experience scenarios
Simulate real user experiences:
- Navigate pages using only keyboard controls
- Use screen reader software to experience content flow
- Test with images disabled in browser settings
- Verify alt text provides equivalent information
Advanced Alt Text Audit Techniques
Automated Scanning and Analysis
While manual review remains essential, automated tools can significantly speed up the initial assessment phase. Consider implementing these advanced techniques:
Database Query Auditing: Use WordPress database queries to identify patterns in alt text usage across your site. This SQL approach can reveal systematic issues:
SELECT post_title, meta_value as alt_text
FROM wp_posts p
JOIN wp_postmeta pm ON p.ID = pm.post_id
WHERE pm.meta_key = '_wp_attachment_image_alt'
AND p.post_type = 'attachment';
Content Analysis Scripting: Develop custom scripts to analyze alt text quality metrics such as length distribution, keyword density, and common phrases that might indicate auto-generated or template-based descriptions.
Specialized WordPress Considerations
Theme and Plugin Compatibility: Different WordPress themes and plugins handle alt text differently. Your audit should account for:
- Custom post types and their image handling
- Page builder compatibility (Elementor, Gutenberg blocks)
- E-commerce product images (WooCommerce specifics)
- Gallery and slider plugin implementations
The SightSEO alt text generator can help identify and resolve these theme-specific issues automatically.
Creating Your Remediation Action Plan
Prioritization Framework
Not all alt text issues carry equal weight. Establish a priority system:
Critical Priority:
- Functional images (buttons, links) without alt text
- Informative images on high-traffic pages
- Images containing text without proper descriptions
- Complex images lacking long descriptions
High Priority:
- Product images in e-commerce sites
- Blog post featured images
- Images in key landing pages
- Infographics and data visualizations
Medium Priority:
- Gallery images with generic alt text
- Archive and category page images
- Social media embedded images
Implementation Timeline and Resource Allocation
Develop a realistic timeline based on your audit findings:
- Week 1-2: Address critical priority items
- Week 3-4: Focus on high-priority pages and posts
- Week 5-8: Systematic review of medium-priority content
- Ongoing: Establish processes for new content
Real-World Case Study: E-commerce Site Transformation
To illustrate the practical application of this checklist, let's examine a detailed case study of a mid-sized WordPress e-commerce site that underwent a comprehensive alt text audit.
Initial Situation Analysis
Site Profile: Online outdoor gear retailer with 2,500 products, 150 blog posts, and approximately 8,000 total images across the WordPress installation.
Pre-Audit Baseline:
- 67% of product images had no alt text
- 23% had generic, template-based alt text ("product image," "photo")
- 10% had descriptive but keyword-poor alt text
- Only 3% met accessibility and SEO best practices
Audit Implementation Process
Phase 1 Discovery (Week 1): Using the inventory checklist, the team identified that WooCommerce product imports had systematically stripped alt text attributes. Custom theme modifications had also bypassed WordPress's native alt text fields in several template files.
Phase 2 Technical Evaluation (Week 2): Manual testing revealed that product category pages were particularly problematic, with screen readers encountering sequences of unlabeled images that provided no context for product differentiation.
Phase 3 Content Analysis (Week 3): The context review showed that many blog post images had alt text that simply repeated the post title, missing opportunities to describe actual image content and include relevant long-tail keywords.
Remediation Strategy and Results
Technical Solutions Implemented:
- Database bulk update to populate missing alt text with product names as temporary measure
