Accessibility
Learn how GEOAudit checks accessibility features that also improve AI agent content parsing. Alt text, ARIA, landmarks, lang attribute, and more.
What We Check
GEOAudit evaluates accessibility features that directly impact AI agent content parsing. We check for HTML lang attribute, image alt text presence and quality, ARIA landmark roles, skip navigation links, heading accessibility, form labels, color contrast indicators, keyboard navigation support, and proper link text (avoiding 'click here' patterns). These WCAG criteria overlap significantly with what AI agents need to understand your content.
How We Score
Accessibility carries a 7% weight in the overall score. Each check produces pass, warn, or fail. Key checks include: HTML lang attribute, alt text coverage, ARIA landmarks, skip navigation, descriptive link text, and form accessibility. Images without alt text are marked as fail since AI agents cannot interpret images without text descriptions.
Why It Matters
Accessibility and AI readability are deeply connected. The HTML lang attribute tells AI agents what language your content is in. Alt text provides AI with descriptions of visual content. ARIA landmarks help AI navigate page structure. Skip navigation and proper heading hierarchy enable AI to jump directly to main content. Pages built with accessibility best practices are inherently more parseable by AI agents.
How to Improve
Set the lang attribute on your HTML element (e.g., lang='en'). Add descriptive alt text to all meaningful images — describe what the image shows, not just 'image' or 'photo'. Add ARIA landmark roles or use semantic HTML5 elements. Include a skip navigation link for keyboard and AI crawler access. Use descriptive link text instead of 'click here' or 'read more'. Ensure all form inputs have associated labels.
Frequently Asked Questions
How does accessibility overlap with AI readability?
Many accessibility features directly help AI agents: alt text describes images, lang attribute identifies language, ARIA landmarks define page structure, and semantic heading hierarchy explains content relationships. Building for accessibility inherently builds for AI.
What makes a good alt text for AI discoverability?
Good alt text describes what the image actually shows in a concise, specific way. Instead of 'chart', write 'Bar chart showing 40% increase in organic traffic from Q1 to Q4 2025'. AI agents use alt text to understand and potentially cite visual content.
Is the lang attribute really important?
Yes — the HTML lang attribute tells AI agents what language your content is in, which affects text processing, translation, and language-specific AI models. Missing lang can cause AI to misprocess your content entirely.
Do ARIA landmarks help AI crawlers?
ARIA landmarks (or their semantic HTML equivalents) help AI agents identify page regions: main content, navigation, sidebar, etc. This allows AI to focus on the primary content rather than parsing navigation menus or footers.
