Multimodal Readiness
Learn how GEOAudit checks image alt text, captions, video transcripts, and media schemas for AI multimodal content understanding.
What We Check
GEOAudit checks how well your non-text content is prepared for AI agents that process multiple media types. We validate image alt text descriptiveness and quality, image captions, figure elements with figcaption, video transcript availability, audio transcript availability, ImageObject and VideoObject schema markup, responsive image implementation (srcset), SVG accessibility (title and desc elements), and overall media annotation quality. Multimodal AI agents need text annotations to understand visual and audio content.
How We Score
Multimodal Readiness carries a 3% weight in the overall score — the lowest weight, reflecting that it's important but secondary to text-based signals. Each check produces pass, warn, or fail. Key assessments include: alt text coverage and quality, caption presence, video/audio transcript availability, media schema markup, and responsive image implementation.
Why It Matters
AI is becoming increasingly multimodal — systems like GPT-4V, Gemini, and Claude can process images, video, and audio. However, they still rely heavily on text annotations (alt text, captions, transcripts) to understand media context. Pages with well-described visual content give AI agents richer information to work with. As AI becomes more multimodal, properly annotated media will become a significant competitive advantage for AI discoverability.
How to Improve
Write detailed, descriptive alt text for all meaningful images — describe what the image shows and why it matters. Add captions to images using <figure> and <figcaption>. Provide transcripts for all video and audio content. Add ImageObject schema for key images and VideoObject schema for videos. Implement responsive images with srcset for optimal delivery. Add title and desc elements to SVGs. Consider creating text summaries of infographics and complex diagrams.
Frequently Asked Questions
How descriptive should alt text be for AI?
Alt text should describe what the image shows specifically, not just generically. Instead of 'graph', write 'Line graph showing website traffic growing from 10K to 50K monthly visits over 12 months'. More descriptive alt text gives AI agents richer context to work with.
Do AI agents use video transcripts?
Yes — most AI agents cannot process video directly but can read transcripts. Providing text transcripts for video content makes that information discoverable and citable by AI. Without transcripts, video content is invisible to most AI systems.
What is ImageObject schema?
ImageObject schema (Schema.org/ImageObject) provides structured metadata about images including name, description, contentUrl, and license. It helps AI agents understand the purpose and content of images beyond what alt text provides.
Is multimodal readiness important today?
It's becoming more important as AI systems add vision and audio capabilities. While text-based signals currently dominate AI discoverability, properly annotated media content gives you a head start as multimodal AI becomes the norm.
