Image SEO for AI: Alt Text, Captions and Context
AI can't see your images — it reads the text around them. Here's how to make visual content count for AI visibility.
AI reads text, not pixels
Most crawlers and AI engines understand images through their alt text, captions, file names and surrounding context — not the pixels themselves.
Describe images well
Write descriptive alt text for meaningful images, add captions where useful, use clear file names, and place images near relevant text.
Mark up key images
Use ImageObject in your schema for important visuals (logos, product shots) so engines can associate them with your entity.
