Definition
Image alt text is descriptive text added to an HTML image element that helps search engines and AI systems understand the content of an image and improves accessibility for screen reader users. Alt text is a valuable text-based signal available to AI crawlers for image content.
Why It Matters for AI Search
AI crawlers process alt text as the text representation of visual content. Images without alt text may be less effectively understood by AI retrieval systems, as they lack explicit textual context — modern AI can still extract some visual information, but alt text significantly improves accuracy and entity signal coverage. Entity-explicit alt text — naming the people, places, products, or concepts depicted — extends the entity signal coverage of a page to its visual content. For brands that communicate through visual formats, properly attributed alt text is a meaningful AI SEO factor.
