Technical SEO for AI search

From Search Visibility Wiki · By the · Published · Last reviewed · How we research

Technical SEO for AI search ensures AI engines can fetch, read and index your pages. Key checks: allow AI search crawlers in robots.txt and at the firewall, serve important content in HTML rather than only through client-side JavaScript, stay indexed, avoid unintended snippet restrictions, and keep structured data matching visible text.

Crawler access

Allow the search agents: OAI-SearchBot,[1] PerplexityBot,[2] Claude-SearchBot,[3] plus Googlebot and Bingbot. Check robots.txt in Search Console.[4] See robots.txt for AI crawlers.

JavaScript rendering

Google processes JavaScript in three phases: crawling, rendering and indexing.[5] Other AI crawlers may not render JavaScript; server-rendered HTML is safest.

Indexing and snippet controls

Pages must be indexed and snippet-eligible for Google AI features.[6] Check with URL Inspection.[7] Notify Bing of changes with IndexNow.[8]

Structured data

Use structured data that matches visible content.[9] See schema markup.

Frequently asked questions

Do AI crawlers render JavaScript?

Google renders JavaScript; for other crawlers, assume HTML is safer.

Does page speed matter for AI search?

No engine documents a speed factor for AI answers; it matters for users and crawling.

Is llms.txt a technical requirement?

No; Google says no special files are needed.
