AI search index

A web index built or rented for answer retrieval. OpenAI, Google, Perplexity, and others do not share one pile.

Winning one index is not winning all. Multi-engine sampling exists for this reason.

Freshness SLAs differ. News sites feel it first.

Examples

A page in Google’s index but never fetched by an AI bot. Present in SEO, absent in chat.

How AI systems store pages for later retrieval. Not identical to Google’s index. Different bots, different freshness, different junk filters.

Microsoft’s web index. It has fed various ChatGPT search setups and still matters for Copilot.

Fetching the live web beyond cutoff. How ChatGPT Search and Perplexity stay current — when they bother.

IndexNow and sitemaps help some. There is no universal ping. Links and crawler access still matter.
