ChatGPT Search Now Fires Off site: Queries at Scale
Promptwatch found that ChatGPT search now issues site:operator-scoped web queries at scale as part of how it fetches sources for answers.
What it is
A data report from Promptwatch, a Generative Engine Optimization (GEO) company that tracks chatbot responses to prompts across ChatGPT, Claude, and Gemini, covered via Simon Willison's newsletter.
What it does
It documents that ChatGPT search fans out to site:operator-scoped queries against individual domains at scale when answering prompts, rather than relying solely on general web search.
Why it matters
For anyone optimizing content to be cited by AI chat answers, a behavior like this changes what per-domain search visibility actually means, since a page's ranking on a scoped site: query may matter as much as its general search ranking.
How to use it
Check how your own domain performs on scoped site:yourdomain.com queries, not just general search, since that pattern may be what determines whether ChatGPT search surfaces your pages.
