How do I check if ChatGPT knows about my website?

TL;DR

Ask ChatGPT (or Perplexity, Google AI Overviews, Claude) the kinds of questions a buyer of your service would ask, then see whether your business appears as a citation. The fastest way is the free AI Search Check tool at rebuilt.studio/ai-search-check, it runs six buyer-side queries shaped to your industry and metro across ChatGPT search and Perplexity in about 30 seconds and produces a public report.

There are two ways to find out: the manual way and the tool way. The manual way: open ChatGPT, set the chat to use search (the globe icon below the prompt), and ask three or four questions a buyer in your area would type. "Best HVAC contractor in [your city]." "Where can I get a CNC part machined in [your metro]?" Read the response carefully, does your business name appear in the answer? Is it cited as a source under the response?

The tool way is faster and reproducible. The Rebuilt Studio AI Search Check pastes your URL, derives the six buyer-side queries from your homepage, runs them against ChatGPT search and Perplexity in parallel, and returns a public scoreboard: which engines cited you, which queries you appear in, who got cited instead, and what structural signals are missing on your site that AI engines look at.

A common gotcha: ChatGPT without search enabled draws from its training cutoff, which is six to nine months out of date. If your site went live last quarter, it may not be in the training set yet, but the search-enabled version of ChatGPT crawls the live web and will find a properly-indexed site. Always check with search on.

Common follow-ups

What if my site isn't cited at all?

It usually means one of three things: your site is missing the structural signals AI engines look for (LocalBusiness JSON-LD, FAQPage schema, llms.txt, an HTML-readable services list); your content is image-heavy or PDF-locked; or your site is too new to have been crawled. The AI Search Check report breaks down which it is.

How often should I re-run the check?

Every 30–60 days is enough for most small businesses. AI engines re-crawl on roughly that cadence; running daily produces noise without signal. Run after you ship a structural change (added FAQPage schema, added llms.txt, fixed mobile speed) to see the lift.
