To get cited by ChatGPT: allow OAI-SearchBot in robots.txt, get indexed in Bing (ChatGPT Search's primary index), lead pages with a 40-60 word direct answer, back claims with statistics and named sources, add FAQ schema, keep pages fresh, and earn third-party mentions. Citations follow extractability and corroboration - not word count.
ChatGPT Search retrieves via Bing's index (~92%) plus its own OAI-SearchBot, reads candidate pages, and cites the passages it synthesizes from. Two non-obvious facts shape strategy:

User-agent: OAI-SearchBot
Allow: /OAI-SearchBot powers Search; GPTBot is for training and is a separate opt-in. ChatGPT-User handles user-initiated fetches (robots.txt may not apply to those). Allowing OAI-SearchBot is the one that matters for citations. You can confirm your setup with the robots.txt AI checker.
Verify in Bing Webmaster Tools, submit your sitemap, confirm site: returns your pages. This is the highest-leverage, most-overlooked step for ChatGPT.
Put a 40-60 word direct answer at the top of every target page. Models lift self-contained passages; a buried answer doesn't get quoted.
The Princeton GEO study found adding statistics lifts generative visibility up to ~40%, and citing sources/quotations helps too. Replace "many companies" with "37.2% of marketing teams (Omnibound, 2026)."
Question-shaped H2s, comparison tables, numbered steps, definition lists. These are the shapes engines pull cleanly.
FAQPage schema correlates with ~40% higher citation weighting in ChatGPT. Add Article and Organization schema for E-E-A-T signals.
83% of AI citations for commercial queries are pages updated within 12 months. Set a refresh cadence on money pages.
ChatGPT weights third-party validation. Get mentioned on Reddit, G2, and industry roundups. Models treat cross-source consensus as authority.
Run each of these against your own site with the AEO checklist.

No. ChatGPT Search uses OAI-SearchBot. GPTBot only affects whether your content trains future models. Allow OAI-SearchBot for citations; the GPTBot decision is separate. Blocking GPTBot has no effect on whether ChatGPT Search can find and cite your pages.
ChatGPT Search retrieves live results largely from Bing's index (~92% of queries). If Bing hasn't indexed you, ChatGPT often can't find you - regardless of your Google rank. Verify in Bing Webmaster Tools and submit your sitemap as an early, high-leverage step.
Enough to make claims verifiable, with named sources and dates. The GEO study showed statistics were among the strongest levers (~40% visibility lift). Don't fabricate - models and readers penalize unsupported numbers. Quality and attribution matter more than raw quantity here.
Yes - FAQ schema correlates with ~40% higher citation weighting in ChatGPT and helps engines verify E-E-A-T. It's low-cost and high-leverage, and it pairs well with question-shaped headings that make your answers easy for models to lift cleanly.
Often days, since ChatGPT Search re-fetches frequently, provided you're indexed in Bing and OAI-SearchBot is allowed. Freshness compounds: pages updated within 12 months account for the vast majority of AI citations on commercial queries.
