Getting cited by ChatGPT comes down to two things: letting the right crawler reach your pages, and earning the off-site presence ChatGPT rewards. The crawler that controls whether you appear in ChatGPT's search answers is OAI-SearchBot; if it is blocked, you are invisible there regardless of how good your pages are. Once it can reach you, the pattern in Cited's data is clear. ChatGPT cites a brand's own site in about 84% of responses, but it leans heavily on community and editorial sources, with Reddit as its single most-cited external domain. Being citable means working both sides.
The crawler that matters: OAI-SearchBot
OpenAI runs three crawlers, and telling them apart is the first practical step. The descriptions below are from OpenAI's own bot documentation.
- GPTBot (
GPTBot/1.4) crawls content that may be used to train OpenAI's models. It respects robots.txt. Allowing or blocking it is a training decision, not a citation one. - OAI-SearchBot (
OAI-SearchBot/1.4) surfaces websites in ChatGPT's search features. It respects robots.txt, and sites that opt out will not appear in ChatGPT's search answers. This is the crawler that governs citation. - ChatGPT-User (
ChatGPT-User/1.0) fetches a page when a user's action prompts ChatGPT to visit it. Because these visits are user-initiated, robots.txt rules may not apply.
The takeaway is specific: to be citable in ChatGPT, allow OAI-SearchBot. Many sites block AI crawlers broadly without realising they are also blocking the one that decides whether they appear in ChatGPT answers. You can check which bots can reach your site and confirm OAI-SearchBot is not disallowed.
What ChatGPT favours once it can reach you
Access gets you into the pool. What gets you named is a mix of your own pages and, unusually, your presence off them.
Your own pages still count. ChatGPT cited brands' own sites in most responses in Cited's data, so clear, answer-first, well-structured pages remain the foundation. A page that states a direct answer to a real question, with specific claims rather than marketing prose, is far easier for ChatGPT to lift into an answer.
Off-site presence does heavy lifting. Across every brand Cited measured, Reddit was ChatGPT's most-cited external source, ahead of marketplaces, editorial, and the brands' own sites in aggregate. After Reddit came category and lifestyle editorial and specialist review sites. ChatGPT grounds comparative questions in web search, and community discussion is exactly what those questions call for. This is why a brand can have a strong site and still lose to a competitor that is discussed more across the web. For the full picture of how ChatGPT selects sources, see how ChatGPT cites brands.
The steps that make you citable
In order of impact:
- Allow OAI-SearchBot in robots.txt, and confirm no broad AI-crawler block is catching it. This is the gate; nothing else works until it is open.
- Make your key pages answer-first. Lead with a direct answer to the question a customer would ask, then support it. Extractable structure is what lets ChatGPT quote you.
- Keep your brand entity consistent across your site and the wider web, so ChatGPT resolves you confidently as one entity.
- Build genuine presence where your category is discussed, in communities, editorial, and reviews. This is the off-site work that ChatGPT rewards more than any Google engine, and it is the same foundation as brand authority in AI search.
- Track your presence over time, across several prompts and phrasings, since answers vary between runs and progress shows as a trend, not a single result.
The contrast with Perplexity is useful. Getting cited by Perplexity rewards video and real-time freshness; ChatGPT rewards community and editorial. Covering both is how a brand appears across both engines rather than just one.
Key Takeaways
- OAI-SearchBot is the crawler that controls ChatGPT search citations; if it is blocked in robots.txt, you will not appear in ChatGPT's answers
- GPTBot governs training and ChatGPT-User handles user-initiated browsing; neither is the citation gate, so allow OAI-SearchBot specifically
- ChatGPT cited brands' own sites in about 84% of responses, but Reddit is its single most-cited external source across the brands Cited tracks
- Being citable means both: answer-first, well-structured pages, and genuine presence in the community and editorial sources ChatGPT grounds answers in
- Access and page fixes can surface within a crawl cycle; off-site presence builds over months, so track presence as a trend across prompts and runs
