What has to be true before ChatGPT can cite your page?#
Two independent prerequisites, both checkable directly:
OAI-SearchBotis allowed in robots.txt. OpenAI documents this as the specific crawler that determines ChatGPT search inclusion — a page it can't fetch can't appear in a search answer, regardless of how well the content is written. This is a different bot fromGPTBot(training data) andChatGPT-User(real-time, in-conversation fetches); blocking the wrong one is the most common misconfiguration. The full breakdown of what each bot does is on how ChatGPT search works.- The page is indexed by Bing. ChatGPT search draws on the Bing index alongside OpenAI's own crawl. A page absent from Bing is missing one of the two channels ChatGPT search can find it through. See setting up Bing and ChatGPT indexing for the direct-push setup that gets a page into Bing's index without waiting on its normal crawl schedule.
Does serving markdown to bots help you rank in ChatGPT?#
Not by itself, and treating it as the fix is a common overcorrection. Markdown-via-content-negotiation is real — a server can serve a markdown alternate when a request's Accept header asks for text/markdown — but practitioner crawl telemetry (TrustMRR, self-reported, n=1M+ AI bot requests over 30 days, surfaced August 2026) found that AI bots, OpenAI's included, still fetch the plain HTML version of a page roughly half the time, even when a markdown alternate is available. That's corroborating evidence from a single product's traffic, not an OpenAI-published figure, so weight it accordingly — but it points the same direction either way: a site whose HTML is hard to parse or incomplete without JavaScript execution doesn't get solved by adding a markdown format on the side. The HTML response has to work on its own, because roughly half of AI bot requests never ask for anything else. The full reasoning is on how ChatGPT search works.
What content structure gets cited?#
- A direct answer near the top of the relevant section, in a self-contained sentence — the shape most likely to be lifted into a generated response accurately.
- Headings phrased as the actual question a person would ask, not an internal label.
- Accurate information. OpenAI hasn't published a ranking algorithm for ChatGPT search citations, but a page whose content is wrong or outdated is a worse candidate for citation regardless of formatting.
- Content that doesn't require JavaScript execution to appear. This is the same crawlability requirement that governs every AI crawler, ChatGPT's included.
Does Google ranking affect ChatGPT ranking?#
Not directly. Google Search and ChatGPT search run on separate indexes — Google's own index for the former, primarily Bing's index plus OpenAI's own crawl for the latter. A page can rank well in Google while being invisible to ChatGPT search if OAI-SearchBot is blocked or the page hasn't reached Bing's index, and the reverse is also possible. Each needs to be checked on its own terms rather than assumed from the other.
A checklist to work through#
- Confirm
OAI-SearchBotis allowed in robots.txt — check against OpenAI's published IP ranges atopenai.com/searchbot.jsonif you need to verify a request's authenticity. - Confirm the page is indexed by Bing, and push it directly if it's new or recently changed.
- Confirm the page's content is visible to a crawler that executes no JavaScript.
- Lead each relevant section with a direct, self-contained answer.
- Don't treat markdown negotiation as a substitute for fixing the underlying HTML — add it as a supplement if you choose to, not instead.
