ChatGPT Not Citing Your Website? What OpenAI Says
Why ChatGPT may not cite your site: blocked crawlers, CDN rules, weak pages. What OpenAI's own docs say, five checks you can run today, and what we track.

In August, someone asked r/SEO how to get a site recommended by ChatGPT and Claude. People ask AI tools for "the best hotel/resturant near me," they wrote, "and a few businesses keep getting named while everyone else is invisible." The post had 30 points and 36 comments when we read it. The top reply, at 22 points, opened with "SEO is working." and added that the sources ChatGPT pulls "overlap with what appears in traditional search." Before any of that matters, though, there's a simpler question: can ChatGPT reach your site at all?
OpenAI's three crawlers, and which one matters for citations
OpenAI runs separate bots for separate jobs, and its documentation says "Each setting is independent of the others."
| User agent | What OpenAI says it does | If you block it |
|---|---|---|
| OAI-SearchBot | "used to surface websites in search results in ChatGPT's search features" | Your site isn't shown in ChatGPT search answers, though it "can still appear as navigational links" |
| GPTBot | Crawls "content that may be used in training our generative AI foundation models" | OpenAI reads it as "content should not be used in training"; search is set separately |
| ChatGPT-User | Visits a page when a user's request needs it; "not used for crawling the web in an automatic fashion" | OpenAI says robots.txt rules "may not apply," and it "is not used to determine whether content may appear in Search" |
The citations you see under a ChatGPT answer come from its web search, so OAI-SearchBot is the one to check. A site can block GPTBot to stay out of training and still allow OAI-SearchBot to appear in search. OpenAI's example is exactly that: "a webmaster can allow OAI-SearchBot in order to appear in search results while disallowing GPTBot."
Five checks you can run today
1. Your robots.txt
Open yoursite.com/robots.txt and look for OAI-SearchBot, or a User-agent: * block with Disallow: /. Either can keep you out. If you change it, OpenAI says "it can take ~24 hours from a site's robots.txt update for our systems to adjust."
2. Your CDN or firewall
robots.txt can say yes while your host says no. OpenAI asks sites to allow requests from its published IP ranges. If your site is behind Cloudflare, look at its AI crawler settings: on July 1, 2025, Cloudflare announced it was "changing the default to block AI crawlers." Check whether OAI-SearchBot is in the blocked list for your site.
3. Whether your pages are in search engines at all
OpenAI's help page says ChatGPT search "sometimes partners with other search providers," and the page links Microsoft's privacy statement for those queries. A page that isn't indexed anywhere is a long shot for a citation. If Google doesn't show your page either, start with our guide on why a website isn't showing on Google.
4. Whether the page answers the question in text
OpenAI publishes no list of ranking factors, only that results are ranked "using multiple factors intended to help users find relevant, reliable information." It doesn't ask for special files or markup on either page we read. The practical move is to make sure the answer someone is asking for is written plainly on the page, in text a crawler can read.
5. How you're measuring
One answer on one day proves little. OpenAI's own help page warns that "Search results and citations can be incomplete, outdated, or incorrect." In the r/SEO thread, one reply described a tracking method: "a fixed prompt set rerun on a schedule where I log the cited URLs, not the prose." The same reply separated brand mentions from citations: a mention "is a different event from the model fetching your page as a source." That's one practitioner's method, not a standard, but it's the most checkable one we've seen. The other number you can trust is in your own analytics: visits referred by chatgpt.com.
What we do, and what we can't show yet
We don't have ChatGPT citation numbers for the three sites we run, and we won't estimate them. What we can count, and what goes in your monthly report on our plan, is visits from ChatGPT, Perplexity and Gemini where the browser passes the referrer, next to Google's AI Overviews impressions from Search Console.
Our plan covers the access side in the setup month: a robots.txt that lets the OpenAI, Anthropic and Perplexity crawlers in unless you want them out, and a check that they can reach your pages. Then come the pages themselves, up to 30 articles a month written to answer questions directly. The AI search optimization page lists what we do and what we report. We don't promise citations in AI answers, and our terms say so.
