How ChatGPT finds and cites brands
Checked against ChatGPT documentation on November 4, 2026
ChatGPT can answer from what its model already learned, or it can search the web. For a brand, those are different problems. Your place in a model’s training data is mostly out of your hands. Being reachable by search is something you can check today.
The three OpenAI crawlers
OpenAI runs separate crawlers, and each setting is independent of the others.
- OAI-SearchBot surfaces websites in ChatGPT’s search features. OpenAI says sites opted out of it won’t be shown in ChatGPT search answers, though they may still appear as navigational links.
- GPTBot collects content to improve OpenAI’s foundation models. Blocking it signals that your content shouldn’t be used for training.
- ChatGPT-User handles certain actions a person starts in ChatGPT. OpenAI says it isn’t used for automatic crawling, and doesn’t decide whether content can appear in search. Robots.txt rules may not apply to it, because a person started the request.
So you can block GPTBot and still allow OAI-SearchBot. Check which one you’ve actually set. OpenAI says a robots.txt change can take about 24 hours to reach its search systems.
What to check first
- Read your robots.txt and confirm OAI-SearchBot isn’t blocked, either by name or by a
User-agent: *rule. The free AI crawler checker does this for you. - Check your CDN or firewall too. Robots.txt is only a request, and a bot block at the network level won’t show up there.
- Decide on GPTBot as a separate choice about training.
How answers carry sources
In OpenAI’s API, web search answers include inline citations by default, and a separate sources list holds every URL the model consulted. That list is usually longer than the citations. In other words, a page can be read without being cited, so being cited is the narrower signal.
Why one check isn’t enough
Ask ChatGPT the same question twice and you can get two different answers, so a single search proves very little. Measure how often you appear across repeated runs, and read the range, not one result.
How Ocita measures it
Ocita sends your prompts through OpenAI’s API with web search on, up to 5 times a week, then records mentions, position and citations. These API answers can differ from the consumer app, which adds memory and personalization.
