How to get cited by ChatGPT
Two things have to be true for ChatGPT to name your site: its crawlers must be allowed to read you, and what they read must be worth quoting. This page covers both, starting with the part most sites get wrong by accident.
Know OpenAI's three crawlers
OpenAI publishes the user agents it uses, and you control each one in your robots.txt. They do different jobs, so blocking the wrong one quietly costs you visibility.
- GPTBot is OpenAI's general web crawler. It gathers content that can improve the models.
- OAI-SearchBot is used to surface and link sites inside ChatGPT search results. This is the one that matters most for being cited.
- ChatGPT-User fetches a specific page when a user's prompt triggers a live visit to it.

Allow them explicitly
If you want to be eligible for ChatGPT citations, make sure none of these are blocked. A minimal, explicit allowance in robots.txt looks like this:
User-agent: OAI-SearchBot
Allow: /
User-agent: ChatGPT-User
Allow: /
User-agent: GPTBot
Allow: /If you would rather not contribute to model training but still want to be found in ChatGPT search, allow OAI-SearchBot and ChatGPT-User and disallow GPTBot. The point is to choose on purpose. A blanket block, often copied from a template, is how good sites disappear from AI answers without realising.
Be worth quoting
Access only makes you eligible. To actually be named, give the model clean material to lift:
- Answer the real question in the first two sentences of a section, then expand underneath.
- Use question-shaped headings that match how buyers ask.
- Add schema.org structured data so a machine can parse what your page is.
- State clearly who you are and what you do, so you are described accurately rather than guessed at.
- Publish honest comparison pages, because ChatGPT reaches for those when a buyer asks how options differ.
Check where you stand
Start by seeing what you already allow and how quotable your pages are. The free Avantas audit reports which AI crawlers you permit and scores the signals above. For the broader picture, read answer engine optimization explained.
Common questions
Does allowing GPTBot guarantee ChatGPT will cite me?
No. Allowing the crawlers is necessary but not sufficient. It makes you eligible to be read and quoted. Being cited still depends on having clear, trustworthy, relevant content for the question being asked.
Will blocking GPTBot hurt my visibility in ChatGPT?
It can. If you block the crawlers OpenAI uses to read and surface sites, you remove yourself from that path entirely. Some sites block GPTBot to prevent training use while still allowing search crawlers. Decide deliberately rather than by accident.
How do I check what I currently allow?
Open yourdomain.com/robots.txt in a browser and look for rules targeting GPTBot, OAI-SearchBot and ChatGPT-User. The free Avantas audit also reports which AI crawlers your site allows or blocks.
