How to Rank in ChatGPT: What Is Documented, What Isn't

What OpenAI documents about ChatGPT search and its crawlers, what it does not say, and what a service business can control without promising a mention.

How to rank in ChatGPT is a question no one can answer with a guarantee. OpenAI says ChatGPT ranks search results using multiple factors, but it does not publish the detailed weights or ordering. What OpenAI does publish is how its search crawler works and how ChatGPT treats sources. This guide separates what is documented from what is not, and shows what a service business can control. Our GEO service starts from the same checks.

Key takeaways

OpenAI documents a search crawler named OAI-SearchBot. Sites that opt out of it are not shown in ChatGPT search answers, though they can still appear as navigational links.
OpenAI says ChatGPT ranks results using multiple factors aimed at relevant, reliable information, with no guaranteed placement. It does not publish detailed weights or ordering, so no one can promise a mention.
Whether your robots.txt, host or firewall lets that crawler in is something you control.
ChatGPT may use an approximate location, so state your service area plainly on your pages.
Judge the work by inquiries, and treat any AI "visibility" check as a snapshot, not a score.

How to rank in ChatGPT: is there a ranking at all?

Not one you can look up. OpenAI's help page says ChatGPT may search the web on its own when a question would benefit from current information, and that responses may include citations. It also says ChatGPT ranks search results using multiple factors aimed at relevant, reliable information, with no guaranteed placement. The detailed weights and ordering are not published. The page also warns that search results and citations can be incomplete, outdated or incorrect.

So "rank" is better read as two smaller goals: be eligible to appear, and be a clear, accurate source when ChatGPT looks for one. The first is mostly technical. The second is the same work that helps any search engine, with no guarantee attached.

Which OpenAI crawler affects whether your site can appear?

OpenAI lists several user agents. Three matter for this question, and here is what it says about each, in short:

User agent	What OpenAI says it is for	What it means for you
OAI-SearchBot	Surfacing websites in ChatGPT's search features	A site that opts out is not shown in ChatGPT search answers, though it can still appear as a navigational link. OpenAI recommends allowing it.
GPTBot	Crawling content that may be used to train its generative AI foundation models	Disallowing it indicates the content should not be used for training. OpenAI says each setting is independent of the others.
ChatGPT-User	Certain actions a person takes in ChatGPT and Custom GPTs	OpenAI says it is not used to crawl the web automatically, robots.txt rules may not apply to it, and it is not used to decide whether content appears in Search.

OAI-SearchBot is a crawler: allowing it supports eligibility to appear, but it does not decide whether or where a page is shown, and ChatGPT search also uses partners. Whether to allow GPTBot is a separate choice about training use, and it is a content-policy decision for you to make, not a ranking tactic.

How do you check that you are not blocking ChatGPT search?

Start with the settings you control, in this order:

Open the robots.txt file at the root of your domain. Look for any rule that names OAI-SearchBot, and for any broad rule that could block it by accident.
Ask whoever manages your hosting, CDN or firewall whether automated traffic from OpenAI's published IP address list for OAI-SearchBot is being blocked. OpenAI recommends allowing requests from those ranges.
After a change, allow time. OpenAI says it can take about 24 hours from a robots.txt update for its systems to adjust for search results.
Check your server logs. A user-agent string alone can be spoofed, so a log entry that claims to be OAI-SearchBot is a lead, not proof. Compare the source IP address with OpenAI's current published IP list before concluding the crawler reached the page. Even then, it does not show that the page was cited.
Write down what you changed and the date.

If you are not sure who manages these settings, that is a useful thing to find out. Our guide to an AI-ready website covers the wider checklist.

What does ChatGPT do with a question before it answers?

OpenAI's help page says ChatGPT search sometimes partners with other search providers, and that it typically rewrites a question into one or more targeted queries it sends to them. It also says ChatGPT may use an approximate location based on your IP address, and that including a city, neighborhood or postal code in a question can improve local results.

Two plain takeaways follow. First, the page links privacy statements for partners such as Microsoft and Shopify, which should not be read as a complete list of partners, and it does not explain how pages are picked, so we do not claim to know. Second, pages that clearly state what you do and where you do it give any system, ChatGPT or otherwise, plain facts to work with. We cannot say a clearer page leads to a citation, because OpenAI does not document that link.

What stays unknown?

The OpenAI pages we cite here do not tell site owners:

the detailed weights or order behind how sources are chosen for an answer;
how often OAI-SearchBot revisits a site, or whether you can request a new crawl (the pages we cite do not describe one; other OpenAI documentation may);
whether a specific change to a page will lead to a mention;
how many people click through from ChatGPT to a given site.

Treat a firm promise about any of these as a red flag. If someone offers a number or a timeline, ask where it comes from.

What can a service business do this week?

Keep the list short and honest. These are our suggestions, not OpenAI requirements.

Decide on OAI-SearchBot on purpose, rather than by leaving an old rule in place.
Make sure your main service pages load as normal web pages, with the text visible without a login.
State your services, service area, hours and phone number the same way on your site and your Business Profile. Our guide to NAP consistency shows what to compare.
Answer real customer questions in plain sentences near the top of the page.
Keep dates and details current. OpenAI's own page tells readers to check a source's date, because results can be outdated.

For how this fits with search in general, read GEO vs SEO. It explains what stays the same and what changes.

How do you measure it without inventing numbers?

Use records you can check:

Ask new customers how they found you. Include "ChatGPT or another AI tool" as an option, and write down the answers.
Look at your analytics referral report for visits from chatgpt.com. Referral reports can show some traffic, but how complete they are depends on your setup, the visitor's browser and privacy settings. Treat them as an incomplete indicator, not proof of zero.
If you check how ChatGPT describes your business, save the date, the question and the full answer, then repeat the same questions later.
Compare inquiries before and after a change, and note anything else that changed, such as a new service or a sale.

A mention is not the goal. Calls and booked jobs are.

Frequently asked questions

Should I block GPTBot?▾

That is your decision. OpenAI says GPTBot is used to crawl content that may be used in training its models, and that disallowing it indicates your content should not be used for training. OpenAI also says its search and training settings are independent, so blocking GPTBot is not what controls ChatGPT search.

Does llms.txt help me rank in ChatGPT?▾

The crawler and search pages we read do not tell site owners to publish an llms.txt file. Our llms.txt guide explains what the file is and what it is not.

Can I block ChatGPT-User in robots.txt?▾

OpenAI says ChatGPT-User visits happen when a person asks ChatGPT or a Custom GPT to look at a page, and that robots.txt rules may not apply to those requests. It points to OAI-SearchBot for search opt-outs.

How long after a robots.txt change do the results update?▾

OpenAI says it can take about 24 hours for its systems to adjust for search results. It does not say whether or when your pages would be mentioned.
