OAI-SearchBot and GPTBot serve different purposes. If your goal is visibility in ChatGPT search, review OAI-SearchBot access separately from your policy on training crawlers. Allowing one does not require allowing the other.
OpenAI's crawler documentation describes these controls independently. OAI-SearchBot is used for ChatGPT search; GPTBot may gather content for model training. Neither an allow rule nor a successful request guarantees a citation.
Start with a written access policy
Before editing robots.txt, write down what the site should permit.
For example, a team may want its public documentation available in ChatGPT search while declining GPTBot training crawls. That is a policy example, not advice to expose private pages.
List the public sections covered by that decision. Keep account pages, customer data, and private documents behind their existing access controls. Robots.txt is not an authentication system.
An access review should make the intended public content reachable without weakening the rules that protect private content.
Understand what the rules say
For the example policy above, a robots.txt fragment could look like this:
User-agent: OAI-SearchBot
Allow: /
User-agent: GPTBot
Disallow: /
This fragment illustrates separate user-agent groups. It is not a complete configuration for every website.
Review the site's existing rules before using it. Preserve restrictions that apply to private or unsuitable paths, and check whether more specific groups already exist. An isolated example cannot show all the rules on your site.
Also inspect the hostname being served. Rules on one host aren't evidence that another host has the same configuration.
Check the request path beyond robots.txt
A crawler can encounter a block elsewhere in the request path: a firewall rule, an edge challenge, an error, or a redirect that never reaches the intended page.
OpenAI recommends allowing OAI-SearchBot and its published IP ranges for search access. Use the current official list when investigating identity. A user-agent string alone can be copied by someone else.
Ask the person who manages the edge configuration to review the specific rule. Avoid a broad “allow all bots” change.
Keep a short record of the public URL, observed response, applicable rule, and evidence used to identify the request. If you don't have logs or a verified request, write “not checked” rather than “crawler access confirmed.”
Don't confuse a user fetch with a search crawl
OpenAI also documents ChatGPT-User for requests initiated by a user. That role differs from automated search crawling. A page opening successfully during a chat does not establish that OAI-SearchBot can crawl it.
Keep those tests separate. “The assistant fetched this URL” and “the search crawler has access to this section” answer different questions.
The same care applies across providers. Anthropic's bot documentation lists ClaudeBot, Claude-User, and Claude-SearchBot with different roles. Don't copy OpenAI's names into a policy intended for Claude.
Verify the change before calling it done
After an authorized configuration change, inspect the served robots.txt on the intended host. Check a representative public page and confirm that existing private access still works as intended.
Have another person review the policy against the rules actually served. Record what changed and when, so later traffic investigations have context.
Then return to content. Search access doesn't replace clear answers, useful evidence, or a page that resolves a reader's question.
Treat crawler access as one condition you can review. Treat citations as a separate outcome you observe. That distinction keeps a technical fix from turning into an unsupported marketing promise.
