What is GPTBot and what does it do with my content?

GPTBot is OpenAI's web crawler. It collects public web material that may be used to train future models, identifies itself in server logs, and respects robots.txt. It is separate from OAI-SearchBot, which handles ChatGPT search, and ChatGPT-User, which fetches on a person's request. ye5's GEO Web audit measures what crawlers like it can read across your site.

What does GPTBot do with what it reads?

GPTBot crawls public pages and collects material that may be used to train future versions of OpenAI's models. What it reads today can shape how a later model describes your brand. Training directives govern future collection; they do not erase existing datasets or guarantee a change in any model version.

How is GPTBot different from OAI-SearchBot and ChatGPT-User?

OpenAI runs three agents for three jobs. GPTBot handles training collection, OAI-SearchBot handles ChatGPT search, and ChatGPT-User handles user-triggered fetching. Blocking GPTBot does not control the other two, and robots.txt rules may not apply to ChatGPT-User.

—GPTBot: crawls broadly; collects material for future training; no single user behind the request.
—OAI-SearchBot: crawls for ChatGPT search; blocked independently of GPTBot.
—ChatGPT-User: fetches on demand; triggered by a live conversation.

How do you verify a GPTBot request?

—Match the GPTBot user-agent string in your server or CDN logs.
—Confirm the request against OpenAI's official published bot IP ranges.

Requests prove neither training nor citation. A log line shows that a fetch happened, nothing more. What matters is whether GPTBot can reach the pages that represent your brand in the first place.

Should you allow GPTBot to crawl your site?

Decide on your content policy. Allow GPTBot where you accept your public content being collected for future training, and restrict it where you do not. Blocking GPTBot does not prevent brand mentions or control the separate search and user-fetch agents, which may still retrieve your own pages. Should I block AI crawlers from my site? works through the tradeoff in full.

FAQ

How do I see GPTBot in my logs?

Search your server or CDN logs for the GPTBot user agent string, then confirm the visit against OpenAI's official published bot IP ranges before you count it.

Does my content need to be in the initial HTML for GPTBot?

Keep essential facts in the initial HTML. Fetcher capabilities vary between systems, so content that appears only after scripts run may not reach every one of them.

If I block GPTBot, does ChatGPT stop mentioning my site?

No. Blocking GPTBot affects collection for future training and does not control OAI-SearchBot or ChatGPT-User. Robots.txt rules may not apply to ChatGPT-User, and other sources can still describe you regardless.
