No. Blocking GPTBot does not change how Google ranks your pages. GPTBot belongs to OpenAI, and Googlebot is a different crawler that follows its own rules. The risks to watch for are different: a sloppy rule that blocks Googlebot too, and the loss of visibility in other AI products.
Does Blocking GPTBot Hurt Your Google Ranking?
Short answer no, plus the one robots.txt mistake that can.
The short answer
Blocking GPTBot does not affect your Google ranking, because GPTBot is OpenAI's crawler and Googlebot follows separate rules. What can hurt is a broad wildcard rule that also blocks Googlebot. Blocking OpenAI's search bot can also reduce visibility in ChatGPT.
Bottom lineName the crawlers you mean to block, and avoid wildcard rules unless you want to block everything.
On this page
A plain-text file at the root of a site that tells crawlers which parts of it they may or may not request. It is a request, not a security control.
Google Search is built from pages fetched by Googlebot. GPTBot is run by OpenAI and has no part in that. A robots.txt rule that names GPTBot applies to GPTBot only:
User-agent: GPTBot
Disallow: /
Googlebot keeps crawling as before, because nothing in that rule mentions it. For the exact rules, see how to allow or block GPTBot in robots.txt.
Where people do hurt their Google ranking
The danger is a rule broader than you meant. A wildcard group applies to every crawler that does not have its own group, and that includes Googlebot:
User-agent: *
Disallow: /
This blocks Google as well, because Googlebot has no group of its own to follow instead. Google's documentation says a crawler follows only the single most specific group that matches it, so a separate group for Googlebot overrides the wildcard for Googlebot. If Google cannot crawl your pages, their visibility in search can suffer. Edits made through plugins, hosts or CDNs sometimes produce a rule like this without you noticing. If you think that has happened, see robots.txt blocking AI bots by accident.
What about Google-Extended
Google-Extended is a control token, not a crawler. It lets you opt your content out of use for Google's Gemini models. Google states that it does not affect inclusion in Google Search or ranking.
What blocking GPTBot does cost
OpenAI says disallowing GPTBot signals that your content should not be used to train its models. It does not cover OAI-SearchBot, the crawler for ChatGPT search, or ChatGPT-User, which fetches pages when a person asks. OAI-SearchBot needs its own rule, and blocking it can keep your pages out of ChatGPT search answers. OpenAI says robots.txt rules may not apply to ChatGPT-User. For every crawler name, see the AI crawler list for robots.txt.
Check your result
After editing robots.txt, run your domain through the AI crawler checker to see which AI crawlers are blocked and whether a wildcard rule is the cause. For wider search health, the SEO checker is a quick second look.

GPTBot rule
It affects OpenAI's training crawler only, not Google.
What we did: Block GPTBot in robots.txt if you want to opt out of training, since Googlebot is unaffected.

Wildcard disallow
It applies to every crawler without its own group, including Googlebot.
What we did: Remove the wildcard block or add a separate group for Googlebot.
- !AEO
OAI-SearchBot rule
Blocking it can reduce visibility in ChatGPT search.
What we did: Leave OAI-SearchBot allowed if you want to appear there.

FAQ
No. GPTBot is OpenAI's crawler and has no role in Google's index or ranking.
Yes, if a rule blocks Googlebot, such as a wildcard group that disallows the whole site.
Google says it does not. It only controls use of content for Gemini models.
Not by itself, because search uses OAI-SearchBot. Blocking that one can reduce visibility.
