## Key takeaways

- OAI-SearchBot decides whether a site can appear in ChatGPT search, and OpenAI says sites that block it will not be shown in search answers.
- Blocking GPTBot only opts a site out of model training; OpenAI controls GPTBot and OAI-SearchBot separately.
- seogeoaeo.ai checks robots.txt rules for AI bots, what a page shows without JavaScript, and which bots visit, each as a single run.

Is my site blocking ChatGPT? To find out, look for one name in your robots.txt file: OAI-SearchBot. If a rule disallows it, OpenAI says your pages will not be shown in ChatGPT search answers. The quickest way to be sure is to run your domain through an AI crawler check such as the one at [seogeoaeo.ai](https://seogeoaeo.ai/tools/robots-checker), which lists every rule that blocks an AI bot and the line to change.

## ChatGPT uses more than one bot

OpenAI's crawler documentation lists separate agents, and each one is controlled on its own:

- **OAI-SearchBot** finds pages for ChatGPT search. This is the one that decides whether you can be cited.
- **GPTBot** collects pages that may be used to train OpenAI's models. Blocking it is an opt-out from training, not from search.
- **ChatGPT-User** loads a page when a person asks ChatGPT to. OpenAI says robots.txt rules may not apply to it and that it is not used to decide what appears in search.

So a site can block GPTBot and still show up in ChatGPT search, as long as OAI-SearchBot is allowed. A site owner who blocked GPTBot to shut ChatGPT out has only opted out of training, and the reverse happens too: a broad rule meant for scrapers can catch the search bot by accident.

## Three places a block can hide

**1. robots.txt.** Open `yoursite.com/robots.txt` and look for `User-agent: OAI-SearchBot` or `User-agent: *` followed by `Disallow: /`. Watch the group rule: a bot obeys only the most specific group that names it. If you have a `User-agent: OAI-SearchBot` group, whatever sits under `*` no longer applies to it.

**2. Your firewall or CDN.** A bot-protection setting can return errors to OpenAI's bots even when robots.txt says yes. OpenAI publishes IP lists for OAI-SearchBot, GPTBot and ChatGPT-User so you can allow them on purpose. Your access logs will show whether requests from these bots got a 200 or an error.

**3. JavaScript.** The bot may get in and still find nothing. seogeoaeo.ai notes that most AI crawlers read the HTML the server returns without running scripts. If your text is drawn in by JavaScript, the page can look empty to them.

## A quick test plan

| Check | How | What a problem looks like |
| --- | --- | --- |
| robots.txt rules | seogeoaeo.ai Robots.txt & AI Crawler Checker, 10 credits | A Disallow that matches OAI-SearchBot |
| What the bot can read | seogeoaeo.ai [AI Crawler View](https://seogeoaeo.ai/tools/ai-crawler-view), 8 credits | Main text appears only after JavaScript |
| Whether the bot arrives | seogeoaeo.ai AI Bot Log Analyzer on a pasted log, 8 credits | No OpenAI bot visits, or refused requests |

The robots check also covers GPTBot, ClaudeBot, PerplexityBot and Google-Extended, so you can answer the same question for Claude, Perplexity and Gemini in one pass.

## After you fix it

OpenAI says ChatGPT search can take about 24 hours to adjust after a robots.txt change. Run the check again once the new file is live to confirm the matching rule changed.

You can do the robots.txt part by hand for free if the file is short and has one group. Once there are several groups or wildcards, a checker that names the matching rule saves you from guessing.

## Frequently asked questions

### If I block GPTBot, will ChatGPT stop citing my site?

Not by itself. GPTBot is OpenAI's training crawler. ChatGPT search uses OAI-SearchBot, which you control with its own robots.txt group.

### How long does a robots.txt change take to reach ChatGPT?

OpenAI says its search systems can take about 24 hours to adjust after you update robots.txt.

### Can I stop ChatGPT-User from opening my pages?

OpenAI says robots.txt rules may not apply to ChatGPT-User, because a person asked for the page. It publishes the IP ranges ChatGPT-User uses.
