How to Let ChatGPT's Search Crawler Read Your Website (OAI-SearchBot vs GPTBot)

If your website blocks OAI-SearchBot, it can't appear in ChatGPT search answers. How to check your robots.txt, what GPTBot does, and the settings that block bots by accident.

Before any other advice about getting named by ChatGPT, check one thing: can ChatGPT's search system actually read your website? OpenAI says sites that block its search crawler won't appear in ChatGPT search answers. It's the cheapest fix in this whole subject, and it takes about ten minutes to check.

Allowing the crawler doesn't guarantee a recommendation. It only makes your site eligible. This guide explains OpenAI's three bots in plain English, shows what a safe robots.txt looks like, and lists the settings that block crawlers without the owner knowing.

The three OpenAI bots

OpenAI's bot documentation lists three:

Bot What it does What blocking it does
OAI-SearchBot Finds and surfaces websites in ChatGPT's search features Your site won't appear in ChatGPT search answers (it may still show as a plain link)
GPTBot Collects content that may be used to train OpenAI's models Tells OpenAI not to use your content for training. It does not control whether you appear in search
ChatGPT-User Visits a page when a user asks ChatGPT to, for example, open it OpenAI says robots.txt rules may not apply to it, and it doesn't decide whether you appear in search

The detail that trips people up: blocking GPTBot is a training choice, not a visibility choice. A contractor can say no to training and still be visible in search by allowing OAI-SearchBot.

OpenAI says changes to robots.txt can take about 24 hours to take effect for search, and it also recommends allowing its published IP ranges.

Check your robots.txt in two minutes

  1. In your browser, go to yourwebsite.com/robots.txt. Every website has one (if you get an error page, you probably don't block anything this way).
  2. Look for lines naming OAI-SearchBot, GPTBot or PerplexityBot. Pay attention to any Disallow: / that follows User-agent: *, which blocks every bot that isn't named separately.
  3. If you see Disallow: / under OAI-SearchBot, ChatGPT search can't read your site.

A safe setup for most local businesses looks like this:

User-agent: OAI-SearchBot
Allow: /

User-agent: PerplexityBot
Allow: /

User-agent: Googlebot
Allow: /

If you want to opt out of model training but stay visible in search, add a block for GPTBot:

User-agent: GPTBot
Disallow: /

Bots follow the most specific group that names them, so an explicit OAI-SearchBot group usually overrides a general block. If you're not sure, send the file to whoever built your site and ask: "Does this allow OAI-SearchBot and PerplexityBot?"

Where accidental blocks come from

Even if your robots.txt is fine, something else on the way to your site may turn bots away:

None of these is unusual. Our free scan includes a website check for AI-bot blocking, because it's a common finding.

If you use a website builder or an agency

Most small contractors don't edit files directly. A few practical routes:

Give the crawler something worth reading:

FAQ

Should I block GPTBot? That's your choice about training. It doesn't affect whether you appear in ChatGPT search, which depends on OAI-SearchBot.

I can't edit robots.txt. What now? Most website platforms have a settings page for it, or your web person can edit it. Ask for "allow OAI-SearchBot and PerplexityBot."

How do I know it worked? Wait a day, then ask ChatGPT a customer question in your area and see which sites it cites. Our five-minute test shows how.
