What is GPTBot?
GPTBot is OpenAI's web crawler that collects public web content used to develop and improve its generative AI models. You can set up Agent Analytics to see when GPTBot visits your website.

Why Is GPTBot Visiting My Website?
Your content matched the criteria OpenAI set for a training dataset. GPTBot typically discovers pages through external links, sitemaps, and seed lists rather than because someone selected your site individually.
Should I Block GPTBot?
Block GPTBot if you want more control over whether your work is used for AI training. Allowing it may increase the chance that your brand appears in AI-generated answers, but either choice leaves traditional search rankings unchanged. For context, 23% of the top websites we track currently have robots.txt rules for GPTBot.
How Do I Block GPTBot Using Robots.txt?
Add this rule to your robots.txt file to block GPTBot from accessing your website, or use Automatic Robots.txt to block all AI data scrapers at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
What Traffic Patterns Should I Expect From GPTBot?
GPTBot tends to make broad, high-volume sweeps across many pages. Timing is unpredictable: traffic may remain heavy throughout a collection pass, then stop entirely.
Does GPTBot Follow Robots.txt Rules?
GPTBot is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether GPTBot respects it.
Is GPTBot Used for AI Model Training?
Yes. GPTBot collects web content for use in AI training datasets. Blocking it limits future collection but cannot remove content that was collected previously.
Does Blocking GPTBot Affect AI Search or Citations?
Not directly. Blocking GPTBot limits collection for AI training rather than controlling a live AI search index or citation system.
Does GPTBot Access Private Content?
Not through legitimate access. GPTBot primarily targets public content, but some training-data scrapers also attempt to collect gated or paywalled pages. If content loads without authentication, assume it can be collected.
How Can I Verify a Request From GPTBot?
Agent Analytics tracks visits from GPTBot and every other known AI agent, crawler, and scraper, then authenticates each visit using GPTBot's published verification method. You can also check your server logs for requests whose user-agent string contains "GPTBot". Look for high page counts, short gaps between requests, and deep traversal through linked content. A matching log entry alone is not proof because any bot can claim to be GPTBot.
How Is GPTBot Different From Other OpenAI Agents?
OpenAI operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
