What is GPTBot?
GPTBot is OpenAI's web crawler that collects data from publicly accessible web pages to improve AI models like ChatGPT, while respecting robots.txt and opt-out preferences. Agent Analytics can track when it visits your website.

Expected Behavior
GPTBot tends to make broad, high-volume sweeps that fetch far more pages per visit than a search crawler. Timing is unpredictable: traffic may remain heavy throughout a collection pass, then stop entirely.

How To Block GPTBot With Robots.txt
Add this rule to your robots.txt file to block GPTBot from accessing your entire 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
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, 25% of the top websites we track currently have robots.txt rules for GPTBot.
Does GPTBot Follow Robots.txt Rules?
Yes. GPTBot is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether GPTBot respects it.
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.
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.
How Can I Tell if GPTBot Is Visiting My Website?
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.
