GPTBot

recommended: observe
Operated by OpenAI ai crawler

GPTBot is used to crawl content that may be used in training OpenAI's generative AI foundation models

What it does

AI data scrapers systematically crawl websites to collect training data for machine learning models. Unlike search engine crawlers that index for retrieval, these scrapers download content specifically for model training. Their crawling patterns are typically opaque. Operators rarely disclose site selection, frequency, or priorities. Scrapers may crawl more aggressively than traditional search engines, and the collected data becomes part of training datasets with limited transparency about attribution or usage.

How to identify it

User-agent contains any of:

  • GPTBot
  • Mozilla

Example user-agent string:

Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; GPTBot/1.0; +https://openai.com/gptbot)

robots.txt

Well-behaved crawlers honor robots.txt. To control GPTBot:

Allow full access

User-agent: GPTBot
Allow: /

Block entirely

User-agent: GPTBot
Disallow: /

Grey-area scrapers ignore robots.txt. Botscope enforces your policy at the edge or origin regardless — see how →

FAQ

Should I Block GPTBot?

Consider your priorities. GPTBot collects content for training machine learning models. While this content is publicly accessible, you may want to block it if you're concerned about attribution, compensation, or how your creative work might be used in AI systems or generated outputs.

How Do I Block GPTBot?

If you want to, you can block or limit GPTBot's access by configuring user agent token rules in your robots.txt file. The best way to do this is using Automatic Robots.txt, which update automatically as new agents are discovered. While the vast majority of agents operated by reputable companies honor these robots.txt directives, bad actors may choose to ignore them entirely. In that case, you'll need to implement alternative blocking methods such as firewall rules or server-level restrictions. You can verify whether GPTBot is respecting your rules by setting up Agent Analytics to monitor its visits to your website.

Will Blocking GPTBot Hurt My SEO?

Blocking AI data scrapers has minimal direct SEO impact since these tools don't contribute to search engine indexing. However, if your content is used to train models that power AI search engines, blocking scrapers might reduce your representation in AI-generated responses, potentially affecting future discoverability.

Does GPTBot Access Private Content?

AI data scrapers typically focus on publicly available content for training data collection. However, some may attempt to access password-protected areas, API endpoints, or content behind paywalls. The scope varies widely depending on the operator's goals and technical sophistication. Most respect authentication barriers, but some may use techniques to bypass access controls.

How Can I Tell if GPTBot Is Visiting My Website?

Setting up Agent Analytics will give you realtime visibility into GPTBot visiting your website, along with hundreds of other AI agents, crawlers, and scrapers. This will also let you measure human traffic to your website coming from AI search and chat LLM platforms like ChatGPT, Perplexity, and Gemini.

Why Is GPTBot Visiting My Website?

GPTBot likely found your site through systematic web discovery methods like following links from other indexed sites, processing sitemaps, or using seed URLs from publicly available website lists. Your site may have been selected because it contains the type of content useful for training AI models.

How Can I Authenticate Visits From GPTBot?

Agent Analytics authenticates agent visits from many agents, letting you know whether each one was actually from that agent, or spoofed by a bad actor. This helps you identify suspicious traffic patterns and make informed decisions about blocking or allowing specific user agents.
