# CCBot

> CCBot is Common Crawl's crawler for collecting pages that may be used to train AI models. Here's how to recognize it and check a request really is it.

## CCBot facts

- **Operator:** Common Crawl
- **Type:** Crawler
- **Why it fetches:** Collects training data
- **User agent contains:** `CCBot`
- **Verified by:** published IP ranges
- **Operator's documentation:** [commoncrawl.org/ccbot](https://commoncrawl.org/ccbot)

## How to tell a real CCBot from an impostor

Anyone can put "CCBot" in a user agent. What can't be faked is below.

- **Check the address.** Common Crawl publishes the IP ranges CCBot uses: [index.commoncrawl.org/ccbot.json](https://index.commoncrawl.org/ccbot.json). A request whose user agent says CCBot from an address outside them is an impostor.

## How Punchline counts CCBot

Punchline labels a request that names CCBot with how sure it is: **verified** or **declared** when the evidence checks out, a lower tier when it can't be checked, and **impostor** when the evidence contradicts it. Each visit is counted under Common Crawl, with its purpose, so you can see whether CCBot is reading your site and which pages it reads.
