Does CCBot respect robots.txt?

Common Crawl documents CCBot and robots.txt opt-out. A User-agent: CCBot Disallow: / group is the standard way publishers exclude themselves from Common Crawl collection.

Is CCBot run by OpenAI?

No. CCBot is operated by Common Crawl, a nonprofit. Many organizations may use Common Crawl data later, but the crawler itself is not GPTBot.

Does blocking CCBot affect Google rankings?

No. CCBot is unrelated to Googlebot. Blocking it only affects Common Crawl’s dataset collection from your site.

Why is CCBot important if I already block GPTBot?

Open datasets can still feed research and some training pipelines downstream. CCBot is an independent control surface from proprietary AI company crawlers.

What happens if I allow CCBot?

Public pages may appear in future Common Crawl snapshots used by researchers and companies. That can increase reuse of your public content in ML contexts.

Where is official CCBot information?

See Common Crawl’s CCBot documentation (linked on this page) for robots.txt guidance and crawler identity details.

What is CCBot?

CCBot is the crawler operated by Common Crawl, a nonprofit that publishes large open web datasets. Those datasets are widely used by researchers and organizations training or evaluating language models. Blocking CCBot via robots.txt is a common way publishers opt out of Common Crawl’s collection; allowing it means your public pages may appear in future dataset snapshots. CCBot is not a product of OpenAI, Anthropic, or Google, but its data can flow into many downstream AI projects—making it strategically important even when the brand name is less famous than GPTBot.

How to block CCBot

Add this group to robots.txt to disallow CCBot. Path rules can be narrowed if you only need to protect parts of the site.

User-agent: CCBot
Disallow: /

How to allow CCBot

For most public marketing and documentation sites, allowing well-behaved AI agents is the default recommended stance for AI visibility—while remaining a factual robots.txt Allow rule you can reverse later.

User-agent: CCBot
Allow: /

Should you block CCBot?

CCBot is a dataset crawler: the immediate product is an open corpus, not a single chat UI. Publishers with strict training opt-out policies often block CCBot; those comfortable with open research reuse may allow it. Blocking CCBot does not block proprietary crawlers from other companies—you must configure each agent. Review Common Crawl’s current CCBot documentation for robots.txt details and contact paths if you see unexpected crawl behavior.
