Sites that block CCBot
3,349 of the 30,374 domains we have measured, 11%, disallow ccbot at the site root in robots.txt. CCBot archives content.
Every domain here has withheld its content from Common Crawl Foundation's training crawl. That is a separate decision from appearing in the operator's answers, which is governed by a different token.
3,349 of 30,374 measured domains (11%) disallow ccbot at the site root in robots.txt. Every domain named on this page was fetched directly and its robots.txt parsed against RFC 9309; none of it is inferred from a third-party index.
Measured 2026-08-26 by direct request to every domain in the corpus. Method: how this is measured. Reuse under CC BY 4.0 with attribution.

The list 3,349 domains
Rank is the domain's position in the popularity list used to seed the corpus; a dash means it was scanned on request rather than seeded. Score is the site's overall AI access score, which blocking depresses but does not by itself determine.
