Common Crawl
Visibility Checker

Most AI training data starts at Common Crawl. This checker reads Common Crawl's own files and shows how it sees any domain: how many pages each monthly crawl captured, when an AI-crawler block first appeared in robots.txt and who wrote it, what CCBot actually archived vs the live page, whether a firewall challenges bots, sitemap coverage, and the domain's crawl priority in the web graph.

Seven checks, one input, plain-language verdicts, and copy-paste fixes for anything it finds.
