Frequently Asked Questions

What Traffic Patterns Should I Expect From CloudFlare-Prefetch?

CloudFlare-Prefetch usually performs comprehensive, link-following crawls rather than spot checks. Visit frequency may rise while a customer actively monitors your site or a related market.

Does CloudFlare-Prefetch Follow Robots.txt Rules?

CloudFlare-Prefetch is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether CloudFlare-Prefetch respects it.

Is CloudFlare-Prefetch Used for AI Model Training?

Not ordinarily. CloudFlare-Prefetch is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.

Does Blocking CloudFlare-Prefetch Affect AI Search or Citations?

Not directly. CloudFlare-Prefetch's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.

Does CloudFlare-Prefetch Access Private Content?

No. CloudFlare-Prefetch can reach only public pages, and authentication prevents it from accessing private content.

How Can I Verify a Request From CloudFlare-Prefetch?

Agent Analytics tracks CloudFlare-Prefetch visits in real time. You can also check your server logs for requests whose user-agent string contains "CloudFlare-Prefetch". Look for comprehensive site crawls that follow internal links. Because CloudFlare-Prefetch does not publish a verification method, any client can claim its identity and a log match is only a clue.
