Cloudflare estimated June 2025 crawl-to-referral ratios of about 14:1 for Google, 1,700:1 for OpenAI and 73,000:1 for Anthropic on its network.
What this does not establish
Ratios do not measure licensing value, citation frequency or user welfare.
Counterevidence & uncertainty
Native-app referrals may omit Referer headers; crawler identities and client mix differ.
What would change the reading
Cloudflare updates methodology or time series.
