Cloudflare's bot-fight mode and many default WAF configurations are built to stop scraping and credential-stuffing bots, but they frequently classify AI crawlers — GPTBot, ClaudeBot, Google-Extended, PerplexityBot — under the same blanket rule, returning a 403 before the crawler ever reads a page. The business owner never sees an error; the site looks fine to a human visitor while being functionally invisible to every AI assistant that would otherwise cite it. This is common on sites that enabled aggressive bot protection for legitimate security reasons and never revisited the rule once AI crawlers became a distinct traffic category worth allowing. Diagnosing it requires checking server logs or crawler-specific testing tools, not just viewing the site in a browser. AI HALO's audit tests exactly this — whether each major AI crawler can actually reach and parse the site — and corrects the blocking rules as part of the unblocking work before any structured-data or citation effort would otherwise go to waste.

Review server or Cloudflare firewall logs for requests from GPTBot, ClaudeBot, Google-Extended, and PerplexityBot user agents and check their response codes; a 403 or challenge response means the crawler is being blocked before it can read your content.
No — you can allow specific, verified AI crawler user agents and IP ranges while keeping bot-fight protections active against everything else; it's a targeted allowlist, not a general loosening of security.
robots.txt only requests that a crawler skip a path — it doesn't stop a firewall or bot-fight rule from blocking the request outright. Both layers need to explicitly permit the crawler for it to succeed.
