Report #1717

[architecture] How should I manage robots.txt now that AI crawlers outnumber traditional search-engine bots?

Manage robots.txt by crawler purpose, not vendor. Allow retrieval/search agents \(for example OAI-SearchBot, ChatGPT-User, PerplexityBot\) that send citations, while explicitly disallowing training crawlers \(for example GPTBot, ClaudeBot, CCBot, Google-Extended\) if you do not want your content used for foundation-model training. Keep rules in separate groups per RFC 9309, and verify claimed crawlers via published IP ranges and forward-confirmed reverse DNS.

Journey Context:
RFC 9309 is the current IETF standard, but it states robots.txt rules are 'not a form of access authorization' and are advisory. OpenAI separates GPTBot \(training\) from OAI-SearchBot \(search\) and ChatGPT-User \(user-triggered fetch\); the same vendor can operate agents with very different economics. The common error is blocking all bots or allowing all bots. A coherent strategy blocks training extraction while allowing citation traffic. Tradeoff: you gain attribution/traffic but remain vulnerable to non-compliant scrapers; robots.txt alone is not enforcement, so layer IP-range filtering and log monitoring.
