notice robots.txt blocks AI search/citation crawlers

Rule geo.ai_bots_blocked · Geo · 1 occurrence(s)

  • https://daringfireball.net/ — robots.txt disallows AI search crawler(s): perplexitybot (Perplexity). These fetch pages to cite in AI answers, so blocking them removes you from that citation pool. Allowing them is required for AI citations (though not a guarantee of them); blocking training bots like GPTBot/ClaudeBot is a separate, valid choice.
