Generate a robots.txt file that correctly configures AI crawler access — GPTBot, PerplexityBot, ClaudeBot, Googlebot and more. A misconfigured robots.txt is the most common reason brands rank on Google but disappear entirely from AI answers. Fix it in 30 seconds.
Each AI engine sends its own crawler with a distinct user-agent string. Your robots.txt must explicitly name these agents — a generic Disallow: / rule blocks all of them simultaneously, and many legacy robots.txt files from 2022–2023 were written before most of these crawlers existed.
The most common AEO diagnostic finding is a brand that has correctly implemented schema markup, maintains an active content strategy, and has strong E-E-A-T signals — but still gets zero citations from ChatGPT or Perplexity. The culprit, in almost every case, is a robots.txt file that blocks the relevant AI crawler.
This happens because most robots.txt files were written for the Google-and-Bing era of 2015–2022. The bot names GPTBot, PerplexityBot, and ClaudeBot didn't exist then. Many sites use wildcard rules or blocking patterns that silently catch all new crawlers — including every AI bot launched in the last three years.
Fixing robots.txt is the fastest AEO win available. A single file change can immediately restore AI crawler access, and citation improvements from newly accessible content can appear on Perplexity within days. Use the llms.txt Validator to confirm your configuration after updating.
User-agent: GPTBot Allow: / User-agent: PerplexityBot Allow: / User-agent: ClaudeBot Allow: / User-agent: Grok-Bot Allow: / User-agent: * Disallow: /admin/ Disallow: /api/private/
Allow GPTBot, PerplexityBot, ClaudeBot and other AI agents. This opens the door for crawlers.
