AI Crawler
AI Crawler — A web crawler operated by an AI company to index content for their models. Key AI crawlers include GPTBot (OpenAI), Anthropic-AI (Claude), Google-Extended (Gemini and Google AI), PerplexityBot (Sonar), and xAI crawler (Grok). Websites can allow or block these crawlers via robots.txt directives.
AI crawlers are the web bots that AI companies use to index content for their models. Unlike Googlebot (which indexes for search rankings), AI crawlers index content for training data and real-time retrieval. The major AI crawlers are GPTBot (OpenAI), Anthropic-AI (Claude), Google-Extended (Gemini and Google AI), PerplexityBot (Perplexity), xAI crawler (Grok), and Bytespider (ByteDance).
For AEO, it is critical to ensure your robots.txt allows AI crawlers access to your marketing pages. Blocking GPTBot, for example, means OpenAI cannot access your latest content and may rely on outdated training data. CiteRank's optimization recommendations include robots.txt auditing to ensure AI crawlers can index your most important pages.
