AI Crawlers / LLM Crawlers
AI crawlers are bots deployed by AI companies to crawl websites for training data and real-time knowledge retrieval. Key crawlers include GPTBot (OpenAI), Google-Extended (Google DeepMind), ClaudeBot (Anthropic), and PerplexityBot. You control access via robots.txt.
Why AI Crawlers / LLM Crawlers Matters for SEO
Allowing AI crawlers is now a strategic choice. Being crawled is a prerequisite for being cited — block GPTBot and ChatGPT can't reference you. These crawlers behave differently to Googlebot, so understanding the distinction matters for your AI visibility strategy.
How AI Crawlers / LLM Crawlers Works
Crawlers visit pages, extract content, and feed it into training datasets or real-time retrieval systems (RAG). Different crawlers serve different purposes: some collect training data, others power live knowledge retrieval. Robots.txt is the primary control mechanism for allowing or blocking specific crawlers.
Common Mistakes
- Blanket-blocking all AI crawlers in robots.txt without understanding the trade-off
- Not monitoring which AI crawlers are accessing your site via log file analysis
- Assuming blocking AI crawlers protects valuable content — it more often reduces visibility
