AI crawling refers to the process by which AI platforms send automated bots to discover, access, and index web content for use in their AI-generated responses. Different AI platforms have different crawling behaviors: some crawl the web broadly like traditional search engines, while others rely on real-time retrieval for specific queries.
Key AI crawlers include GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, and various Google crawlers. Each has different access patterns, frequency, and content preferences.
Managing AI crawler access is an important part of AEO strategy: you want to ensure valuable content is accessible to AI crawlers while potentially restricting sensitive or duplicate content.
If AI crawlers can't access your content, AI platforms can't cite you. Many websites inadvertently block AI crawlers through robots.txt rules or technical barriers, making them invisible to AI search.
Conversely, understanding how AI crawlers work helps you optimize your site structure and content presentation for maximum AI discoverability.

For most businesses, allowing AI crawlers is beneficial as it enables AI platforms to cite your content. However, some publishers choose to restrict access to protect proprietary content.
