AI crawler

In short

An AI crawler gathers pages on its own schedule, so blocking one changes what an AI system knows about you later, not a customer's request today. Cloudflare reported that 52 percent of crawler requests it saw in June 2026 were for AI training by stated purpose.

Definition

A bot that collects pages in bulk on its own schedule, to train a model or build an AI search index. Blocking it changes what an AI system knows about you later, not a customer's request now.

A dated example

Where it matters

Blocking one changes what an AI system knows about you later, not a customer's request today.

  • Training crawlerA crawler that takes pages to train or fine-tune an AI model.
  • AI search crawlerA crawler that indexes pages so an AI search product can answer questions and cite them later.
  • Mixed-use crawlerOne crawler that does both search indexing and AI training, so refusing one used to mean refusing the other.
