What Diffbot does
Diffbot's crawler, which turns web pages into structured data for its Knowledge Graph and AI products.
As an AI training crawler, it collects public pages that may be used to train AI models. The kinds of AI agent that visit websites.
Should you allow it?
A real business choice. Lean towards blocking if your content is the product (publishing, research, courses); lean towards allowing if your pages exist to sell something else. A decision guide for blocking or allowing AI crawlers.
How to allow or block Diffbot
Diffbot reads the Diffbot group in your robots.txt. To block it everywhere:
User-agent: Diffbot
Disallow: /To allow it everywhere, even if another rule blocks other bots:
User-agent: Diffbot
Allow: /Robots.txt is a request, not a lock: well-behaved crawlers follow it, impostors don't. Robots.txt for AI agents.
How to tell if it's really Diffbot
Our registry doesn't verify Diffbot against published IP ranges yet, so treat a request that uses the name as a claim, not proof: anyone can send its user agent. Check Diffbot's documentation for how to verify it.
Does Diffbot visit your site? Ghost Agent Lab reads your CDN or server logs and shows every request from Diffbot and 1,566+ other known agents: what they read, what your site sent back, and whether each request was genuine. See agent traffic, or check whether AI agents can use your site for free.
