FacebookBot
Meta uses this crawler to collect content for AI model training. Crawls to train Meta AI models.
What is FacebookBot?
Crawls to train Meta AI models. Training-data crawlers collect publicly available pages to build future AI models. Allowing one means your content can shape how models write and reason about your topics, and your site may be quoted from model memory. Blocking one keeps future training runs away, though anything already collected typically stays collected.
If you want AI engines to know your brand and quote your pages from memory, this is the crawler that gets you there.
Does FacebookBot respect robots.txt?
Yes. FacebookBot honors robots.txt directives, including wildcard rules and Allow lines. A Disallow rule for this crawler is respected — but remember robots.txt is a voluntary protocol across the whole industry, not a wall.
How to block FacebookBot
Add this group to your robots.txt to deny FacebookBot across your whole site:
User-agent: FacebookBot Disallow: /
If you monetize content behind a paywall or care about control, allowing broad training crawlers means giving that material away with no attribution loop.
How to allow FacebookBot
FacebookBot is allowed by default on every site. It only gets blocked if a matching rule exists — most often a global User-agent: * group with Disallow: /. To exempt it while blocking other bots, put an empty Disallow group for it before the global block:
User-agent: FacebookBot Disallow: User-agent: * Disallow: /
