Track this bot on your siteWhat is FacebookBot?
FacebookBot downloads web content to train Meta's AI speech recognition and language models. Separate from facebookexternalhit which handles link previews.
What FacebookBot means for your site
FacebookBot downloads your content to include in datasets used to train AI models, operated by Meta. Your text becomes part of the AI's general knowledge, but without direct attribution or links. This is a key distinction: training crawlers take your content, AI assistants cite it. You can control training access via robots.txt without affecting citations.
What should you do?
- Decide whether you want Meta to train on your content
- Block via robots.txt if unwanted: User-agent: FacebookBot / Disallow: /
- Monitor crawl patterns for unexpected spikes
- Review BotSights data to see which pages are targeted

BotSights tracks every FacebookBot visit in real time, including which pages it crawls, how often, and from where.
How to identify FacebookBot
FacebookBot uses the user-agent "FacebookBot" and respects robots.txt. It crawls broadly and systematically, often downloading full page content.
FacebookBotfacebookbotHow to block FacebookBot
Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known FacebookBot user-agent pattern so the rules apply regardless of which one the bot announces.
Edit robots.txt with care
A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just FacebookBot, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to FacebookBot's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.
Option 1: Block all access
Tells FacebookBot not to crawl any URL on your site. Use this when you want the bot completely off your content.
User-agent: FacebookBot
User-agent: facebookbot
Disallow: /Option 2: Block specific paths only
Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.
User-agent: FacebookBot
User-agent: facebookbot
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/Option 3: Slow down with a crawl delay
Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when FacebookBot is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

Crawl-delay: 10Frequently Asked Questions
What is the User-Agent for FacebookBot?
FacebookBot identifies itself with the User-Agent string "FacebookBot" (alternate forms: facebookbot). Use this exact string in robots.txt rules to control access.
Can I stop FacebookBot from using my content for AI training?
Yes. Add this to your robots.txt: User-agent: FacebookBot / Disallow: /. Meta commits to respecting robots.txt for training data.
Will blocking FacebookBot affect my AI citations?
No. FacebookBot is a training crawler, separate from real-time AI assistants. For example, blocking FacebookBot does not block Meta's user-prompt assistants from citing your content live.
What's the difference between FacebookBot and an AI assistant bot?
FacebookBot crawls broadly to build training datasets — your content becomes part of the model's general knowledge but without direct attribution or links. AI assistant bots (like ChatGPT-User, Claude-User) fetch specific pages in response to user prompts and cite sources back. They use separate User-Agents and can be controlled independently.
How do I verify that a request is really from FacebookBot?
User-Agent alone is not enough — anyone can claim to be FacebookBot. Meta may publish IP ranges or reverse-DNS verification in their crawler docs. BotSights flags spoofed traffic automatically.
Is my content being used without permission?
Training crawlers collect publicly accessible content. The legal landscape around this is rapidly evolving (lawsuits in the US, EU AI Act, etc.). Robots.txt remains the most practical opt-out mechanism today, plus emerging standards like ai.txt.
How often does FacebookBot crawl?
Training crawlers usually visit periodically — weekly or monthly waves rather than daily. If you see sudden spikes, monitor whether the bot is honoring Crawl-delay directives in your robots.txt.
