What is meta-externalads?
meta-externalads is a web crawler operated by Meta. It reads pages for advertising-related purposes, as documented alongside Meta's other external agents. The crawler identifies itself with the user-agent token meta-externalads and respects robots.txt directives. Its activity is separate from Meta's AI training or search indexing bots, focusing instead on how pages are used within Meta's advertising systems. Site owners can control its access through standard robots.txt rules.
What it's for
If you run ads on Meta platforms or use Meta advertising tools, this crawler may read your pages to support ad delivery, measurement, or relevance. Blocking it could limit Meta's ability to use your page content for those advertising features, potentially affecting ad performance or targeting capabilities that rely on page data.
How to handle meta-externalads
To prevent meta-externalads from accessing your site, add a Disallow rule for its user-agent token in your robots.txt file. The crawler honors robots.txt, so this is the standard method to control its visits. There is no separate control token required.
robots.txt rule
User-agent: meta-externalads Disallow: /
Blocking cost
