meta-externalads
Meta’s ads-related fetcher. Allow it on destinations you run as Facebook/Instagram ads or the preview will not match the live page.

- Usually honors robots.txt
Usually means: Link-preview, ads, and product fetchers. Allow them if you want unfurls and landing-page fetches to work; they are not the citation path.
User-agent
robots.txt and most WAF rules match the token, not the full Mozilla string. Operators often wrap meta-externalads in extra product or version text.

What meta-externalads does
meta-externalads fetches pages for advertising and business-product use cases. It is not the AI-search indexer.
How to get discovered
Allow this UA on ad landing pages. Keep the first paint honest — ads crawlers that see a different page than users create policy and quality problems.
Why meta-externalads might skip you
Bot blocks on paid domains, or geo fences that Meta’s fetchers fail.
robots.txt rule
Allow this token on public pages you want retrieved or cited. A CDN “Block AI bots” toggle can still 403 it after robots.txt says Allow.
# Keep meta-externalads eligible to fetch this site
User-agent: meta-externalads
Allow: /Meta has not published a machine-readable range file for this token. Do not treat the user-agent alone as proof of identity.
JavaScript: render behavior is not documented.
Other Meta bots
Training, search, and user-fetch tokens from the same operator are not interchangeable. Allow the discovery path even when you opt out of training.
meta-externalads FAQ
What is meta-externalads?
meta-externalads fetches pages for advertising and business-product use cases. It is not the AI-search indexer.
Should I allow meta-externalads in robots.txt?
Yes if you want Meta to be able to fetch and cite this site. Blocking meta-externalads is how pages stay invisible to that product even when Googlebot still crawls them.
How do I know a request is really meta-externalads?
Meta has not published a range file for this token. Treat the user-agent as a claimed identity, and do not build a hard IP allowlist from blog posts or screenshots.
Letting meta-externalads in is the start. Getting cited is the job.
Rankealo checks whether AI crawlers can reach you, then publishes pages built to be retrieved and quoted in ChatGPT, Claude, Perplexity, and Gemini.
