Cloaking for Facebook Ads
Meta reviews a landing page with its own crawler at ad approval time, and — unlike a one-time check — can send a second, residential-looking re-crawl afterward to verify a live page still matches what was approved. Cloaking X's job on a Meta stream is to recognize both passes and route them away from your money page.
How Meta's Review Crawler Inspects a Landing Page
Meta's automated review identifies itself with the facebookexternalhit user-agent and originates from Meta's own autonomous system (AS32934) when it fetches the destination behind an ad. That combination of UA and network origin is distinct from the Facebook or Instagram app a real viewer arrives from.
Meta can also follow up with a second review from residential-looking IP ranges rather than its own datacenter network — a re-crawl that doesn't carry the same obvious facebookexternalhit/AS32934 signature as the first pass, which is why detection needs to look at more than one signal.
How Cloaking X Filters Meta Review Traffic
Cloaking X attributes facebookexternalhit and AS32934-origin requests in real time, at the edge, before the request reaches your money page. Delayed re-crawl detection separately flags a device fingerprint returning to the same stream after an unusual delay — catching the residential-looking second pass a UA/ASN check alone would miss.
The same stream captures fbclid (Meta's click identifier) automatically, so Meta Conversions API keeps attributing the clicks that do reach your offer.
facebookexternalhit & AS32934 Attribution

Delayed Re-Crawl Detection
Flags a device fingerprint returning to the same stream after an unusual delay, including residential-looking re-crawls that don't carry Meta's own network signature.

Setting Up Meta Ads in 3 Steps
- 1
Create a stream
Set your fallback page (or use the built-in generator) and your money page(s) for this campaign.

Most Meta Ads streams run proxy or 302 redirect delivery — pick the mode that matches your setup.
- 3
Point your Meta Ads destination URL at the stream
Use the stream link (or your own domain, if you're on a plan with custom domains) as the ad's website URL.
Filter Meta's Reviewers, Not Your Real Traffic
Start on the Free plan — one stream, 300 clicks/day, no time limit — and see how Meta review traffic gets routed differently from real visitors.
