Attribution that survives iOS, ad blockers, and privacy changes

Browser-side pixels alone now miss a meaningful share of real conversions. iOS privacy changes, ad blockers, and cookie restrictions all chip away at what client-side tracking can see.

A server-side setup — events sent from your backend directly to Meta CAPI and GA4, deduplicated against browser-side events — recovers most of that visibility without relying on the browser at all.

It's more setup work upfront, but it's the difference between optimizing campaigns on real data versus a shrinking, biased sample of it.
