The pixel is guessing.
Your server knows.
Everything that hides a conversion, blockers, iOS, consent, dropped requests, happens in the browser. Move capture to your server and the guess becomes a fact.
Ad blockers
A growing share of shoppers block the browser pixel entirely. Those conversions never reach your ad platform, but the sale still happened on your server.
iOS & ITP
Apple's tracking prevention and 7-day cookie limits drop events and break attribution windows. Server-side capture doesn't depend on those cookies.
Consent walls
Consent banners and privacy settings suppress tags, even for real buyers. Server-side respects consent while still recording the sale first-party.
Network drop-offs
Slow pages, tab closes and flaky connections mean the browser request never lands. Your server always has the order.
From half-blind to near-complete.
Server-side capture, event de-duplication and richer match data push far more conversions back to your ad platforms, so their algorithms optimise on real purchases, not a fraction of them.
- First-party, server-side events
- De-duplicated with the browser pixel
- Better match quality, lower CPA
events matched, server-side
vs ~41% with the browser pixel alone. Illustrative figures.
