01 The problem
02 What we changed
03 What it did
Browser tracking loses conversions to ad blockers, privacy settings and short cookie windows. The sales still happen; the ad platforms just never hear about them.
Counting what you already won
We send conversions from your server through each platform’s conversions API, matched to orders in Shopify and events in GA4. The models suddenly see customers they were already winning, and bid for more like them.
