Rebuilt the checkout flow and server-side measurement stack to eliminate conversion friction, resolve tracking discrepancies, and create a reliable 1:1 ads-to-revenue match.
The business faced two connected problems: the checkout experience was leaking customers at the final payment step, while client-side pixel tracking suffered significant event loss from ad-blockers and browser privacy restrictions. Platform numbers and ad-manager figures disagreed daily, making it difficult to allocate ad spend with confidence.
Fragile client-side tracking, multi-step checkout friction, and daily discrepancies between reported ad revenue and actual merchant payouts.
Clean, responsive checkout architecture backed by robust server-to-server tracking APIs directly matching live bank receipts.
Engineered across the complete technical workflow with thorough QA and zero downtime.
Rebuilt the complete checkout flow around native Stripe and PayPal integrations, eliminating redundant form fields and optimizing mobile touch interactions.
Implemented dedicated server-side Google Tag Manager connected directly to Meta Conversion API (CAPI) and Google Conversion API with cryptographic event deduplication.
Ran iterative, hypothesis-driven split tests on button hierarchy, trust badges, payment order, and shipping selector usability to maximize completion rate.
To achieve true 1:1 attribution match, conversion events are triggered securely from the server after payment confirmation from Stripe/PayPal webhooks, bypassing client-side browser limitations completely.
"They rebuilt our checkout and wired proper server-side tracking in six weeks. Conversion is up 19% and for the first time our ad numbers actually match our bank account. Worth every euro."
