GA4 Duplicate Purchase Event Fix for Shopify | GTM Audit & Tracking Optimization

Project Overview

Transforming raw data into actionable insights through advanced tracking architecture

This Shopify store was reporting inaccurate revenue because a single purchase was triggering multiple events in GA4.

I performed a full GA4 and GTM audit, identified incorrect custom event configurations and overlapping triggers, and fixed the tracking logic.

✔️ Removed duplicate purchase events
✔️ Ensured each event fires only once
✔️ Fully validated setup using GA4 DebugView

👉 Result: Clean, reliable conversion data ready for scaling ads and making confident decisions.
