I helped an eCommerce business improve its analytics tracking by setting up Google Analytics 4 (GA4) through Google Tag Manager (GTM) with a custom data layer. Rather than depending entirely on the standard GA4 setup, I created a structured data layer designed around the website’s actual customer journey and business requirements. I first identified the important user actions and eCommerce interactions that needed to be measured, then configured the relevant GA4 events and parameters through GTM. Once the tracking was implemented, I conducted detailed testing using GTM Preview, GA4 DebugView, and Realtime reports. Each event was checked to ensure it was firing correctly, while also looking for duplicate, missing, or incorrectly configured events and parameters. As a result, the client received a more accurate and reliable eCommerce tracking system, giving them better visibility into user behavior, conversions, and overall store performance.
