Project Details:
📘 Project Description:
The client, a growing eCommerce business, struggled with incomplete or delayed and experienced underreported conversions and poor ROAS due to blocked browser events in Google Ads. Without proper tagging and funnel visibility, they couldn’t optimize campaigns or track real ROI.Using Google Tag Manager Web + Server containers and hosting the server on Stape.io, we set up dual tracking:
✅ Browser-side: Standard Ads conversion tags + Enhanced Conversions
✅ Server-side: Data pushed from Web GTM to Server GTM, then to Google Ads via Enhanced Conversions API
The tracking now bypasses client/browser blockers and ensures every conversion is counted accurately—essential for Smart Bidding and ROAS optimization.
The Challenges —–
Prior to Pixel implementation, the client faced :
🚫 Lost conversions from iOS/Safari/ad blockers
🚫 Weak data signals to Google Ads’ Smart Bidding
🚫 ROAS underreporting due to browser-only pixel limits
🚫 No Enhanced Conversions or hashed identifiers
🚫 No deduplication → inflated conversion data
🚫 Inability to scale ads due to poor data visibility
These gaps lead to underreported results, ineffective optimization, and wasted ad spend.
✅ Our Solution
After Implementation – All Issues Solved
We deployed a dual-layered solution (browser + server), fully tested using GTM Preview, Tag Assistant, and Google Ads Debug tools.This allows Google Ads to read clean conversion signals across all pages and devices—boosting both accuracy and optimization potential.
📊 Events Tracked (Browser + Server-Side Setup)
| Event Name | Browser Pixel | Server (CAPI) |
|---|---|---|
| add_to_cart | ✔️ | ✔️ |
| begin_checkout | ✔️ | ✔️ |
| purchase | ✔️ | ✔️ |
| form_submit | ✔️ | ✔️ |
After giving a preview from the GTM Browser and Server-Side, we see that all tags have fired successfully.
Custom Domain Setup with Stape.io to enhance tracking accuracy and ensure compliance with privacy regulations.
