Global Apparel Retailer: Recovering 28% of Lost Conversion Data
How we bridged tracking gaps caused by iOS updates and ad blockers, leading to a 2x increase in measurable ROAS.
The Client
Global Apparel Retailer
A global e-commerce fashion brand with a high volume of mobile traffic.
The Service
First-Party Data Infrastructure
Server-side GTM and CAPI implementation.
Key Result
28% Recovery
Reclaimed lost conversion data and doubled measurable ROAS.
The Challenge
The retailer was suffering from significant signal loss due to iOS 14.5+ updates and the increasing prevalence of ad blockers. Their client-side pixels were failing to capture nearly a third of all conversions, leading to deflated ROAS reporting and poor ad optimization.
The Solution
Server-Side Tracking
We migrated their core tracking from client-side pixels to a robust Server-Side Google Tag Manager (sGTM) setup.
Conversions API (CAPI) Integration
Implemented Meta CAPI and Google Ads Enhanced Conversions to directly send first-party data from the server to ad platforms, bypassing browser restrictions.
The Results
28% More Conversions
Recovered previously untrackable sales.
2x ROAS Increase
Ad algorithms optimized effectively with restored data signals.
