Success Story: How S2S Integration Drove +189% More Tracked Conversions

Facing increasing cookie restrictions and the limitations of pixel-based tracking, GRAN partnered with Admitad to migrate to Server-to-Server (S2S) integration via GTM Server-Side. The result: +189% more tracked conversions, +150% in CR, and +149% in EPC — proving how essential S2S is for accurate and scalable performance tracking.

The Challenge

GRAN’s conversion tracking relied on browser-based methods highly vulnerable to ad blockers, cookie loss, redirect issues, and cross-device behavior. This caused real conversions to go untracked, reduced attribution for publishers, and led to customer complaints when rewards or cashback were not validated correctly.

The Solution

By adopting S2S integration, GRAN began sending conversion data directly from its server to Admitad’s — eliminating dependence on browsers and ensuring reliable attribution.
The IT and Marketing teams worked together on parameter mapping, testing, and validation to guarantee a precise data flow.

Leading improvements included:

• Direct and secure server-to-server conversion tracking
• Strong resilience against cookie restrictions
• Accurate attribution across channels and devices

The Results (45 days before vs. 45 days after migration)

• +126% Clicks
• +189% Actions (tracked conversions)
• +150% CR
• +149% EPC

These metrics demonstrate a dramatic leap in tracking accuracy and overall campaign performance.
