Executive Summary
Pixum implemented the JENTIS server-side tag manager to improve marketing data quality and build a GDPR-compliant, future-proof tracking setup. The result: up to 44% more orders in Safari browsers, which are known for strict tracking prevention. These results highlight the effectiveness of JENTIS in overcoming browser-related data loss and boosting campaign performance through more reliable analytics and attribution.
Challenge
Starting in 2020, Pixum experienced a sharp decline in data quality caused by browser-based tracking prevention (e.g. Safari’s ITP) and widespread ad blocker usage. This led to data inconsistencies of more than 20% across web analytics, ad platforms, and internal BI systems — making it harder to allocate budgets efficiently and measure performance accurately.
Solution
Pixum defined two core objectives for the tracking overhaul:
- Improve data quality across all marketing tools
- Ensure GDPR compliance with a robust, future-ready setup
To reach these goals, Pixum implemented the JENTIS server-side tag manager. In a direct comparison with client-side tracking, the new setup led to:
- +11% more tracked conversions
- +55% corrected customer journeys
- A +31% increase in campaign budgets and +176% new customer revenue in the first campaign
One year later, these changes were rolled out across all channels and markets — with significant uplift in Safari and other browsers.
Results & Impact

Pixum saw a substantial increase in orders, especially in browsers with strict privacy restrictions:
- +4% in Chrome
- +27% in Firefox
- +35% in Safari (in-app)
- +44% in Safari (browser)
This proves that high-quality server-side data from JENTIS not only improves attribution accuracy but also boosts campaign ROI — even in tracking-restrictive environments.
