Executive Summary
To drive sustainable growth through performance marketing, aqua blue implemented server-side tracking with JENTIS. The improved data quality enabled the company to accurately capture conversion data and feed it into Google Ads. The result: a 36% lower Cost per Acquisition (CPA) in PMAX campaigns and a significantly higher ROI across all campaign types.
Challenge
aqua blue relied heavily on Google Ads PMAX and search campaigns to acquire new customers. However, their previous client-side tracking setup (using Google Tag Manager and Google Analytics) faced serious limitations:
- Ad blockers and browser privacy features (e.g. Apple’s ITP) caused data loss
- Incomplete conversion data reduced the effectiveness of algorithmic bidding and targeting
- Duplicate user counts and gaps in customer journeys distorted analytics and decision-making
To overcome this, aqua blue needed a data-resilient, precise, and future-proof tracking solution.
