Case Study: Allianz achieves an 83% reduction in customer acquisition cost with StackAdapt

Driving Success With a Cost-Cutting Auto Insurance Campaign

Allianz partnered with StackAdapt to optimize lead acquisition for its car insurance products in the French market. Allianz faced challenges tracking and attributing conversions across multiple touchpoints and engaged the StackAdapt platform for a programmatic, lead-generation test to improve attribution and efficiency.

StackAdapt implemented domain inclusion/exclusion, advanced audience segmentation, tailored creatives, and private marketplace (PMP) deals with top sites to target high-quality traffic. Over a three-month test the campaign drove 21,050 clicks and 387 leads at a CPM of €1.32, delivering an 83% reduction in customer acquisition cost (CAC), demonstrating clear programmatic performance gains.
