Case Study: How REWE cuts media waste with first-party data
Key results
The challenge
REWE Group aimed to reduce media-spend waste and expand acquisition efficiently, but low match rates blocked effective audience suppression, letting excluded audiences still receive impressions. Existing modelling lacked consistency and decentralised teams faced operational bottlenecks.
The solution
REWE adopted Zeotap CDP to unify offline and online first-party signals, improve match rates for suppression, and enable more than 70 users across its teams on the platform.
“By using Zeotap, we significantly increase conversion rates and efficiency, translating precise targeting directly into measurable business impact.”

The results, in context
Selected campaigns achieved media budget savings of over 4% through improved audience suppression, and more than 70 users were enabled on the platform.
