Case Study: Axel Springer SE achieves 13%+ higher open-market eCPMs with AppNexus

How AppNexus Helped Axel Springer Take Its Business to New Heights

Axel Springer SE, one of Europe’s largest digital publishing houses, needed an open and transparent advertising technology partner to modernize its ecosystem and reduce reliance on Google. The company sought a solution that could support its diverse brands across desktop, mobile, and in-app while improving how direct and programmatic demand competed.

AppNexus implemented its publisher suite, including header bidding, an ad server, and dynamic allocation, to create a holistic and transparent ad stack for Media Impact. The migration was completed in just three months, and AppNexus helped Axel Springer increase open-market eCPMs by more than 13% while giving the company full visibility and control over monetization.
