Seznam.cz case study: from in-house CMP to a stronger publisher network


Seznam.cz is a major Czech technology company, European publisher, and identity provider, operating a search engine, news portal, email service, price comparison portal, mapy.com, and a network of premium publisher properties. For years, they ran their own IAB-certified CMP, supporting publishers across their network.

But as TCF requirements grew more complex and the platform’s role expanded with features like a pay-or-OK model and user login integrations, maintaining the in-house CMP became harder to justify. Seznam.cz decided to deprecate their own solution and move every publisher to a dedicated platform built for performance and scale.

By switching to consentmanager by iubenda, Seznam.cz gave their publisher network full control over consent performance, with customization, A/B testing, and self-serve reporting they never had before.

The results at a glance:

  • Almost 100 publishers moved to consentmanager without disruption
  • 3 new capabilities unlocked: A/B testing, customizable banner design, and live statistics
  • Significant uplift in consent rates after switching
  • Each publisher now manages consent independently through their own consentmanager account

“When we decided to deprecate our CMP for external publisher partners, our priority was making the transition as easy as possible. Switching from a free solution we provided since 2018 was a very sensitive topic. consentmanager by iubenda gave them everything they needed to get started for a fair price, and more than they had before.” – Jakub Novotný, Identity Solutions Manager, Seznam.cz
