Google Ad Manager Delivers 34% Revenue Growth for Zoznam and WeProgrammatic

Google Ad Manager

Zoznam.sk is one of Slovakia's oldest and most prominent internet portals, functioning as a comprehensive digital hub that offers a search engine, news coverage, and a wide array of specialized lifestyle and entertainment services.

The challenge

Google Ad Manager

Zoznam relied on a third-party vendor for anchor ads, causing limited control and suboptimal eCPMs. The publisher needed to migrate this format in-house to reduce fees, regain control, and boost overall inventory quality and revenue.

The approach

Google Ad Manager enabled WeProgrammatic, the agency managing programmatic for Zoznam, to seamlessly replace an external anchor format with Open Auction demand. A custom Google Ad Manager template integrated the ad unit directly, delivering complete control over demand, price management, and creative settings to optimize yield.

The results

  • +63%
    eCPM Y/Y growth for the anchor format, Q1 ‘26
  • +34%
    Y/Y revenue growth for the anchor format, Q1 ‘26
  • +13%
    Viewability growth of their account, Q1 ‘26

We were very excited to migrate this format "in-house" as it gives the publisher full control over this highly visible inventory. Thank to Google, the process was very straightforward and smooth.
