Case Study: 33Across achieves 120% monthly revenue growth with AppNexus Header Bidding

Putting the Right Pieces Together to Help Publishers Monetize

33Across, a publisher monetization platform that helps companies like The New York Daily News and CBSi improve ad revenue, wanted a better header bidding strategy to support multi-size creative auctions, reduce latency, and increase fill rate and revenue for its publishing partners. The company tested AppNexus’ header bidding solution to find a scalable platform that could meet those goals while improving user experience.

AppNexus recommended a single, multi-size auction approach that 33Across implemented with its internal engineering team. The result was a major performance lift: total available impressions grew 31%, fill rate increased 101% in one month, and monthly revenue rose 120%, while latency dropped significantly.
