Case Study: Sunny Digital Tech achieves 18.5% lower CPA and 25% higher repurchase rate with Outbrain

Outbrain Becomes Most Profitable Open Web Platform for Sunny Digital

Sunny Digital Tech is a team of media buyers helping e-commerce brands acquire customers, grow sales, and improve profitability. Facing client demand to expand into EU markets and scale beyond social and search channels, Sunny Digital partnered with Outbrain to build email audiences, boost e-commerce sales, and drive repeat purchases across the open web.

Using Outbrain native ads, Sunny Digital targeted a regional allowlist of high‑performance publishers (e.g., Sky News, Spiegel, n‑tv), deployed Outbrain’s Conversion Bid Strategy for automated bidding, and used retargeting to re‑engage users. The campaign delivered strong outcomes: CPA was 18.5% lower vs. Google Display, page dwell time was +20%, email registrations +15%, and repurchase rate was 25% above target—helping keep CPA about 20–30% below expectations within a week.
