Case Study: NARUKO achieves up to 9% lower CPA and 433% higher cross‑screen CTR with Appier's CrossX AI

NARUKO - Customer Case Study

NARUKO, a Taiwanese beauty brand selling globally, wanted to reach consumers across all screens to boost transactions while keeping acquisition costs low. The challenge was identifying and engaging cross-screen shoppers effectively to increase conversions without raising CPA.

Using Appier’s CrossX AI, NARUKO targeted loyal members, expanded prospects with CrossX Lookalike, and deployed CrossX Remarketing to tailor product recommendations and creatives to each user’s cross-screen journey. The campaign cut monthly CPA by up to 9% versus target, produced a cross-screen CTR 433% higher than multi-screen CTR, and achieved up to 91% higher CTR among users with both PCs and phones—revealing PCs played a larger role, with the top conversion path being PC → phone browse → PC conversion.
