Case Study: Chow Sang Sang cuts CPA by 52% and boosts CVR by 49% with Appier's CrossX and AiDeal

Appier’s CrossX and AiDeal solutions help decrease CPA by 52% and increase CVR by 49%

Chow Sang Sang, a premier Greater China jeweler with an e-commerce site since 2014, faced two core challenges: matching its 2,000+ product SKUs to the right online shoppers and converting hesitant luxury buyers who often abandoned carts. Traditional rule-based targeting was labor-intensive and ineffective, leaving revenue opportunities on the table.

Appier’s CrossX and AiDeal provided AI-driven keyword/interest segmentation and real-time detection of hesitant behavior (using 400+ on-site signals) to deliver personalized creatives and timed checkout offers. This targeted, automated approach identified four high‑potential segments, reduced CPA by 52%, and increased on-site conversion rate by 49%.
