Case Study: Chengdu Droidhang achieves 2X return on ad spend with Facebook

Chengdu Droidhang - Customer Case Study

Chengdu Droidhang, a mobile game developer in Chengdu best known for the popular gacha RPG Idle Heroes, needed to acquire high-value players worldwide who would make in-app purchases — without running separate campaigns for every country. Their challenge was scaling efficient user acquisition across many markets while prioritizing users likely to spend.

They used Facebook App Event optimisation and mobile app install ads, first targeting a core set of key countries (US, Canada, France, Germany, Korea, Japan, UK, Thailand, Vietnam) and then running a worldwide campaign excluding those markets, optimizing for the “purchase” event. This approach doubled return on ad spend, cut cost per install by 20% and improved 7-day retention by 12%.
