Case Study: Nexon Exceeds CPX and ROAS Targets with Remerge Retargeting

Nexon beats CPX targets by 59% and lifts ROAS 138% with Remerge

Nexon, a global leader in online games, sought to improve the return on ad spend (ROAS) and lower the cost per reattribution (CPX) for its mobile game MapleStory M in South Korea, particularly in the challenging iOS environment post-ATT. They partnered with the vendor Remerge to run an in-app retargeting campaign focused on re-engaging users across both iOS and Android platforms.

Remerge implemented a solution that segmented users based on inactivity and purchase history, utilized top-performing ad formats, and leveraged advanced machine-learning for bid optimization. As a result, Nexon significantly exceeded its performance goals. On Android, CPX was 52% cheaper and ROAS was 138% higher than targets. On iOS, CPX was 59% cheaper and ROAS was 51% higher. Based on this success, Nexon scaled its monthly ad spend with Remerge for MapleStory M by 800% within the first year.
