What key performance indicator (KPI) would be MOST helpful for evaluating the success of Samsung Rewards integration?

The Key Performance Indicator (KPI) that would be MOST helpful for evaluating the success of Samsung Rewards integration is the increase in the ratio of lifetime value (LTV) to customer acquisition cost (CAC) among users actively engaging with the Samsung Rewards program within the app. This metric combines the long-term revenue generated by users who participate in Samsung Rewards with the cost of acquiring those users, providing a comprehensive view of the program's profitability and impact on user loyalty. For example, if users who actively use Samsung Rewards have a significantly higher LTV/CAC ratio compared to non-rewards users, it indicates that the program is effectively driving user engagement, retention, and revenue generation. Tracking this KPI requires measuring both the revenue generated by rewards users and the cost of acquiring and retaining those users, including any incentives or promotions offered through the program. A higher LTV/CAC ratio signifies a more successful and sustainable Samsung Rewards integration.
