Customer retention analytics is a strategic process that involves tracking, analyzing, and predicting customer behavior to understand retention patterns and reduce churn. By focusing on key metrics such as churn rate, lifetime value (LTV), and customer acquisition cost (CAC), businesses can identify valuable customer segments and enhance loyalty. Techniques like cohort analysis, survival curves, and RFM segmentation provide deeper insights into customer behavior, enabling targeted retention strategies. Tools like Hex facilitate this process with interactive dashboards that visualize trends, predict churn, and connect retention metrics to business outcomes. Effective retention strategies, supported by analytics, not only improve customer lifetime value but also make acquisition costs more efficient, driving sustainable growth.
