Product adoption is the process of guiding users to integrate a product into their daily workflow, ultimately leading to higher customer retention and revenue growth. Key metrics for measuring product adoption include activation rate, time to value, engagement score, customer lifetime value (LTV), customer retention rate, feature adoption rate, and product adoption rate. The stages of product adoption involve user discovery, evaluation, and adoption, with different strategies tailored to each stage. Common issues affecting product adoption include low signup-to-paid rates, low feature adoption rates, and a high number of support tickets. To improve product adoption, tactics such as creating amazing onboarding experiences, offering helpful content in-app, and continuously collecting feedback can be employed.
