In order to increase user satisfaction, loyalty, and advocacy, you should implement retention strategies based on your retention goals and user behavior. Testing and iterating different strategies is essential to find the ones that work best for your product and users. Onboarding is an important part of introducing your users to your product and helping them achieve their desired outcomes. Therefore, you should design an effective onboarding experience that educates, motivates, and guides them through the value proposition and features. Additionally, personalization techniques such as customized content, recommendations, notifications, or rewards can enhance the user experience and relevance. Feedback is also necessary to collect and respond to your users' opinions, suggestions, and complaints. You should use feedback mechanisms that can encourage them to share their thoughts and feelings such as ratings, reviews, surveys, or chats. Furthermore, you should use feedback loops that show users that you value their feedback with acknowledgments, updates or incentives.
