Tracking customer retention is essential; it helps you understand how many users continue to engage with your product over time, which is a key indicator of success.

Be cautious of measuring retention over too long a time period, as this can artificially inflate your retention metrics and mislead you about user engagement.

It's crucial to analyze quantitative data, like user logs and retention curves, to understand how your product is actually being used, rather than relying solely on user feedback.

Retention should be analyzed by looking at cohorts of users over time, assessing how many continue to use your product after signing up.

Cohort retention tracks the fraction of new users who continue using your product over time, providing a quantitative measure of user engagement.

Understanding the retention rates of both paying and free users is crucial for identifying growth opportunities and addressing potential issues in user engagement.

Visualizing cohort retention trends helps you understand how user engagement changes over time relative to the initial cohort size, allowing for better analysis of user retention. Cohort retention curves are essential for understanding user engagement over time, as they track the percentage of new users who return to use the product repeatedly.
