Measuring retention is critical; if you don't have a product that retains users, you shouldn't focus on growth yet.

When evaluating cohort retention, focus on the overall shape of the retention curve rather than isolated metrics from specific time points. Be cautious when using analytics tools for measuring cohort retention, as they may not accurately reflect what you think they do.

Use tools like Mixpanel and Amplitude for retention analysis; they provide valuable insights into user engagement and retention over time.

It's important to choose meaningful actions for measuring user engagement; simply tracking app opens can lead to misleading retention metrics.

When product teams focus solely on metrics like engagement or dwell time, they risk neglecting qualitative aspects such as content quality and user satisfaction, which can lead to long-term retention issues.

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.

Using surveys to gauge product-market fit can be biased; instead, focus on measuring actual user retention.

Choose a time period for measuring cohort retention that aligns with how frequently you expect users to engage with your product, such as daily for social apps or weekly for utility apps.

When measuring cohort retention, track individual groups of new users over time instead of mixing all users together, which provides clearer insights into user behavior.
