Look for patterns

Look at the customer behavior of both your good and bad customers. Doing this will help you to identify successful user journeys.

Follow the 5-step process

1. Put a list together of all your product's features.
2. Pick a list of your most successful customers and analyze what features they used early on, continue to use regularly, and stopped/didn't use.
3. Write down what features got adapted and didn't.
4. You need to find the behaviors that, when performed, best correlate with continuing to use your product for an extended period of time.
5. You want to lead with the features that get people to upgrade.
