The correct way of doing data-driven growth requires data from surveys, user behavior, and experiments. Survey data will help you to look at your product from the perspective of your users.
Use surveys to find out why people drop off or advance to the next page.
Sometimes asking users about what almost prevented them from continuing is better than asking those who dropped off.
Use data from the survey to do experiments.
Even when you find out that there is something wrong about your app, always confirm it with data from A/B tests.
Make surveys as user-friendly as possible.
It’s easy to make annoying ones.
