- Start Event: The user event defines the user cohort for retention analysis.
- A/B test first exposure : The entire unique user exposed to the A/B test. All of user exposed to the A/B test first time will be counted even without any further actions
- Adding additional Start Event : The user who caused a certain event after their first A/B test exposure will be only counted.
- You can use the filter function for the first exposure event or additional event after the exposure.
- Adding a Start Event feature is supported for Pro plan and above.
- Return Event : The return event is a criteria to determine how many of the users in the cohort retained
- You can use the filter function for a return event.
