Campaigns consist of three main concepts:
When certain events are registered, evaluate these rules and show these paywalls.
You can set the percentage of new users that see each paywall, and can configure no paywall (a.k.a. a holdout) to be shown for certain rules.
In this scenario, every time the
viewed_welcome_screen event is tracked, 50% of users will see the paywall, and the other 50% of users won’t see any paywall at all. Since the rule is
true, all users will match.
Setting a holdout is useful when you want to test the effectiveness of showing a paywall. In the above scenario, the developer uses the holdout to see whether adding a paywall on
viewed_welcome_screen increases or decreases transactions. The holdout group acts as a control which they can compare against.
Assignments Are “Sticky”
Once a user is assigned a paywall or a holdout within a rule, they will continue to see that assignment unless you reset assignments (by clicking the reset icon next to Assigned) or remove the paywall from the rule via the X button.
Remember: Changing a paywall’s percentage only affects new users. It doesn’t affect assignments for users who already saw that paywall.
You can also assign multiple events to the same campaign — assignments will be sticky regardless of which event was tracked.
Here’s an example with two events and two paywalls, where everyone sees a paywall:
In this scenario, both
load_feed events will trigger the campaign. 50% of users will see the first paywall, and 50% of users will see the second.
Here’s a more complicated example:
tapped_start_workout is registered:
- If the user has completed greater than or equal to 3 workouts, always shows a paywall.
- In all other scenarios, show a paywall 50% of the time.
