Setting up Experiment Segmentation and Distribution

Before You Begin

Before you start an experiment, you should have a very clear idea of who belongs in your experiment. 

A good question to think about before starting an experiment would be, "Considering the goals I'm trying to accomplish, who should be included in this experiment?"

With that in mind, you'll be able to send the right experience/experiment, to the right user, at the right time in order to test your idea and accomplish your goal! 

For more granular segmentation that is proprietary to your product or that has to do with a user's stage in their lifecycle, you can set custom user attributes which will help you target a specific set of users. Here are the docs for Objective-C, Swift, React Native, Android and JavaScript.

 

How to think about your segmentation

You should always be thinking about who will be included in your experiment. And remember that users may, at some point, fall outside of your experiment which could be a result of a variety of factors, in which case they will no longer be a part of the experiment. 

A clear example for this is if, say, your experiment was to include only users who are:

• on iOS
• using appVersion = 1.0.0
• have made 0 purchases

If a user made a purchase (so they have 1 purchase), that user will no longer qualify for your experiment.

If a user upgrades to appVersion 1.0.1, that user will no longer qualify for your experiment.

If a user switches to a new Android device and sells their iOS device, that user will never qualify for the experiment on the other device.

A simple way of thinking about your segmentation is that your filters are a net that you cast to include which users belong in your experiment.
