How Taplytics Assigns Users Into Experiments

Taplytics offers two ways to segment users into Experiments:

  • Device-Based Bucketing (DBB)
  • User-Based Bucketing (UBB)

Device-Based Bucketing

Device-based bucketing ensures consistent experiment and feature flag behaviour across pre and post log-in user states where userID’s are not required or necessary.

Benefits:

  • Users are targeted based on their device:

    • For mobile devices, Taplytics sets a device id
    • For web applications, Taplytics sets a device id associated with the browser cookie
      This requires a standard, out-of-box implementation
  • Users always see the same experience on the same device

Considerations

Depending on how your users use and interact with your product, this implementation method does not guarantee a consistent experience across multiple devices.

For example, if the expected user behaviour is to access the platform on their mobile device as well as through their desktop, a consistent experience is not guaranteed because the assignment and distribution is on a device level.

Implementation

Device-Based Bucketing is the default setting and no additional setup is required.


User-Based Bucketing

User-based bucketing ensures consistent experiment and feature flag behaviour across devices with pre and post logged in user states where users are identified with a userID.

Benefits:

  • Users are targeted based on a unique userID

  • Users always see the same experience across devices in a logged-in state

  • User-based bucketing is the best option for true cross-platform optimization and attribution

Considerations

Applications must pass a unique userID for each user to Taplytics to ensure a consistent user experience. Also, there are additional Taplytics implementation steps.

The main consideration affects anonymous users who never log in and use multiple devices. It is possible these users will receive different pre-logged in experiences. In this use case, an anonymous user will have two unique IDs on different devices until they log in at least once on both devices. The pre-logged-in anonymous data will not be included in the logged-in user model.

Implementation

Users looking to leverage UBB will need to contact Taplytics support or your CSM to configure a project to the user-based bucketing setting.

Server-Side SDK (including Universal API) implementations must have user-based bucketing enabled on their project to provide consistent bucketing.

For Client-Side implementations, add a Start Option to your initialization code. You can find this info in the Start Options section of the SDK docs.
