About Game Event Tags

What are game event tags?

"Game event tags" are simple lines of code that you can add to your app in order to catalogue how your app is used.
When a game event tag is triggered, our SDK sends that activity to us along with the anonymous sdkID.

Nefta processes these first-party game events to classify sdkIDs into patterns of behaviour on an app-by-app basis (we never combine data from different apps). We serve ads based on the pattern of behaviour and their likelihood to interact with the ad creative. This is how we can pay superior eCPMs on users who opt-out of tracking.

Event tags:

Nefta has three types of events.

  • Progression events: The player "does" something in the game.
  • Receive events: The player "gets" something to their account or inventory.
  • Spend events: Something is spent from the account/inventory.
