Here’s a memo on how to track campaigns with Google Analytics in iOS apps.

For implementation methods, please refer to the above sites.

Campaign tracking cannot be completed within the app alone - it requires opening Safari browser once after the initial launch.

Sometimes you might see apps with strange behavior during first launch - they’re likely gathering information about which channel the download came from.

Personally, I dislike this behavior, so I decided not to use Google Analytics for campaign tracking.

That’s all from the Gemba.
