Use Case: I plan on marketing iOS apps that I own & operate. I plan on marketing these apps on FaceBook and Google. I want to understand my funnel conversion by source. Meaning what is the install rate on FaceBook v. Google from start to finish.
Outside of the app economy I would simply pass a parameter in the URL to indicate source and the web application would suck it in. If I want to use an iTunes redirect URL how would I tracking which installs came from which source?
If it's a paid app, you can use the iTunes LinkShare affiliate program:

If it's not a paid app, you're out of luck without a heavy 3rd-party tracking system tracking click origin, and matching that to your internal app install ID process. Painful.
Since the introduction of App Analytics (introduced WWDC 2015) it is possible to track campaigns through the App Store.
From the docs:
As far as I know there is no way to do this. The analytics data Apple provides via iTunes connect is really pretty weak.
