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?
