I want to begin advertise my app using mobile ad network as Airpush and so on.

Usually I work as an affiliate so I use an external tracker as MOBIT, Voluum and so on. So I can see from where the best traffic comes and to do optimization to get the most conversion (download of app).
Can you suggest me how to do it with my app, how I connect the Google store app so the download of the app will synchronize with the traffic I send to it ?
