I have an idea in which I have to list something but it will be an android application. So from what kind of methods I can earn through it. I can generate leads by capturing email and other info of the user but any other ways? What kind of advertisement should be there while user is on the app and it should not be tacky so that's what I'm concern about. I'll be okay with less CPA but I want some other methods too. OVERALL I'm looking for the revenue model for this online listing thing was searching internet and BHW too, I got something about OLX and QUIKR but it was not that I want so thought to post. Anyone can guide ?
