I have always wanted to know what requirements one must meet to have a developed app on Google Play store. I would love to have feedback from people who have developed their own apps and already selling them or offering them for free on the store. I would also like to know whether marketing an app through different related websites is really effective with so much competition around.
Well, you'd have to visit Google's developer site for the specifics. You can market through related websites, but really, you're going to want to create a top quality app that does something other apps don't do or don't do properly. Then you'll have to get everyone you can to download that app through whatever means necessary to start turning a profit from a paid app or ads in a free app.
