hey guys, i have watched a youtube video of a guy showing how to buy android/iOS apps, and edit them, change background pictures... and add your AdMob, and then post them to App Store or Google Play, and you will earn money from admob ads. my question here what techniques you should follow to get your app to be a little bit popular, because if you bought this app many others did and they have posted them in the app stores, so that mean your app already duplicated even if you have edited just the pictures and make it VISUALY different from other apps !!, is there any techniques in marketing your app !! My second question, is anybody here used this method or similar, and have any earenings from it ??
