The Android app store will rank apps by how often they have been downloaded, and how often they have been downloaded recently. Almost all apps will show persons the exact stats on how many times one app has been downloaded. If a business wants to increase the amount that their app is downloaded, they can simply pay persons to download it. Most persons will download the app, and then delete it right away. These kinds of downloads can usually be purchased for only a couple of dollars. It is also possible to contact firms that specialize in generating thousands of app downloads for a couple of cents a piece.
