I'm curious as to what others in the community do to analyze their downloads. Last month I had a wallpaper drop in downloads significantly overnight. In 48 hours time it went from 800 downloads average to less than 50. This particular wallpaper still has great ranking for the various search terms in the play store, though it is starting to drop after a month of crappy downloads. I'm curious, has anyone else experienced sudden changes in their downloads, and if so, how do you research and analyze what happened?
