My App download is decreased dramatically in Google Play

Hello,
I have developed many app and game that are in Google Play. When I published my new application “Make Me Old” within in a week it was downloaded 5000 and in second week download increased to 7000. After second week, download decreasing and now this application is downloaded about 2500 only in a week. This incident happens with many of my application. Can any one suggest me how to increase download as it was in second week.

Thanks,

Some apps just fail harder than others. Not sure there’s much you can do!

Try expanding your App marketing efforts past the Google Play Store. If you aren’t getting the downloads you want from your Google Play search optimization, try creating a web page for your app and increasing your app’s online presence. A separate web page can give you much more room and creativity to display the features of your app.Check this out for more info on App Marketing
