My app recently reached its 1M download, thought it would generate more daily download and actually it was. It booted up to 12895 on Mar 30 but then it massively went down to 9399 on Mar 31 and 5177 on April 1.
:(:(:(:(:(:(:(
I haven’t done anything, no updating or change any store listing. Any one knows why? Is it possible that Google Play changed its app ranking algorithm recently after its new policy?
Google Play doesn’t update downloads at the same hour everyday. One day they might update the downloads at 10 AM and publish them at 10PM and the next day they might update downloads at 4PM and publish them at 6PM.
Also, I don’t know what timezone they use but daylight saving time (that happened this weekend in lots of parts of the world) might have also influenced your downloads a bit.
Obviously, dropping in rankings is a very important factor, too.
Use appannie.com to track your ranking in the last days and see if you see a big drop in rankings.
