[Help] Why my AdMob(WP8) RPM dropped everyday, from $0.79 to $0.02 within a week?

[Frank Wu]

Dear all,

I am new to AdMob. I published a windows phone 8 app using Admob, smart banner, refreshed every 60s. My impression is increasing everyday. However, my RPM dropping from $0.22 all the way to $0.02. Does anyone know what's the problem and how to fix it? Any tips will be appreciated!

Please see my screenshot for more details.

Great thanks,

Frank

Don't know if this would be related but my RPM has been dropping for several days now, maybe over a week. Yesterday for example was 30% lower than the week before and the week before was already lower. Conversely my pageviews yesterday were 20% higher than the week before.
