AdMob request RPM is $0.00... Why?
So I have 2 published games for android (Burger Hop and Ninstar) and I've been using admob to monetize them. The first few days I made about $0.6 dollars, but today that stopped. My request RPM dropped to 0 and I haven't made any revenue. Why is this?
P.S. I am still getting impressions, but not any earnings.
