RPM of €8.77! WTF! my Admob stats are:
Estimated earnings
$226 usd
Impressions
259k
Request RPM
$0.86 usd
That depends on a target country.
I have games that became popular in Latin America and RPM is in a $0.2-$0.6 range.
For the US, Canada and the UK I usually get $4-$15 RPMs.
For shopping apps (think deals, coupons, savings) I've seen up to $50 RPM.
