I don't understand I keep getting a penny everyday and its not from clickthroughs because that shows up as zero. Its not from CPM either because there isn't anywhere near 1000 page impressions. Where are these pennies comming from?
It could still be CPM, you don't need a 1000 impressions to earn the odd cent as it would be pro rata (if that's the right wording). See the CPM rate was $1 you would only need 10 impression to earn a cent
Good to know, but if I double my unique impressions I don't get a second penny so its not exactly linear earnings.
Yay! I earned $0.02 from 50 impressions which is cool since impressions are easier to get then clickthroughs.
