Sometimes on my Adsense reports I get something like a penny like if I check it after midnight. I don't understand where the money comes from because it doesn't show any click throughs. On top of that it can't be CPM revenue because I don't get 1000 impressions that early in the morning.
Yay! I earned $0.02 from 50 impressions. I know thats not a lot, but impressions are easier to get then clickthroughs.
Yes it is DP's CPM ads. I daily aveage a 0.20$ for DP's CPM ads. Sometimes i also get some Good Clicks in DP too.
With a channel you can know were the earnings are comming from. If you got no clicks and you have money its CPM (or earnings going up with no more clicks).
That probably means that the click is not a valid click. Its a cheated click, a click you did, or a click done on someone's computer where your adsense reports were also checked. So if you check your adsense revenue, you can't click your banner or it won't count.
