Hi i got a small suggestion if you take like 5 cpm programs and rotate them it would almost be like 5k hits are 5k uniqe so 5 times the money i assume
not exacly most programs pay for uniqe only so if you have like 20k bulk and 3k-4k uniqe a day you earn more
i think what he is saying is most CPM pays for unique so if you can rotate 5 programs and assuming your visitors visits page 5 times or 5 other pages with cpm then you would get paid for all 5 instead if you ran only 1 program you would only get paid once. sounds like good idea to me.
Could work if you have a high traffic site where the impression to unique ratio heavily favors the former.
