I am running Casale as my top tier, then I use interclick and a combination of TMP Express and Realtech Networks for the bottom catchall. I also use adsense but that seems to perform consistently enough to satisfy me. I run adsense on the pages with content, and CPM ads elsewhere. Now after reading the forums here a good bit one explanation I can come up with is that the 150k a month are repeat visitors. The site is somewhat like a forum but not quite. I usually only hear that explanation for CPC programs though. even from casale I am never getting over $0.19 eCPM (this month its $0.14 so far). Another thing that might it might be is that I mainly run Leaderboards and banners, with a Medium rectangle on one page. Needless to say that while I am satisfied that the site is generating revenue, the numbers just dont seem to be adding up like they should. Anyone have any recommendations? I was rejected by fastclick and tribal fusion so those are out. From reading around it seems like a $0.30 eCPM is a more sane number, but is this with the usual Leaderboard, Skyscraper, Rectangle config?
