So what's your average eCPM with Googles AdSense. If possible, please post some details on the type(s) of sites your running. I'll go ahead and get this ball rolling... My eCPM is $1.82 and I successfully run a few arcade sites and try to run a few low traffic medical sites.
One of my sites is performing at $30 eCPM, another at only $5... It's all about hitting those specific niche markets.
I get a decent amount of traffic (about 15k pageviews per day) but I only get about 25 clicks worth $5 or so. Roughly $.33 eCPM Wish I could get it to something decent, but I have other ways to make money
