I don't hear or read too much about people making money with cost per impression ads on their website. AdSense seems to be the popular choice. Is CPM not worth it? I'm thinking about testing some CPM networks to see how they do compared to AdSense. Is anyone having success using CPM ads on their website? How would a site with around 1,500 visitors and 2,500-3,300 page views per day do? I am also going to guess Google will not let you use AdSense with this, so it would be one or the other.
