I have an entertainment site with a pretty decent traffic that is generating about 40,000-50,000 impressions a day. We only monetize it via AdSsense and the clicks are pretty low paid and probably the best way to monetize it would be with CPM ads. So.. here's the question, do you guys know any good CPM networks? I'm not looking for extremely high CPM rates, I just want something that would pay me at least $1 per 1,000 impressions. It could be a banner network, a video player network and so on. Waiting for your suggestions. Thanks.
