I got a site with about 5 mill hits a month, but my readers are not of the clicky kind. Then I guess I can make a few bucks with CPM. But what is/are the best CPM network(s)? Furthermore, is it possible to have several CPM programs running at your site at the same time, so that you dont get paid from only one company but maybe 2 or 3? Yes, I know people hate popups/unders, but it`s a crappy site anyway. Still got readers though.
