My site gets 1.8 million +/- page views a month. I've got Adsense, Media.net and Amazon CPM (which is going away in Sept.) I average $4000/month or so from those three. Should I be doing something more or different than using those three, soon to be two, networks? I'd rather not selling advertising spots, my site is kind of unique in the subject matter so finding companies to sell spots has never worked.
