Not only that, besides the moustache pic, but I never do CPM until testing CPC's CTR first. If you can get a .08 to .10 CTR then switch over to CPM as you'll get cheaper clicks. CPM is retarded with a low CTR.
Captain Obvious maybe, or maybe not.![]()
Any tips on figuring out what CPM cost you're going to be looking at for sustained impressions is?
