I've an arcade games site and trying to squeeze some extra $$ from it, would anyone know the answer to the above question? Thanks
It seems to be around $1 - $5 cpm from ad network providers. I have a few good ones listed on my site that pay around that way so that's how I know, plus I also work for an affiliates directory so I have seen many cpm popunder ad networks and other affiliate programs in my time of working for it.
