I have an iPad blog where I post news / information articles daily that gets about 300k uniques / month and 900k impressions. Currently monetizing with Adsense making $100-$120 / day. I want to further monetize it by selling ad space. Any ideas on good pricing / size structure? And where to go about selling it as my site does not get approved on buysellads.com
I may add iPad CPA offers as well.
