I just made this, so we'll see how it does. I am trying to earn more than ten cents a week, which is what adsense paid me on 2,500 page views. Anyway, what my setup does is show CPM ads. What makes it cool is, the first time it shows an ad from pay-ads.com, the second time, it shows an ad from hotPTP, and then thats it. Two ads, then no more ads Eventually I'll ad a cron to wipe the database - or use a datestamp so I can have stats and still get traffic from repeat visitors. This also lets me see some interesting stuff, like whether the ad companies are full of shit with their numbers, and what companies are the best to go with, and how many pages people load before they leave my site. Feel free to recommend other CPM companies - either ones you know are good or ones you want to check out.
Sounds good however I think that some of those pay per impression not per ip. If it is ip good plan what would make it better is after the cpms you show adsense then every 24hrs the list is cleared and you show cpms 3 times. Shmoe
