That gave me an idea, so I used my notebook I never used to login into AdBrite account, and I could see the ads! Seems like it's a protection against the click by the publishers themselves, using cookie... Interesting...
This is what is great about the sites with large traffic or huge traffic they can easily sell off their PPC or CPM banners for a fixed price . They charge anything which makes sure that they will get the same amount of money each month . WIthout having to see the network ads.
AdBrite CPM is garbage. I have their banner ads on my site for 3 weeks. With over 100,000 pageviews daily my income should be substantial with non-network interstitial and CPM banner ads. Yet I am still earning $6 to $13 a day. For instance if the ad CPM is $0.75 cent I should make at least $75 a day with the traffic I get. I will give them another week to get it together then I will remove their ads.
Now I have better idea why AdBrite is so much different in approach compare to BidVertiser and Adsense.
