I do know AdSense's method - people click the ads and then you make money. But is AdBrite basically like that? When people click the ads, you make money? Or is it like, people PAY you to put their ads on your site, and it doesn't matter whether anybody clicks them or not.
Its both, people CAN purchase ads on your site through Adbrite, but if no one buys, adbrite will display relevant ads on your site.
