I'm new to this. Recently I read an article on business2.0 about domainers and suprised one domainer can "manage" thousands of websites. I check some of them, some of the links on the page are overture or google adsence(very few), most of them seem from a backend php or cgi program. Adding ads to one site is not a big deal, adsense probably is the best way, coz you have ur content. But I can't imagine how to make 5K sites like this. Too many questions, can I find a Domainer 101 somewhere?
