You find a product let's say "Panavision 3D", you register a domain name with the keywords. Then you start working on SEOing the domain name until it's on top 10 on google, which is not that hard to do. Or course you are not going to market "ipad 2"... which is almost impossible to get there. Instead market expensive products that are not so known. Then you contact the company and explain them that you have this domain name or site ranking well in google when people search for their product and you can sell them the site. I'm still in the process of testing this, but has anyone experience with this method? Maybe it's an old method but I don't see too much people talking about it. Any ideas?
