SITE IS CLOSED. NEVER MADE MONEY THERE
DomainHop is another paid domain parking service which can monetarize your unused domain. Domain Hop pays the highest of a $4 rpm (4 cents for every 10 visitors who view your site) or their pay-per-click rate when a person clicks on a link. They will quit paying the $4 rpm if your site falls under $2 rpm over two weeks on its own. This model seems to have been designed to keep them competitive at a time when they dont appear to have the ad inventory that other sites do.
