[Useless]

Certain sponsors will convert during the rush of traffic on a new site, others won't. Finding which will convert quickly is a trial and error effort. Bookmarker traffic, which can be a big part of that initial rush, has seen it all and though they do buy, it takes that special something to convert them to the sale. (Think nasty, exotic, different.) SE traffic is better, assuming the surfer can actually locate the item they searched for buried somewhere within a link list's listings. SE traffic directly to your free sites is ideal, but it's really goddamn difficult to compete with older sites in the SEs.
