The problem with promoting ONE site is that a lot of your visitors aren't looking to join THAT site so you won't make any sales from them and your ratio is going to look bad. If you are promoting a handful of sites (even just a text link in your header/footer will make sales) then you have a better chance of your visitors finding what they're looking for and your ratios for each site/sponsor will look better since you're not dumping all them onto one site.
