If your willing to share any tips it be cool of you. I like to try and promote hostgator on my sites because they are low traffic but I get unusually high ctr because the 1 cent ads are really appealing looking but then people realize they have to buy a domain if they don't have one (and if they have a domain odds are they aren't looking for webhosting anyway) and that costs 15.00 dollars at hostgator and they leave. I've probably sent over at least 400 visitors without a conversion, and while I've sure 400 isn't that much, I would of hoped for at least one by now. I've toyed with the idea of trying to make some kind of landing page to explain getting a domain cheaper at godaddy and just using it on hostgator but that seems kind of complicated. So far the only commissions I've gotten was from referring people in real life.
