I looked at your site and your sponsor links outnumber your gallery links 2:1. Skimming aside, the easiest way to raise your outclicks is to give the surfers more to click on. I am not familiar with the features of the X-3 script, but most scripts offer a link tracking option that will show you which links are clicked the most/least, take the most popular links and move them to the top of the list, i.e. your surfers like teen links the most, fill the top of your gallery list with teen links. As for skimming, I would suggest 70%-75% as the skim ratio, where 70%-75% will go to the actual gallery. If you go lower that that you start to enter the cj2 world, where most of your links will be blind
Hope this helps.
