Porn Junkie,
I think most free site builders would agree that a very high percentage of your sales will come right from the index page. Usually the top of that page. Grab em by the balls and steer them to the sponsor tour with that ad space. As ponygirl pointed out, use text not graphics. It loads faster. For the text you use, talk to the surfer. What does the paysite have to offer that sets it apart from the rest? Does it have movies? Are they downloadable? ipod compatible? How many? Do they have the hottest %insert niche% women? At least that's what works for me.
You should try to make it to on the bench also. Mr. Mary Lou provides a wealth of information on his radio show. Last week was all about text!
