Do You Actually 'Sell' Your Sponsors Paysites Or Just Put Links Up?

I was wondering how many of you folks actually sold the sponsors paysites that you were promoting rather than just putting up a link or a banner for the sites the program offers?

Do you go out of your way to sell a specific sponsors paysite to your surfers or do you list a selection of sites in the niche and leave it at that, allowing the surfer to click through to the sponsors tour without any marketing on your part at all?
