Best performing layouts

[amplify]

On Sedo, what have you found to be the best performing layouts? Does it depend on the site? I've been playing around with a clothing related site that receives ~ 100 type-ins/month and only receives about 8 clicks a month. Still excellent revenue per click (Avg. ~.50), but I would like to see a 15% click through rate at least (on this domain and others).

Any pointers?

Thanks
