just wondering.

in general do you think adult webmasters test what sells and what their traffic clicks on, or do they just throw banners up and hope they stick with the visitors?

I'm starting to think it's the latter.

I was looking at a rather large site, been around since late 90s, last night offering ad space for sale and their rule was only html link with no PHP or variables in it, and only 1 banner, no rotation. All that for a nice couple grand a month!
