free hosted galleries (FHG) are most important, to us, when promoting others from our free sites.
No FHG = not intertested!

Hardcore tours and banners (yes, also hardcore) are most important when promoting others from our exit consoles and the other few limited locations.
Softcore = poor sales!

Also, and equally as important as the above is detailed stats - if the sponsor runs some of them weirdo periods or does not give the affiliate control of reports (dates, traffic type, referring URLs etc) they usually get pushed down the list, so far, I usually do not bother.
(Yes I know, not a promotional 'tool', to some)

Of course, the first and foremost important area of concern is dah BIG PEE PEE!
No big wieny = no traffic!
(I am talking about big dick specific or 'themed' sites! Not sites which happen to have some guys with big dicks.)
Yah sure, there are a few exceptions ... A FEW!
