Promoting mainstream products on adult pages
 

is not probably a good idea. But how about this order? Adult page -> my own landing page with affiliate links -> final product(s) |pimpin I am not probably 1st who comes with this idea, just curious...

I make more money promoting my own non-adult goods on adult sites than I do promoting adult goods on adult sites. But I use a "sponsor" who allows this (myself!) so I don't have to go through the rigmarole with an intermediate landing page.

Also I create basic clean blogs using feeds, put ads on them then a link to them from my adult sites. For example this one:
