My apologies if this is a stupid question, but how would I go about becoming an affiliate for a site? I see a lot of guides here that proclaim that you should do x and y and then leave your affiliate link for a site, but when I visit that site there's no clear specification on how to become an affiliate. Do I have to contact the site directly and ask? Is there a site that allows you to become an affiliate for other sites? Again, I apologise if this seems like a stupid question, but I can't find a clear answer.
