For me its a numbers game obviously, on average, For every 10 free joins I get, 1 signs up. As far as a time frame goes, most joins are within 20 to 30 min. of scanning the site. Once they run across that pic that looks real, and the info states that they live in the same area, thats when they want to know more. The average porn guy isnt seeking thru dating sites, like he or she would if it was hardcore. So most traffic, the is even going to put their email in, is probally truely seeking a companion. I feel that the after emails are very important to the company obviously and depending on how often and how well the emails are made, i feel its also good for the affiliate.
AAC does a great job with their email program, and I have made a killing with their
rev. share program and thats do to them sending the emails just to keep them interested.
