Get paid to register for free, sounds good, but rare in these days. Better to find a free to register program that pays based on high conversion to sales, far more lucrative than getting a few cents or bucks on registrations alone. If you are going to drive traffic to any site, wouldn't you want it to convert for maximum return on your investment of time and money driving traffic to a site. To each their own, but I can't see wasting time on low dollar low conversion free registrations. I look for high conversion to sales affiliate programs so I know I get the most bang for the buck.
As example, everyone watches TV, and everyone hates their cable or satellite provider, never mind the high price of subscriptions every month, so given this is the largest consumer base in the world as everyone has more than one TV, this free registration affiliate converts to sales with a $60. commission because everyone saves on average a thousand dollars a year, so why would anyone bother with free registration payouts without having a hgh conversion rate? Streaming FREE-PPV TV, Movies and Sports is a booming new industry and I have never seen as much interest in the affiliate marketing since gambling sites back in the 90's before government squashed niche by blocking U.S. bank credit processing. Made a small fortune on affilate gambling deals for a few years, but as with everything, the gov. will find a way to screw it up. lol
