Wealthy Affiliate (WA) is not just about making affiliates. The affiliate program of WA is not the main part of the program, that is just a sidekick. Instead of trying to make tons of referrals in WA, try to focus on learning the lessons provided by WA so that you can learn to create your own website in your own subject of interest and make money from that by applying with affiliate programs like Amazon or with advertisement networks like Google AdSense and so on.
The ads in affiliate programs are linked to company websites and are referred to as affiliate links. Affiliates generally have to apply for the affiliate programs, though the majority of the affiliate programs cost nothing to join. When an online visitor click the affiliate link, the visitor is redirected to the advertiser's website and if the customer/visitor makes a purchase, the affiliate is then paid a commission.
