To simplify, An Affiliate marketer can be called a middleman, You are going to promote/sell products or services that you do not own and get commissions from it. It is now famous because of numerous online shops that is looking for an affiliate marketer. They do not ask much needed requirements, and even people that has no experienced from it can actually qualify. I wanted to try it as well but I am afraid that it might not suits me since I don't really have people that I can consider subscribers, even my SNS account are only limited with few friends and families.
