Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.
The only difference with the offline middleman and affiliate business program is that the online affiliate does not need to get hold of the actual product to earn revenue. He doesn’t need to shell out money to buy the product that he has to sell. All he has to do is create a site that markets the products of the producer. Every time he makes a sale, the producer will take over to send the actual products, receive payments and extend customer support, when necessary. A special web-based script records this process and thus the affiliate is paid for every successful sale he makes.
