What is affiliate Marketing?
The basic principle behind affiliate marketing is simply selling or promoting someone else's product or service in return for a commission. This is probably the most popular business model that is adopted by those new to Internet marketing as it is considered to be the lowest cost business model when starting on the Internet.

This business model exists in many forms, and are commonly called Affiliate Programs. You join the Affiliate Program that the Merchant is operating that is selling the particular product you are interested in promoting. The most common types of programs are as follows:

1. Pay per click - commission will be paid by the merchant for each visitor to his website.
2. Pay per lead - you are paid for each lead delivered to the merchant's website.

3. Pay per sale - you are paid for each sale completed at the merchant's website.
Each one of the above returns a certain payment for delivering the click, lead, or sale. By far the largest number of businesses online work on the Pay per Sale system

It may sound very simple, but like everything in business, there is nothing to reap if you do not sow the seeds. The difference is that you have less tasks to perform since there will be no costs associated with product development, sales copy, delivery or the associated costs for payment or follow-up servicing of customers. These costs are for the merchant. Your main task will be the promotion of the service or product.
