Affiliate marketing is one of the oldest forms of marketing wherein you refer someone to any online product and when that person buys the product based on your recommendation, you receive a commission.
Affiliate marketing is the process of earning a commission by promoting other people's (or company's) products. You find a product you like, promote it to others, and earn a piece of the profit for each sale that you make. It is a good way to promote your website through other people. It only helps to generate leads for your business.
