Affiliate marketing is all about selling a product or service for a commission using affiliate programs. Affiliate marketing works by choosing the program and sign up for its affiliate program. You will have different merchant products to choose from, where you get an affiliate link to promote on your blog as an ad or embed in a post. Internet marketing is easy to start up and you do not need to have a product to sell before becoming an affiliate. It’s a good way to earn a passive income doing what you love most.
