Affiliate marketing is a way of making money online. It’s really a simple concept. When you are an affiliate marketer, you promote a product, service, or site for a business, and you as a publisher get rewarded for doing so.In most cases, you find products related to your niche and offer them on your website or blog. You promote the products and post a link on your site where they can purchase the products. Then, when someone follows that link to buy something, you earn a commission. The commissions can be either a percentage of the sale or a fixed amount. You’ve seen links to other sites when you’ve read other people’s blogs. These links make the blogger money.
