If you want to promote a product or service on your website, you need to sign up for the affiliate network that the company works with. Or you can sign up to several networks and decide which products you want to promote. They give you affiliate links, which is how they track where sales came from. You can place those links on your website, on YouTube, or social networks. When people click on them and buy the products or services, you are promoting through your link. When your audience takes the desired action, you get a commission.
Some affiliate networks offer Cost Per Action (CPA) programs. This means that the desired action is not always buying a product or service. It can be filling out a form, downloading a freebie, or opting in to receive a newsletter.
Affiliate marketing is a great way for a business to get organic traffic and increase conversion rates.
