Here is what affiliate program is about.
Let’s say you’re in the market for a new camera. You search the Internet to find reviews for your favorite brands. After reading some reviews, you’ve decided that you’re ready to buy. On one of those reviews, you click a link that leads to a product listing and you buy the camera.
The link that you clicked on to buy the camera is a perfect example of affiliate marketing. When you bought the camera, the person who promoted the link earns a commission. This is affiliate marketing in a nutshell: earn commissions by promoting someone else’s products.
Affiliate marketing comes from many channels: reviews, banner ads, product promotions, and social media. Promote links through as many channels as possible to reach a larger audience.
