Affiliate Marketing is commission-based marketing.

This type of marketing is often commission based. The simplest way to explain affiliate marketing is through an example, so here goes. Have you ever signed up to a club and the owner of that club says “if you recommend us to a friend and that friend then signs up, we will reward you”? Affiliate marketing works in a similar way. An affiliate site will promote another companies product, accompanied by a link to the site of the merchant of that product, which could result in a user purchasing that product. The merchant is happy because they have gained a sale and therefore rewards the affiliate site for the part they had to play in the sale.
