Affiliate marketing is an advertising model in which a brand pays third-party content creators to generate traffic and leads for the brand's products or services. Content creators often run a blog or produce video content. They promote the company in their content and are given a unique link to drive their audience to. Then, they are paid a commission for the value of the traffic driven to that link or sales made through it.

Affiliate marketing is a useful tool for businesses who want to reach a wider, established audience through a creator the audience is already familiar with. Affiliate marketing is a billion-dollar industry, and it operates in both B2C and B2B spaces. Return on investment for affiliate marketing can be very high since the company essentially outsources marketing and selling to the affiliate.
