What is Affiliate Marketing?
Affiliate marketing is a performance-based marketing model where businesses reward third-party partners (affiliates) for driving traffic or sales through their marketing efforts.
In simple terms:
-
You (the business) offer a product or service
-
An affiliate promotes it via blogs, YouTube, email, social, etc.
-
You pay only when the affiliate drives a conversion (sale, lead, or click)
Key Players in Affiliate Marketing

Merchant (Advertiser/Brand) – The company that wants to sell more products or services
-
Affiliate (Publisher) – The promoter who earns commission
-
Affiliate Network – A platform that connects merchants and affiliates (e.g., ShareASale, CJ, Impact)
-
Customer – The end user who clicks the affiliate link and makes a purchase
