How Does Affiliate Marketing Work? The 4 Key Players
Affiliate marketing involves four main parties:
1. The Merchant
The merchant (also called the seller, retailer, or brand) is the company or individual that creates the product or service. They offer affiliate programs to help market their products.
Example: Amazon, Bluehost, or individual course creators.
2. The Affiliate Network
Some affiliate programs run through an affiliate network—a third-party platform that connects merchants with affiliates. It tracks sales, clicks, and commissions.
Popular affiliate networks include:
Note: Some companies like Amazon run their own affiliate program without a separate network.
3. The Affiliate
This is you—the marketer. You promote the merchant’s products via your blog, YouTube channel, social media, or email list.
You’ll receive a unique tracking link (referral URL) to monitor clicks and sales. Example:
https://affiliateprogram.com/product?id=123&ref=yourID

4. The Customer
The customer clicks on your referral link, purchases the product, and completes the affiliate cycle. The merchant makes a sale, and you earn a commission.
Affiliate links are tracked using cookies, which stay active for a set period (e.g., 30 days).
Types of Affiliate Marketing Programs
1. CPA (Cost Per Acquisition)
You earn a commission only when the customer makes a purchase. Most affiliate programs follow this model.
2. CPL (Cost Per Lead)
You get paid when someone signs up or submits their contact details—great for email opt-ins or free trials.
3. Revenue Sharing / Recurring Commissions
Earn recurring commissions from subscriptions, SaaS products, or memberships (e.g., ConvertKit, Teachable).
