What is affiliate marketing and how does it work?
The basic model
A merchant (the seller) creates an affiliate program. You (the affiliate) sign up and get a unique link to their product. When someone clicks your link and buys, the merchant pays you a commission. The tracking is done by cookies or similar technology, so the merchant knows the sale came from you.
This is performance-based: you only get paid when a desired action happens, like a purchase, a sign-up, or a free trial. That makes it low-risk for you because you do not pay to join most programs. It is also low-risk for the merchant because they only pay for results.
Common ways it works in practice
Affiliates usually promote through content: blog posts, YouTube videos, social media posts, email newsletters, or podcasts. For example, a tech blogger might write a review of a laptop and include an affiliate link to buy it. A personal finance site might recommend a credit card and earn a commission for each approved application.
Commission structures vary. Some programs pay a percentage of the sale (e.g., 5–30%), others pay a flat fee per sale or lead (e.g., $5–$100). Some use a two-tier structure where you also earn from affiliates you recruit. Payment thresholds and schedules differ—many pay monthly once you reach a minimum balance, often $10–$100.

Common mistakes
- Confusing affiliate marketing with pyramid schemes or MLM—it is not about recruiting.
- Assuming all programs pay the same; commissions and cookie lengths vary widely.
- Forgetting that you must disclose affiliate links to comply with FTC rules.
