What is Affiliate Marketing?

Affiliate marketing is a performance-based business model where you earn a commission by promoting other people’s or companies’ products. You make money every time someone makes a purchase (or completes another predefined action) through your unique affiliate link.

Key parties involved:

1. Merchant (Advertiser): The company selling the product (e.g., Amazon, Bluehost, Nike).

2. Affiliate (You): The person promoting the product.

3. Consumer: The person who clicks your link and makes a purchase.

Example: You recommend a fitness product on your blog. When a reader clicks your affiliate link and buys it, you earn a commission (e.g., 10%).
