Affiliate marketing is a performance-based marketing strategy where businesses reward affiliates for driving traffic or sales to their website through their marketing efforts. Affiliates typically promote products or services via unique links, and when a customer makes a purchase or completes a desired action (like signing up for a newsletter), the affiliate earns a commission.

This method offers several benefits. For businesses, it provides an affordable way to expand reach without upfront costs, as payment is only made for successful conversions. For affiliates, it offers an opportunity to earn passive income by promoting products they believe in, with no need for inventory or product development.

Common affiliate marketing models include pay-per-click (PPC), pay-per-sale (PPS), and pay-per-lead (PPL). The success of affiliate marketing relies on choosing the right products, building trust with audiences, and using effective marketing tactics like content marketing, email marketing, and social media promotion.

Overall, affiliate marketing is a win-win for both businesses and affiliates, offering a low-risk, high-reward way to generate revenue and grow brands.
