Affiliate marketing is one of the most popular ways to earn money online, offering benefits for both businesses and individuals. It works on a simple performance-based model: affiliates promote a product or service and receive a commission when a sale, lead, or action is completed through their unique referral link.For businesses, affiliate marketing is a cost-effective growth channel. They only pay when results are achieved. For affiliates, it provides an opportunity to earn passive income without creating their own products.The process involves three main players: the merchant (company), the affiliate (promoter), and the consumer. Affiliates use websites, blogs, social media, email marketing, or ads to share links. When someone clicks and buys, a commission is credited automatically.Overall, affiliate marketing remains a powerful strategy due to its scalability, low cost, and accessibility for beginners.amazon attribution measurement
