How to Start Affiliate Marketing in 2025: A Comprehensive Guide

Affiliate marketing is a performance-based business model where individuals, known as affiliates, promote products or services of other companies and earn commissions for driving sales or leads. This model has gained significant traction due to its low startup costs, scalability, and potential for passive income. Affiliates utilize various channels—blogs, websites, social media platforms, and email marketing—to share affiliate links. When a consumer clicks on these links and completes a desired action (like making a purchase), the affiliate earns a commission.
