Affiliate marketing is a performance-based marketing strategy where you earn commissions by promoting products or services for other companies. You share affiliate links on your website, blog, or social media, and when visitors make a purchase through those links, you receive a commission. To get started, choose a niche that aligns with your interests and audience, and then join affiliate programs like Amazon Associates, ShareASale, or Commission Junction. Once enrolled, select products or services to promote and integrate affiliate links into your content. Successful affiliate marketers often create high-quality, relevant content and build trust with their audience. It requires time and effort, but with the right approach, affiliate marketing can be a lucrative way to earn passive income.
