1. What Is Affiliate Marketing?
Affiliate marketing is a performance-based business model where you:
- Promote products or services owned by another company
- Earn a commission for every sale or lead generated through your unique link
You don’t need to create products or handle customer service—just refer traffic or sales.
2. How Affiliate Marketing Works
Here’s the basic process:
- You join an affiliate programme
- Get a unique tracking link for a product
- Share that link via your website, social media, or email
- When someone buys through your link, you earn a commission
Most programmes use cookies to track referrals over 30–90 days.
