💼 What is Affiliate Marketing?

Affiliate marketing is a performance-based marketing model where you earn a commission by promoting other people’s (or companies’) products.

You don’t need to create a product.
You don’t need to ship anything.
You just share a special trackable link—and when someone buys using that link, you get paid.

Affiliate marketing is bigger than ever before. According to recent estimates:

  • The global affiliate marketing industry is projected to reach $17 billion+ by the end of 2025.
