How can I start affiliate marketing with zero investment?

You can begin affiliate marketing without money by focusing on free traffic sources. Start a free blog using WordPress.com or Blogger, or create a YouTube channel. Share product reviews, tutorials, and honest recommendations. Post in relevant Facebook groups or forums, but avoid spamming. Consistency and value matter more than paid ads in the beginning.

I started affiliate marketing with Reddit and Quora answers. By genuinely helping people and inserting affiliate links only where relevant, I built trust and earned my first commissions. It’s slow, but possible without investment.
