I've been reviewing SaaS tools and affiliate programs for about three years now. Most of them promise the world and deliver a trickle of pocket change. So when I decided to figure out whether you could realistically earn from affiliate marketing without a single follower, I treated it the same way I treat any product review — I set up a test, tracked the results, and reported what actually happened.

Let me walk you through exactly what I did, the numbers I saw, and the verdict on whether this is worth your time.

The Big Lie: You Don't Need an Audience (Here's What Actually Matters)

I called BS on this idea after running a six-month test.
Here's the thing most people miss: when I'm hunting for a new API tool, I don't open Instagram and look for influencer recommendations. I type into Google. I read two or three articles.

I tested this exact pattern. Over the past quarter, I built three simple review articles targeting search queries I identified through basic keyword research. None of them
