In 2025, everyone’s chasing quick wins and viral side hustles. But the most underrated way to make passive income this year is quietly helping people earn while they sleep, without posting reels or selling courses.
We’re talking about digital product affiliate websites. It’s not new, but it’s seriously slept on. Low upfront costs, no inventory, and once it’s set up, it can generate income for years.
Let’s dive into why this method is underrated — and how to start your own.
