Why It Ranks #3

Near-zero startup cost, truly passive once content ranks, and pairs perfectly with any content-based side hustle. The compounding effect of evergreen affiliate content is hard to beat.

The Full Breakdown

Affiliate marketing is how you turn content into revenue without building a product. You recommend products you actually use, include your affiliate link, and earn a commission when someone buys through it. Amazon Associates, ShareASale, Impact, and dozens of other networks make it trivially easy to get started — the hard part is building the audience that trusts your recommendations.

I use Amazon affiliate links on this site. When I recommend a book or a piece of gear, I include my affiliate tag (glenbradford-20) and earn 4-8% on qualifying purchases. It is not life-changing money on its own, but combined with content that ranks in search engines, it becomes a consistent passive income stream that grows as your content library grows.

The key to affiliate marketing in 2026 is authenticity. Readers can smell a cash-grab review from a mile away. Only recommend products you have actually used. Write honest reviews that include the downsides. Build comparison pages that genuinely help people make decisions. The affiliates who succeed long-term are the ones whose audience trusts them — and trust is earned by being honest, not by cramming affiliate links into every sentence.
