What is affiliate marketing — and why does it matter?
May 6, 2026 · Allison Santana
By now, most of you understand how I make money online. To the rest of you, this may be something new.
If you've spent any time reading blogs, watching YouTube, or scrolling through social media, you've almost certainly encountered affiliate marketing. You just may not have known it by name. That little "shop my favorites" link in a caption? An affiliate link. The "use code XYZ for 10% off"? Affiliate marketing. It's everywhere, and yet a lot of people still aren't quite sure how it actually works.
So let's break it down.
The simple version
Affiliate marketing is a way for people (bloggers, creators, everyday shoppers with a platform) to earn a commission by recommending products or services. When someone clicks your unique link and makes a purchase, you earn a small percentage of that sale. The brand gets a customer. The reader gets a recommendation they (hopefully) trust. You get compensated for the referral. Everyone wins.
Think of it like being a really good friend who always knows the best finds, except now there's a system in place that credits you when your recommendation actually leads to a purchase.
How it works, step by step
Here's the basic flow behind every affiliate transaction:
Creator joins an affiliate program
Gets a unique tracking link
Reader clicks the link
Reader makes a purchase
Creator earns a commission
The tracking happens automatically through cookies (small bits of data that tell a brand "this sale came from this specific link." Most programs have a cookie window of 24 hours to 30 days, meaning if someone clicks your link and purchases within that timeframe, you get credit for it).
What kinds of things get promoted?
Almost anything you can buy online has some kind of affiliate program attached to it. Books, kitchen tools, software subscriptions, skincare, courses, organizational products — if a brand sells it, there's a good chance they have a program. Amazon Associates is probably the most well-known, but there are hundreds of platforms and individual brand programs out there.
Is it just about the money?
Honestly? For most creators who are doing it well, no. The best affiliate content is rooted in genuine enthusiasm for what's being recommended. Readers are smart! They can tell the difference between a forced plug and something a person actually uses and loves. The financial incentive works best when it's secondary to real, honest recommendations.
That's the approach I try to take here. Everything I link to is something I've actually read, tried, or found genuinely useful in my day-to-day life. The affiliate structure just means I can keep creating content around the things I care about while being transparent about how this all works.
What it's not
Affiliate marketing isn't a get-rich-quick scheme, and it's not about selling people things they don't need. At its worst, it can feel spammy and transactional. At its best, it's just an extension of a trusted recommendation. The kind of recommendation you'd text a friend without thinking twice about it.
It also doesn't cost the reader anything extra. The commission comes from the brand's marketing budget, not from a markup on the product price. So clicking an affiliate link is genuinely just a way to support a creator at no cost to you.
