The explainer

What is affiliate marketing?

In one sentence: you earn a commission when someone buys a product through your unique, trackable link. It's performance-based, free to join, and — done honestly — one of the most accessible ways to earn from things you already recommend.

The mechanics

How it actually works.

Four moving parts, no smoke and mirrors. The brand only pays when a real sale happens — which is why it's free for you to join.

1

You join free & get a link

Sign up for a program (free), and you're issued a unique tracked link or code tied to your account.

2

You share a recommendation

You post a review, a comparison, a tutorial — or hand someone a QR code — pointing to a product you actually use.

3

Someone clicks & buys

A cookie or code attributes the sale to you, within the program's tracking window.

4

You earn a commission

The brand pays you a percentage (or flat fee) of that sale — once you clear the payout threshold.

What defines it

Single-level. Free. Honest.

Affiliate marketing is defined by four things — and the absence of a few others that signal a scam or MLM.

  • Performance-based. You earn only on real sales or qualified leads — not on activity or recruitment.
  • Free to join. Legitimate programs never charge you to participate.
  • No inventory. You don't buy, hold, or ship anything. You point people to the brand.
  • Single-level. No downline, no team to recruit, no cut of other people's "sign-ups."
Speak the language

Key terms, defined.

You'll see these on every program's terms page. Knowing them helps you compare offers — and spot which ones are actually worth your time.

Commission
Your cut of a sale — a percentage (e.g. 1–10% on Amazon, up to ~30% on creator platforms) or a flat fee per referral. Recurring commissions pay every billing cycle.
Cookie window
How long after a click you still get credit if the person buys. Amazon's is just 24 hours; ClickBank's is 60 days. Longer windows mean more attributed sales.
EPC
Earnings per click (sometimes per 100 clicks). A quick way to compare how well an offer converts your traffic into money.
Payout threshold
The minimum balance before you get paid. Awin's is ~$20, ShareASale's ~$50, LTK's $100. Lower thresholds get you paid sooner.
Attribution
How a sale is tied back to you — usually a cookie, a referral code, or a deep link. In-person codes and QR codes carry attribution into real life.
Affiliate network
A marketplace (ShareASale, CJ, Impact, Awin) that connects you to many merchants in one dashboard, with consolidated tracking and payouts.
Straight answers

Common questions.

No. Affiliate marketing is single-level — you earn on real sales through your link, with no downline, no recruitment, and no buy-in. MLMs pay partly for recruiting others and usually require purchases. Here's the full comparison.
Yes. Legitimate programs are always free. A join fee, "starter kit," or mandatory monthly purchase is a red flag — walk away.
Most beginners earn $0–$1,000/month in year one. First commissions come in days–weeks with an audience, or 2–4 months from scratch; consistent income at 6–12 months. The "$8,038/month average" is skewed — median is closer to $1,200–$2,500. See the honest breakdown.
No website required. Apps like Mavely, Flip, and ShopMy let you share to existing networks with no or low follower minimums. A website or email list helps long-term, but you can start with your phone today.
Yes — the FTC requires a clear, conspicuous disclosure placed with your recommendation. "Paid link" works; "affiliate link" alone may not be clear enough. Read the disclosure guide.
