What Is Affiliate Marketing? (Plain English)
How affiliate marketing works, examples, and how creators actually get paid

Affiliate marketing is when you recommend a product, the person buys through your link, and you earn a commission. No inventory, no customer service.
How It Works
1) Join a program (Amazon Associates, Impact, individual SaaS programs). 2) Get a unique tracking link. 3) Share it. 4) When someone buys, you earn 1–50% commission.
Real Example
A YouTuber reviews a $1,500 standing desk with their Amazon link. 100 viewers buy. At 3% commission, that's $4,500 in commissions from one video.
How the money actually moves
You send someone to a merchant through a link carrying your tracking ID. A cookie is dropped on their device. If they buy within the cookie window — 24 hours on Amazon, 30 to 90 days on many software programmes — the merchant attributes the sale to you and pays a percentage. Nothing is added to the buyer's price; the commission comes out of the merchant's margin, which is why it exists at all. Payment usually lands 30 to 60 days after the month closes, because returns have to clear first.
Where the money actually is
Commission rate and order value pull in opposite directions, and beginners consistently pick the wrong end. Physical goods pay low single-digit percentages on small baskets. Software and hosting pay 20-50%, sometimes recurring for the life of the subscription. Financial products pay flat bounties. The rate on its own tells you nothing: 3% of a $600 appliance beats 40% of a $15 ebook, and a 25% recurring commission on a $50-a-month tool beats both within a year. Work out earnings per click, not commission percentage.
| Structure | Assumed conversion | Per 1,000 visitors |
|---|---|---|
| 3% on a $600 item | 2% | $360 |
| 40% on a $15 ebook | 3% | $180 |
| 25% recurring on $50/mo | 1% | $125/mo, ongoing |
| $100 flat bounty | 0.5% | $500 |
The disclosure rules are not optional
US FTC guidance requires that a material connection — which a commission is — be disclosed clearly and conspicuously, close to the link and before someone clicks it. Not in a footer, not on a separate page only. Amazon's operating agreement goes further: associates must state their participation, must not display price, star rating or review count outside Amazon's own dynamic widgets, and must not put affiliate links in email, ebooks or PDFs. Programmes close accounts over this, usually without warning and usually withholding unpaid commission.
Why most attempts earn nothing
The failure is almost never the programme choice. It is publishing pages nobody is searching for, or pages for a search term where the buyer has already decided and does not need a recommendation. The pages that earn answer a question someone asks while genuinely undecided, and answer it well enough that the recommendation is credible. That means the useful content has to come before the links, not after them — which is also what every programme's own guidance says, for the same reason.

Frequently Asked Questions
How does affiliate marketing work?+
You link to a merchant with a tracking ID. If someone buys within the cookie window, the merchant pays you a percentage of the sale. The buyer pays the same price either way — the commission comes out of the merchant's margin.
Do I need a website to do affiliate marketing?+
You need somewhere you can publish and disclose properly. A site is the most durable option because it earns from search over time. Most social platforms and every email programme have restrictions, and Amazon in particular prohibits affiliate links in email, ebooks and PDFs entirely.
How much do affiliates make?+
It depends almost entirely on earnings per click rather than commission rate. A 3% commission on a $600 purchase pays more than a 40% commission on a $15 ebook. Recurring software commissions compound; one-off physical product commissions do not.
Do I have to disclose affiliate links?+
Yes. US FTC guidance requires a clear, conspicuous disclosure near the link and before the click — a footer note is not enough. Amazon additionally requires a statement of participation and prohibits showing price, ratings or review counts outside its own widgets.
