Affiliate marketing basics, in plain English

What the words mean, how you get paid, and how to stay honest with your audience. About a 10-minute read.

What affiliate marketing is

A company gives you a special link (your affiliate link). When someone clicks it and buys or signs up, the company pays you a commission. The company runs the program, decides who is approved, tracks the sales and pays you. You share honest recommendations with your audience.

Be realistic: most affiliates earn little or nothing at first. Income depends on your audience, how well a product fits them, and the company's terms, which can change at any time.

Commission types

TypeWhat it meansExample wording
RecurringYou earn again each time the customer pays, for a set time or as long as they stay."30% recurring for 12 months"
Percent per saleA share of a one-time purchase."20% of each sale"
Flat per saleA set dollar amount when someone buys."$50 per paid plan"
Flat per sign-upA set amount when someone creates an account, even a free one."$2 per free sign-up"
Flat bountyA set amount for a specific action the company defines."$100 per qualified lead"
HybridA mix, such as a percent plus a sign-up bonus."30% per sale + €0.20 per free sign-up"

Read the details: "up to" usually means the top tier, which new affiliates may not reach. Recurring commissions usually stop if the customer cancels or gets a refund.

When someone clicks your link, the company saves a small marker (a cookie) in their browser. The cookie window is how long a purchase still counts for you after that click.

Example: with a 30-day window, if a reader clicks your link on May 1 and buys on May 20, you get credit. If they buy on June 5, you usually don't.

Most programs credit the last affiliate link clicked before the purchase. Cookies can also be lost if the buyer clears their browser, switches devices or uses a privacy blocker, so tracking is never perfect. A longer window helps when people take time to decide. See programs with 90+ day cookies.

Payouts, minimums and holds

Networks vs. in-house programs

Some companies run their own program (in-house). Others use an affiliate network such as impact.com, PartnerStack, CJ or Awin. A network gives you one account and dashboard for many brands, but each brand still approves you separately and sets its own terms. Every listing on Green Gator Affiliator shows which route a program uses and links to the official terms.

Getting approved

Telling your audience (disclosure)

In the United States, the Federal Trade Commission (FTC) expects you to tell people when you earn money from a recommendation. In its own words, the disclosure should be clear and conspicuous, and "the closer it is to your recommendation, the better."

"I earn a commission if you buy through links in this post, at no extra cost to you."

Not legal advice. Green Gator Affiliator isn't a law firm. Rules differ by country and platform, and some programs have their own disclosure rules. Read the FTC's guidance (linked below) and ask a lawyer if you're unsure. For wording you can copy for each platform, see How to disclose affiliate links.

Common program rules

Taxes

Affiliate commissions are income. In the US, the IRS says income is taxable even if you don't receive a tax form for it. A US company may send you a Form 1099 when it pays you at least a certain amount in a year. For payments made in 2026, that amount is $2,000. You still report income below that amount.

Not tax advice. Green Gator Affiliator isn't an accountant. Tax rules depend on where you live and your situation. Talk to a tax professional, especially before your first payout.

Red flags

If a listing on Green Gator Affiliator looks wrong or suspicious, open it and tap Report incorrect information.

How to start

  1. Pick products you already use and would recommend to a friend.
  2. Check fit: make sure the program allows where you post. Use the filters on Find Programs.
  3. Read the official terms: commission, cookie window, payout minimum and rules. Each listing links to them and shows when we last checked.
  4. Apply to two or three programs to start, not twenty.
  5. Track everything in My Programs: stage, dates, your link, promo codes and notes. Make QR codes for print or video.
  6. Disclose clearly every time you share a link.
