Affiliate Marketing: How It Works & Disclosures

Affiliate marketing is often described as a way to “earn while you sleep.”

That description skips the part that determines whether the business works: the reader has to trust the recommendation, click at the right point in the buying process, complete an eligible action, and remain eligible under a program’s attribution and payment rules.

Traffic matters. Intent matters more.

A small comparison page that helps a qualified buyer choose between two products can be more valuable than a high-traffic article whose readers have no reason to purchase anything.

How Affiliate Marketing Actually Works

The basic affiliate relationship involves:

• merchant or advertiser: the company selling the product or service;
• affiliate or publisher: the person or business sending potential customers;
• tracking system or network: the technology that records referrals and applies program rules; and
• customer: the person who completes the qualifying action.

You receive a unique link or identifier. When a reader clicks, the tracking system records information needed to determine whether a later action should be attributed to you.

Common commission models include:

The merchant’s agreement defines which actions qualify. Do not assume two programs using the same phrase—such as “30% recurring”—calculate or pay commissions the same way.

Understand Attribution Before You Forecast Revenue

Attribution decides who gets credit when a customer interacts with more than one marketing source.

A program can use:

• browser cookies;
• server-side tracking;
• publisher or campaign IDs;
• coupon codes;
• account-level referral data; or
• a combination of methods.

The attribution window is the period during which a qualifying action can potentially be credited to your referral.

It is not a guarantee that every purchase during that period belongs to you.

Credit can be affected when:

• the customer clicks another eligible affiliate link;
• the program gives another channel priority;
• a coupon or promotion changes attribution;
• cookies are unavailable or deleted;
• the customer switches devices;
• the product is excluded from commissions; or
• the program uses rules other than simple last-click attribution.

Amazon Shows Why Program-Specific Rules Matter

Amazon Associates currently uses a session that generally begins when a customer clicks an Associate’s Special Link and ends at the first of several events, including 24 hours passing, the customer placing an order for a non-digital product, or the customer clicking another Associate’s Special Link.

Amazon’s current help materials say qualifying items added to the shopping cart within that 24-hour period can still generate commission if the order is completed before the cart expires, generally within 90 days, subject to the rest of the program rules.

Amazon also updated its Commission Income Statement effective April 14, 2026. Among the changes, a product now must be shipped to, streamed or downloaded by, and paid for by the customer within 180 days of purchase to qualify under the updated rules.

Know the Difference Between Pending, Approved and Paid Revenue

An affiliate dashboard can show a commission long before that money belongs in your checking account.

A typical path can be:

Programs use different status names, but the underlying distinction matters.

A commission may be reversed because:

• the order was canceled;
• the product was returned;
• payment failed;
• the lead was duplicate or invalid;
• the order was identified as fraudulent;
• the purchase violated program terms;
• the customer did not complete a required step; or
• the advertiser rejects the transaction under its validation rules.

Payment can also be delayed by:

• a minimum payout threshold;
• monthly closing cycles;
• merchant approval periods;
• the network waiting for advertiser funding;
• tax or identity verification;
• payment-method setup; or
• currency and international payout processing.

For bookkeeping and planning, track at least:

• gross tracked commissions;
• approved commissions;
• reversals;
• payable balance;
• cash received; and
• the date each payout arrives.

Place FTC Affiliate Disclosures Where Readers Will See Them

Affiliate commissions create a financial relationship that can affect how readers evaluate your recommendation.

FTC guidance says that relationship should be disclosed clearly and conspicuously.

The FTC gives a straightforward example:

The wording does not have to match that sentence exactly. It has to communicate the relationship in language ordinary readers can understand.

What Is Not Enough?

FTC guidance specifically says consumers may not understand that the phrase “affiliate link” means the publisher gets paid when someone purchases through the link.

Likewise, a “Buy Now” button does not itself explain the financial relationship.

The FTC says the closer the disclosure is to the recommendation, the better.

A disclosure can be inadequate when it is:

• only on an About page;
• only in general Terms and Conditions;
• behind a vague hyperlink;
• below the recommendation or link where the reader would need to continue scrolling;
• hidden among unrelated hashtags or links; or
• otherwise easy to miss.

Social, Video and Audio Need Format-Appropriate Disclosure

FTC guidance says social-media disclosures should be hard to miss and placed with the endorsement itself.

For video endorsements, FTC guidance says the disclosure should be in the video rather than only in the description. The FTC notes that disclosures presented in both audio and video are more likely to be noticed.

For image-based stories or similar formats, the disclosure should be superimposed where viewers can see and read it.

A platform’s built-in “paid partnership” tool can be useful, but do not assume a platform label automatically satisfies every disclosure obligation in every context.

Follow Program Rules in Addition to FTC Rules

FTC compliance is only one layer.

Every affiliate program can impose its own rules on:

• where links may appear;
• paid search;
• email;
• coupon or deal sites;
• browser extensions;
• social platforms;
• link cloaking or redirects;
• trademarks and brand bidding;
• price display;
• product images or API data;
• incentivized clicks;
• self-purchases;
• offline promotion; and
• required disclosures or wording.

Amazon Requires Its Own Associate Identification

Amazon’s current Operating Agreement requires Associates to clearly and prominently state:

Amazon’s help guidance separately says Associates should also provide a legally compliant disclosure with affiliate links. It gives examples of link-level disclosures such as “paid link,” “#ad,” or “#CommissionsEarned,” depending on the format and context.

That is a good illustration of why a site’s general FTC disclosure does not automatically replace merchant-specific obligations.

Create Affiliate Content Around Reader Intent

The best affiliate content helps the reader make a decision they were already trying to make.

Useful formats can include:

• product comparisons;
• hands-on reviews;
• “best for” guides with clear selection criteria;
• tutorials where a recommended tool is genuinely part of the workflow;
• alternatives guides;
• pricing and feature comparisons;
• case studies;
• setup guides; and
• resource pages for a defined audience.

Avoid turning every informational article into a list of unrelated purchase links.

Ask:

• Does the recommendation answer the reader’s current question?
• Have I explained who the product is for?
• Have I explained who should choose something else?
• Are important drawbacks visible?
• Are prices, features, and eligibility claims current?
• Would I still recommend this product if the commission disappeared?

Do Not Let Commission Rates Control Editorial Rankings

FTC’s 2023 Endorsement Guides include examples addressing review websites that receive affiliate payments.

A review or ranking can become misleading when compensation influences the ranking in a way readers would not expect and that relationship is not appropriately disclosed.

For an editorial site, keep a documented methodology where practical:

• what factors are evaluated;
• how products qualify for inclusion;
• which claims are independently verified;
• how sponsored or affiliate relationships are disclosed; and
• whether compensation affects placement.

If compensation does affect placement, do not present the result as though it were an independent editorial ranking.

Measure Affiliate Profit, Not Just Conversion Rate

Clicks and conversion rate are useful, but they do not show the complete economics.

Then compare the revenue with your content costs, paid promotion where used, software, contractor expenses, and time spent maintaining the program.

Diversify Merchant Risk

An affiliate program can change its:

• commission percentage;
• attribution window;
• eligible products;
• traffic rules;
• payout method;
• geographic availability; or
• entire affiliate program.

If one merchant generates most of your business income, a policy change can materially affect revenue even when your traffic remains stable.

Diversification does not mean linking to five merchants everywhere. It means avoiding a business model that fails when one partner changes the rules.

Treat Affiliate Revenue as Business Income

Affiliate commissions are generally taxable income.

IRS guidance says commissions and fees received for services are generally included in gross income, and self-employed business activity is commonly reported through Schedule C when applicable.

Keep records showing:

• each network or merchant;
• payments received;
• foreign-currency conversions where relevant;
• business expenses;
• software and hosting;
• contractor costs;
• advertising;
• refunds or clawbacks affecting your accounting; and
• tax forms received.

Do not assume that income is tax-free because a network did not issue a Form 1099.

For qualifying nonemployee-compensation payments made in 2026, the general federal Form 1099-NEC reporting threshold is $2,000, but information-reporting rules and the taxability of income are separate questions.

Affiliate marketing can produce revenue long after content is published, but the business is not “set and forget.” Links break, products change, commission terms move, disclosures need to remain visible, and old recommendations become inaccurate.

The durable advantage is reader trust. If the affiliate link helps the reader make a better decision, monetization can fit naturally. If the link exists only because the commission is attractive, the economics may work briefly while the editorial value deteriorates.
