Affiliate Marketing Glossary

A comprehensive A-Z reference of affiliate and referral marketing terms. Whether you're launching your first affiliate program or scaling an existing one, this glossary covers every concept you need to know.

Affiliate

A partner who promotes a product or service in exchange for a commission on resulting sales or leads. Affiliates use unique tracking links to earn credit for conversions they drive.

Affiliate Agreement

A legal contract between a company and its affiliates that outlines commission rates, payment terms, acceptable promotion methods, and termination conditions.

Affiliate Dashboard

A portal where affiliates can view their performance metrics, track clicks and conversions, access promotional materials, and monitor earnings.

Affiliate Link

A unique URL assigned to an affiliate that contains a tracking identifier. When a visitor clicks the link and makes a purchase, the affiliate earns a commission.

Affiliate Manager

A person responsible for recruiting, onboarding, and supporting affiliates within a program. They optimize program performance and manage affiliate relationships.

Affiliate Network

A third-party platform that connects merchants with affiliates. Networks handle tracking, reporting, and payments but typically charge fees on top of commissions.

Affiliate Program

A structured marketing arrangement where a business rewards external partners (affiliates) for driving traffic, leads, or sales through the affiliate's promotional efforts.

API Key

A unique identifier used to authenticate requests to an affiliate platform's API. In Refgrow, API keys use the rgk_ prefix and are stored as hashed values for security.

Attribution

The process of identifying which affiliate or marketing channel deserves credit for a conversion. Common models include first-click, last-click, and multi-touch attribution.

Attribution Window

The time period after a click during which a conversion can be credited to the referring affiliate. Also called cookie duration or lookback window. Typical windows range from 30 to 90 days.

Chargeback

When a customer disputes a payment and the charge is reversed. In affiliate programs, chargebacks typically result in commission clawbacks from the referring affiliate.

Churn

The rate at which customers cancel their subscriptions or stop buying. High churn reduces the long-term value of affiliate-referred customers and impacts recurring commissions.

Click-Through Rate (CTR)

The percentage of people who click on an affiliate link out of the total who see it. Calculated as (clicks / impressions) x 100. A key metric for measuring affiliate content effectiveness.

Clawback

The reversal of a previously paid commission, typically triggered by a refund, chargeback, or subscription cancellation within a specified period.

Commission

The payment an affiliate earns for generating a qualifying action such as a sale, lead, or signup. Commissions can be a flat fee or a percentage of the transaction value.

Commission Override

A custom commission rate assigned to a specific affiliate that overrides the program's default rate. Used to incentivize top performers or negotiate special partnerships.

Conversion

A desired action completed by a referred visitor, such as making a purchase, signing up for a trial, or subscribing to a plan. Conversions trigger commission payouts.

Conversion Rate

The percentage of referred visitors who complete a desired action. Calculated as (conversions / clicks) x 100. Higher conversion rates indicate more effective affiliate promotions.

Cost Per Acquisition (CPA)

The total cost to acquire one customer through affiliate marketing, including commissions and program overhead. A key metric for measuring affiliate program efficiency.

Cost Per Click (CPC)

A payment model where affiliates earn a fixed amount for each click on their affiliate link, regardless of whether the visitor converts.

Cost Per Lead (CPL)

A payment model where affiliates earn a commission for each qualified lead they generate, such as a form submission, email signup, or free trial registration.

The ability to track a referred user across multiple devices (phone, tablet, desktop) and still attribute the conversion to the original affiliate link click.

Customer Lifetime Value (LTV)

The total revenue a business expects from a single customer account over the entire relationship. Higher LTV justifies higher affiliate commissions.

Deep Link

An affiliate link that directs the visitor to a specific page (like a product or pricing page) rather than the homepage. Deep links typically convert better than generic links.

Earnings Per Click (EPC)

The average earnings generated per click on an affiliate link. Calculated as total commissions / total clicks. EPC helps affiliates compare the profitability of different programs.

First-Click Attribution

An attribution model that credits the first affiliate whose link a customer clicked, even if they later clicked other affiliate links before converting.

Fraud Detection

Systems and processes designed to identify and prevent fraudulent affiliate activity such as fake clicks, self-referrals, cookie stuffing, or manufactured conversions.

Hold Period

A waiting period between when a commission is earned and when it becomes available for payout. Protects against refunds and chargebacks. Typical hold periods are 15-60 days.

Impression

A single instance of an affiliate link or banner being displayed to a visitor. Impressions are the broadest metric and the starting point for calculating CTR.

In-App Referral

Multi-Tier Commission

A commission structure with multiple levels where affiliates earn from their direct referrals (tier 1) and from referrals made by affiliates they recruited (tier 2+).

Multi-Touch Attribution

An attribution model that distributes credit across multiple touchpoints in the customer journey rather than assigning 100% credit to a single interaction.

One-Time Commission

A commission paid only once per referred customer, typically when the first purchase is made. Contrasts with recurring commissions paid on ongoing subscriptions.

Payout

The transfer of earned commissions to an affiliate's account. Payouts are typically processed on a schedule (weekly, biweekly, or monthly) after the hold period expires.

Payout Threshold

The minimum commission balance an affiliate must accumulate before a payout is processed. Common thresholds are $25-$100 to reduce transaction processing costs.

Performance Bonus

An additional reward given to affiliates who exceed specific targets, such as a set number of conversions or revenue generated within a given period.

Pixel Tracking

Postback URL

A server-to-server tracking method where the advertiser's server sends conversion data directly to the affiliate platform's server, without relying on client-side cookies.

Product-Specific Commission

A commission rate applied to a specific product or pricing tier, different from the program's default commission rate. Useful for varying margins across products.

Recurring Commission

A commission model where the affiliate earns a percentage of every renewal or recurring payment made by a referred customer for a set duration or indefinitely.

Referral

A visitor who arrives at a website through an affiliate's link or recommendation. In SaaS, this typically refers to a tracked visit that may lead to a signup or purchase.

Referral Code

Referral Link

A unique URL containing an affiliate's tracking code that attributes clicks and conversions to the affiliate. Also called an affiliate link or tracking link.

Referral Program

A structured system where existing customers or partners are rewarded for recommending a product to new customers. Often used interchangeably with affiliate program in SaaS.

Return on Investment (ROI)

A measure of profitability comparing the revenue generated from an affiliate program to its total costs, including commissions, software, and management time.

Self-Referral

When an affiliate uses their own referral link to make a purchase for themselves. Most programs prohibit self-referrals and use fraud detection to prevent them.

Sub-Affiliate

An affiliate recruited by another affiliate within a multi-tier program. The recruiting affiliate earns a percentage of the sub-affiliate's commissions.

Tiered Commission

A commission structure where the rate increases as affiliates hit performance thresholds. For example, 20% for 1-10 sales, 25% for 11-25 sales, 30% for 26+ sales.

Tracking Pixel

A 1x1 transparent image or JavaScript tag placed on a confirmation page that fires a request to the affiliate platform to record a conversion event.

Why Understanding Affiliate Marketing Terms Matters
