Key takeaways
- Look up a term by category instead of opening ten tabs.
- Money terms separate the payout model (CPA) from the result (conversion) and the metric (EPC).
- Tracking terms decide whether a sale is credited; check cookie window and attribution rules.
- Compliance terms matter: disclose material connections and mark paid links properly.
- Program terms change; check the date on the official page before you join or promote.
The short answer: what this page covers
An affiliate marketing glossary is a plain-English list of the terms you meet in program agreements, network dashboards and analytics reports: affiliate, publisher, advertiser, CPA, EPC, cookie window, disclosure and more. This one groups 80 terms so you can look up a word, understand it, and get back to work.
If you have ever had ten tabs open just to decode one program page, this page is for you. Start with the category that matches your confusion: roles, money, tracking, compliance or operations. Each entry is short on purpose. Where a term touches a rule, we point to the official source and tell you to check the current page, because program terms change.
Start here if you're choosing tools. If you are comparing hosting, funnel builders and email tools, open our dated feature-and-pricing comparisons before you buy: hosting comparison, funnel builders, and email tools. They show current signup prices and tell you what to skip. No annual-plan push before you can test.
What to skip right now: Skip tools that force an annual plan before a free trial. Skip 'done-for-you' funnels that promise hands-off results without showing real work. Skip any review that can't show dated pricing or hides drawbacks.
The wider process is covered in our guide to how affiliate marketing works. Use this page as the dictionary you keep beside it.
Affiliate marketing glossary: core roles and program terms
These are the people and pieces you meet before money enters the conversation.
People and pieces
| Term | Plain English |
|---|---|
| Affiliate | The person or business that promotes someone else's product and earns a commission when a qualifying action happens. |
| Affiliate marketing | Performance-based marketing where an advertiser pays an affiliate for traffic or sales. |
| Advertiser (merchant) | The company that owns the product or service being promoted. |
| Publisher | Another word for the affiliate in many networks; the party that publishes the promotion. |
| Affiliate network | A platform that connects advertisers, publishers and tracking in one place. |
| Affiliate program | The advertiser's scheme for paying affiliates, with its own rules, links and payout terms. |
| In-house program | An affiliate program run directly by the advertiser rather than through a third-party network. |
| Affiliate manager | The person who runs the program, approves affiliates and answers policy questions. |
| Offer | The specific product, trial or action an affiliate can promote. |
| Vertical | A broad market category, such as finance, health or home. |

| Tracking link | A link that sends clicks through a network or platform so the action can be recorded. |
| Deep link | A link that goes to a specific product or page, not just the advertiser's home page. |
| Landing page | The page a visitor sees after clicking; it should match the promise in the link. |
| Creative | The banner, image, text or video a program gives affiliates to use. |
Commission, payout and money terms
Money terms are where most tab-opening happens. Separate the payout model (how the advertiser pays) from the result (what happened) and the metric (how you judge it). Our guide to affiliate commission types goes deeper on CPA, revenue share, recurring and tiered deals, and what EPC means in affiliate marketing explains why network averages can mislead beginners. Our guide to pending vs approved commissions explains why a dashboard number is not money yet.
Payout models and payout status
| Term | Plain English |
|---|---|
| Commission | The payment an affiliate earns for a qualifying action. |
| CPA | Cost per action or acquisition; a payout model where you earn a set amount when the visitor completes a defined action. |
| CPL | Cost per lead; you earn when a visitor submits a form or meets a lead definition. |
| CPC | Cost per click; often an advertising cost, but some programs pay per click. |
| CPM | Cost per thousand impressions; usually an advertising buying metric. |
| Revenue share | A commission calculated as a percentage of the sale value. |
| Recurring commission | Commission that can repeat when a customer renews or keeps paying. |
| Tiered commission | A rate that changes when you hit a volume or performance threshold. |
| Flat fee | A one-off payment for a specific placement or action. |
| Bounty | A one-off bonus for a defined action, such as a sign-up. |
| Conversion | The desired action, such as a sale, lead or trial. |
| Conversion rate (CR) | Conversions divided by clicks or sessions; the share of visitors who complete the action. |
| EPC | Earnings per click; commission divided by clicks. |
| AOV | Average order value; total sales divided by number of orders. |
| ROAS | Return on ad spend; revenue divided by ad spend. Useful if you buy traffic. |
| Pending commission | Commission recorded but not yet approved; it can still change. |
| Approved commission | Commission the advertiser or network has accepted under the program's rules. |
| Reversed commission | Commission removed after a sale is cancelled, returned or found invalid. |
| Paid commission | Commission that has been sent to you under the program's payment schedule. |
| Payment threshold | The minimum balance a program requires before it pays out. |
| Net terms | The payment delay a program sets, such as payment after a period ends. |
| Chargeback | A reversal of a payment, often after a customer dispute; check how the program handles it. |
Tracking, attribution and analytics terms
Tracking terms decide whether your click is remembered long enough to earn credit. Our guide to affiliate cookie duration and attribution windows explains the timing, and UTM tags and sub-IDs shows how to label traffic so reports make sense. Google's Analytics help says you should use utm_source, utm_medium and utm_campaign when you add campaign parameters [3].
Tracking and analytics
| Term | Plain English |
|---|---|
| Cookie | A small file a browser stores so a site or network can recognise a visit. |
| Cookie duration / cookie window | How long a program's tracking remembers your click after it happens. |
| Attribution | The rule that decides which touchpoint gets credit for a conversion. |
| First-click attribution | Credit goes to the first link or ad a visitor clicked. |
| Last-click attribution | Credit goes to the last tracked click before the conversion. |
| Click ID | A unique identifier attached to a click so the network can match it to a sale. |
| Sub-ID | An extra label you add to a tracking link to separate traffic sources; check what your network supports. |
| UTM parameters | Tags added to a URL to label source, medium and campaign [3]. |
| Postback URL | A server-to-server call that tells one system a conversion happened. |
| Tracking pixel | A small code snippet that fires when a page or action loads. |
| Server-side tracking | Tracking handled between servers rather than only in the browser. |
| Click fraud | Fake or invalid clicks that can waste budget or distort reports. |
| Deduplication | The process of removing duplicate conversions so one sale is not counted twice. |
| Cross-device tracking | Matching a click on one device to a conversion on another. |
| Session | A visit period counted by analytics; a session can include several page views. |
| Referrer | The page or platform that sent a visitor to your link. |
| Direct traffic | Visits with no identifiable referrer; often typed, bookmarked or untagged. |
| Organic traffic | Visits from unpaid search results, not ads. |
Compliance, links and disclosure terms
Compliance terms are not the boring part. They decide whether your recommendation is clear and whether your links are marked the way Google expects. The FTC's Guides concern endorsements and testimonials in advertising [1], and Google documents rel values for outbound links [2]. Our FTC affiliate disclosure examples and guide to rel sponsored, nofollow and link cloaking go deeper.
Disclosure and link-marking
| Term | Plain English |
|---|---|
| FTC Guides | The Federal Trade Commission's Guides Concerning Use of Endorsements and Testimonials in Advertising; they address how endorsements and testimonials are treated [1]. |
| Material connection | A connection that could affect how readers weigh your recommendation, such as money or free products; the FTC's guides include a section on disclosure of material connections [1]. |
| Affiliate disclosure | A clear statement that you may earn a commission from links on the page. |
| Endorsement | Under the FTC Guides, a message consumers are likely to believe reflects a party other than the advertiser [1]. |
| Testimonial | A statement about someone's experience; the FTC says it treats endorsements and testimonials identically in enforcement [1]. |
| Sponsored link | A link that is an advertisement or paid placement; Google says mark it with rel=sponsored [2]. |
| Nofollow | A rel value that tells Google not to associate your site with the linked page or crawl it from your site [2]. |
| UGC link | A link in user-generated content such as comments or forum posts; Google recommends rel=ugc [2]. |
| Paid link | A link bought or paid for; Google says mark advertisements or paid placements with rel=sponsored [2]. |
| Influencer disclosure | A clear notice when a creator has a material connection to a brand. |
| Affiliate agreement | The contract between you and the program; it includes the rules you must follow. |
| Program policies | The extra rules a program incorporates into its agreement. |
Program rules and operations terms
Program rules and operations terms are where a promising side project can stall. Read the current agreement, not a screenshot from a forum. For example, Amazon's Associates Program Operating Agreement was updated October 15, 2025, and it incorporates Program Policies by reference [4]. That date is a prompt to check the live page before you join or promote. Our 12 clauses to read in an affiliate program's terms is a practical companion.
Program rules in practice
| Term | Plain English |
|---|---|
| Prohibited traffic | Traffic sources a program forbids, such as incentivised clicks or misleading placements. |
| Trademark bidding | Using a brand's trademark in paid search; check the program's terms before you bid. |
| Coupon policy | Rules on coupon sites, extension tools and claiming codes you do not have. |
| Email policy | Rules on promoting affiliate links by email, including consent and unsubscribe requirements. |
| Data privacy | How you collect, store and use visitor data; check the program and the law that applies to you. |
| Affiliate dashboard | The program or network screen where you see clicks, conversions and payments. |
| Network EPC | An average earnings-per-click figure reported by a network; useful context, not a promise for your site. |
| Dayparting | Scheduling ads or promotions for particular times of day. |
| Retargeting | Showing ads to people who already visited your page or clicked your link. |
| Funnel | The sequence from first visit to conversion. |
| A/B test | A comparison of two versions to see which performs better. |
| Sub-affiliate | An affiliate who promotes through another affiliate's link or network; rules vary. |
Your one-page glossary lookup checklist
When a new term stops you, do not open ten tabs. Use this checklist. It is deliberately short enough to copy into a notes app.
- Where did I see it? Program page, network dashboard, analytics report, forum or course. Write the source and the date.
- Which category is it? Role, money, tracking, compliance or operations. The category tells you whether it affects payout, credit or risk.
- What does the program's own page say? Copy the sentence and note the date checked. Program terms change [4].
- Does it change the money? If yes, write the formula or condition in your own words.
- Does it change tracking? If yes, note the cookie window, attribution rule and any sub-ID you need.
- Does it create a compliance job? If yes, add a disclosure or link-marking task to your publishing checklist.
- Who can answer it officially? Program support for program rules; a qualified tax professional for tax questions; the official documentation for platform rules.
Then use this decision table:
| If the term is about... | Check this first | What to write down |
|---|---|---|
| Payout | The program's commission page and current terms | Payout model, rate, qualifying action, approval rules |
| Tracking | The network's tracking guide and your analytics setup | Cookie window, attribution rule, sub-ID and UTM labels |
| Compliance | The FTC Guides and the program's policies | Disclosure wording, link rel value, restricted claims |
| Payment | The program's payment schedule | Threshold, net terms, pending vs approved status |
| Traffic | The program's prohibited traffic rules | Allowed sources, email rules, trademark limits |
Copy the table into a note and fill it in for each program you join. That single habit does more than memorising 80 definitions.
Worked example: EPC, CR and cookie window together
Illustrative example. Suppose a program pays a 10% revenue share. A customer buys a $50 product. Commission = $50 x 10% = $5. Your link received 200 clicks and produced 4 sales. Conversion rate = 4 ÷ 200 = 2%. Total commission = 4 x $5 = $20. EPC = $20 ÷ 200 clicks = $0.10.
Now add a tracking assumption. For this illustration, assume the program lists a 30-day cookie window and last-click attribution. A click on day 1 that leads to a sale on day 20 is inside the window; a sale on day 40 is outside it. A second affiliate who clicks later may get credit under last-click rules, depending on the program's actual terms. Check the current terms before you plan around a number.
What does this teach? EPC is not a magic score. It combines commission, conversion rate and click volume. A high EPC on a network dashboard can come from traffic or offers that are not available to you. Use the arithmetic on your own numbers, and label it as an estimate. This is arithmetic, not a promise of earnings.

How to use a glossary without wasting money or trusting the wrong advice
Here is the honest part. A glossary cannot tell you whether a hosting plan, funnel builder or email tool is worth your budget. It also cannot remove the risk that you pick a program that changes its terms or rejects your traffic. What it can do is help you read the words correctly before you spend.
We do not claim hands-on reviews of every tool on this site. When we describe a definition or a rule, we point to the official source where one exists. The FTC's Guides are the reference for endorsement and testimonial rules [1]. Google's documentation is the reference for rel values [2] and UTM parameters [3]. Amazon's operating agreement is the reference for Amazon's program rules, and it shows an update date of October 15, 2025 [4].
As noted above, some links are affiliate links; buying through them may earn us a commission at no extra cost to you. That does not change the definitions here, and it is not a reason for you to buy a tool you have not compared. Before you pay, check the current price on the signup page, read the refund terms, and ask whether the free plan or a cheaper tool covers your first month.
If you are comparing tools, make a two-column note: what the tool must do for your first site, and what it costs after the intro offer. If a review cannot tell you either, close the tab. Our affiliate program terms checklist and product due-diligence checklist are better next reads than another list of best tools. And if a term affects tax or law, ask a qualified professional; this page is general education, not legal or tax advice.

Frequently asked questions
What does affiliates mean in marketing?
In marketing, affiliates are independent promoters who send traffic to an advertiser and earn a commission when a defined action happens. They are also called publishers in many networks. The advertiser sets the rules, the network or platform may handle tracking, and the affiliate is responsible for honest promotion. If you recommend a product and may earn money from it, disclose that connection clearly [1].
How do you write an affiliate disclaimer?
Say plainly that you may earn a commission if someone buys through your links, and name the relationship without hiding it in a footer. Keep it in plain language, and check the current FTC guidance and your program's rules [1]. Do not rely on a vague affiliate links label if a normal reader would not understand it.
What are the big 3 niches in affiliate marketing?
There is no official big three. Beginners often hear about finance, health and home or technology because those categories have many products and searches, but that does not make them easy or right for you. A better test is whether you can explain a product honestly, find real questions people ask, and keep up with the program's rules. Pick a niche you can serve for months, not a label someone else chose.
What is trending in affiliate marketing?
Trends change too fast for a glossary to settle. For program rules, check the date on the official page, because agreements are updated [4]. Treat any trend as a question to verify, not a reason to buy a new tool.
What is the difference between CPA and EPC?
CPA is a payout model: you earn a set amount when a visitor completes a defined action, such as a sale or lead. EPC is a metric: commission divided by clicks. A program can have a high CPA and a low EPC if few clicks convert. Use CPA to understand the deal and EPC to compare your own traffic. Do not compare network EPC figures as if they were promises for your site.
