Affiliate Marketing Glossary: What Do the Most Important Terms Mean?

An affiliate marketing glossary is a reference list explaining the key terms publishers use every day, from settlement models such as CPA, CPL and CPS to metrics like CR, CTR and EPC. Knowing this vocabulary in 2026 lets you read campaign conditions correctly, compare offers and avoid the mistakes that block payouts in any affiliate network.

This guide gathers more than 100 affiliate marketing terms grouped by theme — models, metrics, tools, traffic, GEO and account safety. Return to it whenever a term in a campaign description is unclear.

What you'll learn from this article:

• what the core settlement models — CPA, CPL and CPS — and payout terms mean,

• which metrics (CR, CTR, EPC, ROI, ROAS) show if a campaign is profitable,

• what MyLead tools such as Content Lockers, Smartlinks and HideLink do,

• how GEO, Tiers and traffic types influence your earnings.

What is affiliate marketing and who are the key players?

Affiliate marketing is a performance-based model in which an advertiser pays independent publishers a commission for a defined result — a sale, a lead or an install. An affiliate network such as MyLead connects both sides: it aggregates programs, supplies tracking links and tools, and handles payouts. The publisher focuses only on promotion and earns per conversion.

The model runs in a clear loop: the advertiser submits an affiliate program to the network, the network shares it with publishers, and each publisher promotes it through a unique link. Every click and conversion is recorded automatically. If you are new, start with our guide to affiliate marketing for beginners or this professional view of what affiliate marketing is.

Core roles and objects in every affiliate program:

• Advertiser — a brand that promotes its products through an affiliate program to gain customers at a lower cost than traditional media such as TV.

• Affiliate network — an intermediary like MyLead that organizes programs, controls traffic quality and settles payments between the advertiser and the publisher.

• Affiliate program — a form of cooperation (also called a campaign or offer) that a publisher joins to promote a brand's products or services.

• Offer — a single product or service available in the network for promotion through affiliate links.

• Campaign — either all marketing activities promoting a product, or, in affiliate terms, a specific affiliate program.

• Promotion — spreading affiliate links among your audience to earn a commission for each acquired customer.

• Publisher (affiliate) — the person who earns money by promoting affiliate programs with their unique links.

• Customer (end customer) — the person who completes the required action: a purchase, a registration or another conversion.

• Mentor — an experienced guide who shares proven promotion techniques; at MyLead you can use mentorship support for free.

• MyLead — an affiliate network founded in 2014 that lets anyone earn online regardless of age, education or background.

What do CPA, CPL, CPS and other settlement models mean?

A settlement model defines the exact condition a publisher must meet to get paid. The three core models are CPA (payment for an action), CPL (payment for a lead) and CPS (payment for a sale). MyLead also runs COD, PPI and IVR variants, so always check which action a campaign rewards before you promote it.

• Settlement model — the rule that determines what the network pays you for; MyLead offers CPS, CPL, CPA and more.

• CPA (Cost Per Action) — you earn after the customer completes a set action, such as taking a loan, making a deposit or reaching a game level.

• CPL (Cost Per Lead) — you earn for acquiring a lead, usually a registration or a filled contact form; common in dating, lottery and contest offers.

• CPS (Cost Per Sale) — you earn when the customer buys a product, most often in e-commerce; the rate is usually a percentage of the purchase.

• COD (Cash On Delivery) — you are paid when a customer orders by phone and pays on delivery; the package fee is required for the commission.

• PPI / CPI (Pay/Cost Per Install) — you earn each time a user downloads and installs an app; learn more about the PPI model.

• IVR (Interactive Voice Response) — programs settled per minute of a paid phone call; the longer the call with the consultant, the more you earn.

Which terms describe leads, conversions and payouts?

A lead is a person who leaves valid data, a conversion is any completed action the advertiser pays for, and your commission is the reward for that result. Between the action and your money sit verification steps — hold, validation and acceptance rate — that confirm traffic quality before MyLead releases the payout.

• Lead — a person who left their data or correctly filled in the contact form on the sales page.

• Conversion — a user's completed action that brings measurable value, such as a sign-up, app download or purchase.

• Commission — your remuneration for mediating a transaction, usually a fixed amount or a percentage of its value.

• Configuration — the affiliate link you generate; the first one is created automatically when you gain access to a program.

• Acceptance rate — the percentage of leads ready for payout compared with all leads you acquired.

• Cap / Lead cap — the maximum number of leads an advertiser accepts from a campaign in a set period.

• Hold — the time the advertiser needs to check the quality of the conversions you generated.

• Validation — verification of data reported in the network against the advertiser's system; contact MyLead support for the next validation date.

• Baseline (BL) — used in gambling campaigns: the amount a player must spend to count as active; it is not the same as a deposit.

• Deposit — in gambling and investment campaigns, the minimum a customer must pay to start playing or investing — often $250 in investment programs.

• DOI (Double Opt-In) — a data model requiring the customer to confirm their email via an activation link.

• SOI (Single Opt-In) — a data model where the customer joins the database without confirming the email.

• Co-registration — offering the customer another program's offer during sign-up, common in CPL competition campaigns.

• Express withdrawal — a payout made within 48 working hours for a 7% fee, charged on top of other deductions.

Which metrics and KPIs should every affiliate track?

Affiliate metrics turn raw clicks into decisions. CR shows the share of users who convert, CTR the share who click, EPC your average earnings per click, and ROI and ROAS reveal whether paid advertising pays off. Tracking these numbers from the first campaign tells you which offers to scale and which to drop.

• KPI (Key Performance Indicator) — a measure of whether a goal is met; track the right key metrics and analytics tools to monitor it.

• CR (Conversion Rate) — the percentage of users who convert after clicking; if 17 of 100 clickers act, CR is 17%.

• CTR (Click-Through Rate) — the percentage of viewers who click your ad relative to impressions.

• EPC (Earnings Per Click) — your average revenue per click and the ultimate sign of a campaign's success.

• ROI (Return On Investment) — whether your revenue exceeded costs; vital when you run paid ads.

• ROAS (Return On Ad Spend) — ad revenue divided by ad cost, showing how hard each advertising dollar works.

• A/B tests — controlled experiments comparing two versions of content to find the higher-converting variant; see how to run A/B testing.

The core formulas every publisher should recognize:

CR — where A is the number of people who acted and C the number who clicked. Example: 17 ÷ 100 × 100% = 17%.

CTR — where C is the number of clicks and V the number of people who saw the ad.

EPC — where E is total commissions earned and C the number of clicks. Example: $100 ÷ 57 = $1.75.

ROI = (income − costs) ÷ costs × 100%.

ROAS = income ÷ ad costs.

How do affiliate links and tracking tools work?

An affiliate link carries your publisher ID and campaign parameters so the system credits every click and conversion to you. Around it sits the tracking stack: a tracker analyzes performance, postback sends conversion data in real time, and the API exchanges offer data between systems. Together they reveal which sources actually earn.

• Affiliate link — a unique URL with publisher and campaign parameters that records clicks and paid actions, so your commission is assigned correctly.

• Reflink — a referral link with a unique ID that tracks who joined through you; MyLead pays 5% of an invited person's earnings.

• Deep link — a link sending the customer to a specific subpage or product instead of the home page.

• Referral system — MyLead's program that rewards you with 5% of the earnings of users you recommend, at no cost to them.

• Postback — a server-to-server system that sends conversion data to your tracker in real time; learn to use postback in affiliate marketing.

• API (Application Programming Interface) — a mechanism for apps to exchange data, such as pulling the list of MyLead offers; generate your token in the panel.

• Tracker — an analytics tool that monitors campaigns, splits traffic and runs tests; here is how to set up a tracker.

• Auto-redirect — automatic forwarding of a visitor to the advertiser's site; when banned in a program, you cannot use it.

What MyLead tools help you monetize traffic?

MyLead gives publishers tools to earn without owning a product. The flagship is the Content Locker, which blocks a page, file or app until the user completes a task, much like a paywall — but free for the user. Add Smartlinks, HideLink, surveys and Mobile Rewards, and you can monetize almost any traffic you control.

Content Locker comes in four types on MyLead:

• CPA Locker — blocks content on a website or blog until the visitor completes an action.

• Captcha Locker — resembles a reCaptcha bot, but the user completes at least one task from the list to continue.

• File Locker — blocks access to a shared file until the user finishes a task.

• Mobile Rewards — monetizes mobile apps; users earn points for tasks and exchange them for in-app prizes.

Other MyLead tools worth knowing:

• Smartlink — one link that auto-routes users to the best campaign by country or device; discover what a Smartlink is.

• HideLink — MyLead's cloaking system that sends real users to the offer and bots to a safe page, extending a campaign's life on social media; complete a HideLink application.

• Cloaking — showing different content to crawlers and to real users; HideLink is MyLead's built-in cloaking solution.

• Surveys — paid online question forms inside MyLead, a simple extra income source that adds to your balance.

• Pre-lander with offers — a MyLead tool that builds a simple pre-landing page without your own domain or hosting, usable as a widget too.

• Cashback — a platform that refunds part of a purchase; some programs ban affiliate links on cashback sites.

What traffic types and sources are there?

Traffic is simply your website visitors, and a traffic source is where they come from. The key split is organic (free, mostly from search engines) versus paid (ads on search, social and ad networks). Some campaigns restrict incentive or scheme traffic, so matching the allowed source to each offer protects your commissions.

• Traffic — a general term for website visitors, gained organically or through paid activities.

• Traffic source — the platform or activity through which customers find your offer; see how to add a traffic source.

• Organic traffic — free visitors arriving from search engines such as Google, Bing or Yandex; compare free vs paid traffic.

• Paid traffic — visitors from paid ads on search engines, ad networks and social media.

• Incentive traffic — users who agree to take a converting action in exchange for money or another reward.

• Capper traffic — sports-betting traffic built by gathering an audience and sending them match tips.

• Scheme traffic — users acquired with false promises, such as a fake way to beat a casino algorithm.

• Unique user (UU) — a visitor identified by IP or cookies, counting distinct people who reach a page.

• Unique visit — all visits from a single IP, regardless of how many pages were viewed.

• Visit — a single session on a page that can include several views, events or transactions.

• Viral — content designed to spread fast and reach the widest possible audience, often on TikTok.

What ad formats are used in affiliate marketing?

Ad formats are the shapes your promotion takes. Native ads blend into a platform's feed, pop-ups and pop-unders open extra windows, and push notifications mimic short messages. Each campaign lists allowed and banned formats, so reading restrictions before launch keeps your account and your commissions safe.

• Native ad — advertising that matches the look and format of its platform, like a vertical video ad on TikTok.

• Pop-under — a new browser window that opens behind the page and appears after it is closed.

• Pop-up — an ad in a window that pops up over the page; banned in some programs.

• Push — short notifications resembling SMS, usually sent in real time; see push notifications.

• Contextual advertising — ads matched to the viewer's interests, recent searches or data such as location, age and keywords.

• Teaser ad — a two-stage ad: the first stage sparks curiosity, the second delivers the full message.

• Programmatic — fully automated, AI-driven buying and selling of online ads; banned in some programs.

• Retargeting — re-showing ads to people who engaged but did not buy; learn retargeting strategies.

• Toolbar — placing affiliate links in a toolbar at the top of a page; restricted in some programs.

Pop-under — a window revealed after the page is closed.

Pop-up — a window displayed over the page.

Push — notifications sent to a device in real time.

What is GEO and how do Tier countries work?

GEO is the geographic location of your audience, identified by IP, and it defines which country a campaign targets. Countries are grouped into Tiers: Tier 1 holds the most affluent markets with the highest rates, while Tiers 2 and 3 cover developing economies. Matching your traffic's GEO to the offer is decisive for both approval and payout.

Audience and category terms tied to GEO:

• GEO — a specific country a publisher wants to reach or where an offer operates; campaigns list eligible countries.

• Tier — a group of countries ranked by buyers' income; the higher the Tier, the higher your rate. See Tier 1 promotion.

• Target — another word for the target group: everyone you want to reach with your message.

• Target group — the audience your offer is addressed to, defined to maximize profit and cut wasted ad spend.

• Persona — a profile of a typical customer that makes your message easier to match to real people.

• Niche — a market segment with unmet needs and earning potential, such as SPF cosmetics in summer.

• Nutra — short for nutraceuticals: programs promoting health and beauty products like supplements.

• E-commerce — the affiliate category covering online stores; explore e-commerce affiliate programs.

• VOD (Video On Demand) — campaigns tied to on-demand video distribution.

• Sweepstakes — campaigns from the contests and lotteries category.

Country Tiers at a glance — from the highest-paying markets to developing ones:

Tier 1 — countries with the highest affiliate rates.

Tier 2 — countries with average rates.

Tier 3 — countries with the lowest rates.

Which terms cover promotion ethics and account safety?

Affiliate networks reward clean traffic and punish abuse. White hat methods follow the rules, while black hat and fraud break them and trigger blocks. Knowing what counts as a ban, a blocking or a banned method — multi-accounts, rebrokering, brand bidding — protects your account and the money you have already earned.

• White hat — ethical promotion that follows Google's and the network's guidelines to grow visibility safely.

• Black hat — unethical and often banned promotion methods; using them can cost you a ban or a blocking.

• Fraud — leads obtained against the rules, such as fake data or leads from one person; these are never paid and lead to a block.

• Ban — a permanent block of a publisher's account for breaking the network's rules.

• Blocking — a temporary limit on withdrawals, tools or chat after a policy violation; learn how to avoid getting your account blocked.

• Multi-accounts — registering several times on a promoted portal, or running several MyLead accounts; a prohibited practice.

• Rebrokering — reselling offers to other affiliate networks, banned when a program forbids it.

• Brand bidding — bidding on a brand's name in ads; often restricted because the brand's own marketing drove the demand.

• Doorway — a gateway page positioned on popular phrases that forwards traffic elsewhere; a gray/black hat technique.

• Site under — promoting pages with a false or redirecting link.

• Typo — promoting a brand by deliberately misspelling its name; banned in some programs.

Social platforms are strict too — see the common mistakes that get a Facebook ban.

Which technical terms complete the affiliate marketing glossary?

Key takeaways

• Affiliate marketing pays you for results, not impressions — you earn a commission only when a tracked action (sale, lead, install) is completed.

• Settlement models define how you are paid: CPA for actions, CPL for leads, CPS for sales, plus COD, PPI and IVR variants.

• Metrics like CR, CTR, EPC, ROI and ROAS show whether a campaign is profitable; track them from day one.

• MyLead tools — Content Lockers, Smartlinks, HideLink and Mobile Rewards — let you monetize sites, files and apps without your own product.

• GEO and Tier determine rates: Tier 1 countries pay the most, and matching your traffic's GEO to the offer is essential.

• Following white hat rules protects your account; fraud, multi-accounts and banned methods lead to blocks and lost payouts.
