Most affiliate marketing guides assume you already speak the language. You open a dashboard, see EPC, postback URLs, and attribution windows, and suddenly you are decoding acronyms instead of running campaigns. This glossary exists to fix that.
Whether you are an affiliate manager launching your first programme, a publisher evaluating offers, or a fintech growth lead trying to understand what your agency is actually reporting, the affiliate definition of every term below is written to be immediately useful. Each entry gives you the meaning, the context, and where the concept fits in a real campaign. No filler, no circular definitions, no jargon explained with more jargon.
The terms are grouped by category so you can jump straight to what matters. Use the alphabetical index at the bottom to find a specific entry fast.
Affiliate marketing basics
Affiliate marketing
Definition: Affiliate marketing is a performance based model where a business pays external partners a commission for generating a specific action, typically a sale, lead, or customer registration.
How it works: The business (advertiser) provides tracking links. Partners (publishers or affiliates) promote the product through their own channels. When a user clicks through and completes the agreed action, the affiliate earns a commission. The advertiser only pays for actual results, which is why the model appeals to budget conscious marketing teams across fintech, e-commerce, and SaaS.

Affiliate
Definition: An affiliate is any individual or business that promotes another company’s products or services in exchange for a commission on resulting actions.
So what does affiliate mean in practice? It could be a finance blogger writing investment platform reviews, a comparison website listing lending products, or a cashback portal redirecting shoppers to retailers. The affiliate definition in marketing always centres on that commercial relationship: promotion in exchange for a performance based payout.
Related terms: Publisher, Affiliate marketer, Affiliate programme
Affiliate marketer
Definition: An affiliate marketer is someone who earns income by promoting third party products or services through affiliate programmes.
This can be a side activity for a content creator or a full time profession. The distinction from “affiliate” is minor in practice. Most industry professionals use the terms interchangeably, though “affiliate marketer” tends to describe individuals rather than companies or websites.
Related terms: Affiliate, Publisher, Affiliate revenue
Affiliate programme
Definition: An affiliate programme is a structured arrangement through which an advertiser recruits, manages, and compensates affiliates for promoting its products or services.
How it works: The programme sets the rules: which actions earn commissions, how much affiliates are paid, what promotional methods are allowed, and how performance is tracked. Some programmes are managed entirely in house. Others run through an affiliate network or partnership platform. A well structured programme also defines compliance guidelines, creative assets, and approval workflows for new publishers.
Related terms: Affiliate network, Affiliate manager, Commission rate
Affiliate partnership
Definition: An affiliate partnership is the commercial relationship between an advertiser and an affiliate, built around shared goals of customer acquisition and revenue generation.
Strong affiliate partnerships go beyond transactional link placements. The best performing ones involve dedicated content, co-branded campaigns, and ongoing communication between the affiliate manager and the publisher. In fintech, these relationships are especially important because financial products require trust, and audiences respond better when the publisher has genuine familiarity with the product.
Related terms: Partnership marketing, Strategic partnership, Partner management
Affiliate link
Definition: An affiliate link is a unique URL assigned to a specific affiliate that tracks clicks and conversions back to that partner.
The link typically contains a publisher identifier and campaign parameters. When a user clicks it, the tracking system logs the click and begins an attribution window. If the user later completes the desired action, the conversion is credited to the affiliate. Misusing or tampering with affiliate links is one of the most common causes of tracking disputes.
Related terms: Tracking link, Deep linking, Conversion tracking
Affiliate commission
Definition: An affiliate commission is the payment an affiliate receives when they generate a qualifying action, such as a sale, a registration, or a qualified lead.
Commissions can be a fixed amount per action, a percentage of the transaction, or a hybrid of both. In European fintech, commissions are often structured as a CPL paid upfront, with a CPS component earned on the lead’s transaction volume over the first 90 to 180 days. Setting the right commission level is one of the most consequential decisions an advertiser makes, because it directly determines which publishers will prioritise your offer over a competitor’s.
Related terms: Commission rate, CPA, CPL, Hybrid commission
Affiliate revenue
Definition: Affiliate revenue is the total income generated through an affiliate programme, either from the advertiser’s perspective (revenue from affiliate driven sales) or the publisher’s perspective (commission earnings).
Related terms: Affiliate performance, ROI, ROAS
Affiliate offer
Definition: An affiliate offer is a specific product, service, or action that an advertiser makes available for affiliates to promote, along with the associated terms, creative assets, and commission structure.
Related terms: Affiliate programme, Advertiser, CPA
Affiliate promotion
Definition: Affiliate promotion covers any marketing activity carried out by an affiliate to drive traffic and conversions for an advertiser’s offer.
This includes blog reviews, social media content, email newsletters, comparison tables, paid advertising (where permitted), and video content. The method matters: under the EU’s Unfair Commercial Practices Directive, affiliate promotions that are not clearly disclosed as commercial content may be treated as misleading.
Related terms: Affiliate content, Affiliate disclosure, Affiliate traffic
Affiliate marketing manager
Definition: An affiliate marketing manager is the person responsible for running an advertiser’s affiliate programme, from partner recruitment and onboarding to performance optimisation and compliance.
Good affiliate managers spend most of their time on relationship management, not dashboards. The difference between a programme that grows steadily and one that stagnates is usually the quality of publisher communication and how quickly the manager activates new partners.
Related terms: Affiliate manager, Partner management, Partner recruitment
Affiliate networks and platforms
Affiliate network
Definition: An affiliate network is an intermediary platform that connects advertisers with publishers, providing the tracking technology, payment processing, and programme management infrastructure both sides need.
How it works: Advertisers list their offers on the network. Publishers browse available programmes, apply, and receive tracking links. The network handles conversion tracking, reporting, and often payment distribution. Working through a network saves time, but advertisers sacrifice some direct control over partner relationships. For brands that want the best of both worlds, a partnership platform can provide network scale alongside direct partner management.
Related terms: Affiliate marketing platform, Publisher marketplace, Advertiser
Affiliate marketing platform
Definition: An affiliate marketing platform is software that enables advertisers to create, manage, and track their own affiliate programmes without relying on a third party network.
Platforms differ from networks in an important way: the advertiser owns the partner relationships directly. The platform provides the technology, tracking, and reporting, but the brand controls recruitment, terms, and payouts. This is the model many European fintech companies prefer because it gives them full visibility into partner quality and compliance.
Related terms: Affiliate marketing software, Affiliate tracking software, Affiliate network
Affiliate marketing software
Definition: Affiliate marketing software is any tool or system used to run affiliate programme operations, including tracking, reporting, commission management, and publisher communication.
Related terms: Affiliate marketing platform, Affiliate tracking software, Affiliate management software
Affiliate tracking software
Definition: Affiliate tracking software records clicks, conversions, and attributions across affiliate campaigns, giving advertisers and publishers a shared source of truth for performance data.
Reliable tracking is the backbone of every affiliate programme. If the tracking breaks, commissions go unrecorded, publishers lose trust, and the programme deteriorates. This is why most experienced affiliate managers test tracking integrations thoroughly before launching any new offer.
Related terms: Conversion tracking, Server-to-server tracking, Postback
Affiliate management software
Definition: Affiliate management software combines tracking with partner administration tools, handling everything from publisher applications and approvals to payment scheduling and compliance monitoring.
Related terms: Affiliate marketing platform, Affiliate manager, Partner management
Partnership platform
Definition: A partnership platform is a technology solution that manages all types of performance partnerships, including affiliates, referral partners, influencers, and strategic business partners, in a single system.
Partnership platforms have evolved beyond traditional affiliate networks. They support multiple partner types, flexible commission structures, and advanced attribution. For companies managing relationships across several markets, having everything in one place reduces complexity.
Related terms: Partnership marketing, Affiliate marketing platform, Partner relationship management
Publisher marketplace
Definition: A publisher marketplace is a directory within a network or platform where advertisers can discover, evaluate, and recruit publishers for their affiliate programmes.
Related terms: Affiliate network, Publisher, Partner recruitment
Advertiser
Definition: An advertiser is the business that creates an affiliate programme and pays commissions to affiliates for generating specified actions.
In affiliate marketing terminology, the advertiser is sometimes called the merchant or brand. They set the programme terms, provide creative assets, and define which conversions qualify for commission.
Related terms: Merchant, Affiliate programme, Publisher
Publisher
Definition: A publisher is any individual or business that promotes an advertiser’s products through their own marketing channels in exchange for affiliate commissions.
Publishers come in many forms: content sites, comparison platforms, finance bloggers, influencers, email marketers, cashback portals, and coupon aggregators. The quality and relevance of a publisher’s audience matters far more than their raw traffic numbers.
Related terms: Affiliate, Content affiliate, Finance publisher
Merchant
Definition: Merchant is another term for the advertiser or brand whose products or services are being promoted through an affiliate programme.
Related terms: Advertiser, Affiliate programme
Affiliate manager
Definition: An affiliate manager is the person within an advertiser’s organisation or network who is responsible for the day to day running and growth of the affiliate programme.
Related terms: Affiliate marketing manager, Network manager, Partner management
Network manager
Definition: A network manager is a professional employed by an affiliate network who oversees advertiser and publisher accounts, mediates disputes, and helps optimise programme performance.

Affiliate commission and pricing models
| Model | What the advertiser pays for |
| CPA | A completed acquisition (registration, purchase, deposit) |
| CPL | A qualified lead (form submission, sign-up) |
| CPS | A confirmed sale or transaction |
| CPC | Each click on the affiliate link |
| CPM | Every 1,000 impressions of the ad |
| Hybrid (CPL + CPS) | An upfront CPL plus CPS on subsequent transaction volume |
CPA (cost per acquisition)
Definition: CPA is a commission model where the advertiser pays a fixed fee each time an affiliate generates a defined acquisition, such as a completed registration, a funded account, or a first purchase.
CPA is the most common model in European affiliate marketing because it aligns incentives cleanly: publishers earn when they deliver real customers, and advertisers pay nothing for clicks or impressions that go nowhere. The challenge is setting the right CPA level. Too low, and quality publishers will not bother. Too high, and you attract low quality traffic that converts but never retains. For a detailed breakdown of how CPA works in practice, see the cost per acquisition guide.
Related terms: CPL, CPS, Hybrid commission, Commission rate
CPL (cost per lead)
Definition: CPL is a pricing model where the advertiser pays a fixed amount for each qualified lead an affiliate generates, typically defined as a completed registration form, an application submission, or a verified sign-up.
CPL works well for products where the sale takes time to close, such as lending, insurance, and brokerage. The advertiser acquires the lead at a predictable cost and nurtures the conversion internally.
Related terms: CPA, Hybrid commission, Conversion
CPS (cost per sale)
Definition: CPS is a commission model where the affiliate earns a payment only when a confirmed sale or financial transaction occurs.
Related terms: CPA, Commission rate, Affiliate commission
CPC (cost per click)
Definition: CPC is a pricing model where the advertiser pays a set fee each time someone clicks an affiliate link, regardless of whether that click leads to a conversion.
CPC is relatively uncommon in affiliate marketing because it shifts risk to the advertiser. Most advertisers prefer CPA or CPL, where payment is tied to a concrete outcome.
Related terms: CPM, Click-through rate, Affiliate tracking
CPM (cost per mille)
Definition: CPM is the cost an advertiser pays per 1,000 ad impressions, used primarily in display advertising and brand awareness campaigns rather than performance affiliate programmes.
Related terms: CPC, Affiliate promotion
Hybrid commission
Definition: A hybrid commission structure combines two pricing models, most commonly a CPL paid upfront plus a CPS earned on the lead’s transaction volume in the first 90 to 180 days after registration.
In fintech affiliate marketing, hybrid models are the standard for high value products like P2P lending platforms, investment platforms, and brokers. The upfront CPL compensates the publisher for the effort of producing quality content and driving registrations. The CPS component rewards them for the lead quality, since they earn more when their referred users actually invest or transact. Many hybrid arrangements also include a fixed fee for content production.
Related terms: CPL, CPS, Commission rate, Affiliate commission
Recurring commission
Definition: A recurring commission pays the affiliate each time the referred customer renews, subscribes, or makes a repeat transaction, usually for a defined period or as long as the customer remains active.
SaaS companies and subscription based financial services sometimes use recurring commissions to attract publishers who produce evergreen content.
Related terms: CPS, Customer lifetime value, Commission rate
Flat fee
Definition: A flat fee is a one-time, fixed payment to an affiliate for a specific deliverable, such as a product review, sponsored article, or promotional placement, independent of performance results.
Related terms: CPA, Content affiliate, Affiliate promotion
Tiered commission
Definition: A tiered commission structure increases the affiliate’s payout rate as they hit higher performance thresholds, rewarding volume and consistency.
For example, an advertiser might pay EUR 30 per lead for the first 50 conversions per month, then EUR 40 per lead for anything above that. Tiers motivate top publishers to prioritise your programme and are a useful tool for building loyalty among your best partners.
Related terms: Commission rate, Affiliate performance, CPA
Commission rate
Definition: The commission rate is the specific amount or percentage an advertiser pays per qualifying action within an affiliate programme.
Setting commission rates is part art, part arithmetic. You need to cover the publisher’s effort, compete with alternative offers in your vertical, and still keep your customer acquisition cost within margin. Reviewing what competitors offer through the same networks is a practical starting point.
Related terms: CPA, CPL, Affiliate commission
Affiliate tracking and attribution
Affiliate tracking
Definition: Affiliate tracking is the technical process of recording clicks, conversions, and other interactions generated by affiliates so that each action can be attributed to the correct partner and commission paid accordingly.
Tracking is where affiliate marketing lives or dies. Without accurate tracking, commissions are miscounted, publisher trust erodes, and programme growth stalls. Modern tracking uses a combination of cookies, server-to-server postbacks, and pixel fires. With tightening privacy regulations under GDPR and the ePrivacy Directive, server side tracking has become the more reliable method across the EU.
Related terms: Conversion tracking, Server-to-server tracking, Cookie window
Conversion tracking
Definition: Conversion tracking is the measurement of specific user actions, such as a purchase, sign-up, or deposit, that determine whether an affiliate earns a commission.
Related terms: Affiliate tracking, Conversion, Tracking pixel
Conversion
Definition: A conversion is the completion of a desired action by a user who arrived through an affiliate link, such as making a purchase, submitting a lead form, or funding an account.
What counts as a conversion varies by programme. Some advertisers define it broadly (any registration). Others require a qualified action (a funded account with a minimum deposit). Defining conversions clearly in your programme terms prevents disputes later.
Related terms: Conversion rate, CPA, Attribution
Attribution
Definition: Attribution is the process of determining which affiliate or marketing touchpoint receives credit for a conversion.
Attribution models directly affect which publishers get paid and how much. The model you choose shapes publisher behaviour: last click attribution rewards closers, first click attribution rewards introducers, and multi-touch models attempt to distribute credit fairly across the journey.
Related terms: First-click attribution, Last-click attribution, Multi-touch attribution, Attribution window
Attribution window
Definition: An attribution window is the period of time after a user clicks an affiliate link during which any resulting conversion is still credited to that affiliate.
Windows typically range from 24 hours to 90 days, depending on the product’s purchase cycle. Financial products usually require longer windows because users research and compare before committing. Setting a window that is too short punishes publishers whose content drives early stage consideration.
Related terms: Cookie window, Attribution, Conversion tracking
Cookie window
Definition: A cookie window is the duration for which a tracking cookie remains active on a user’s browser after they click an affiliate link.
Cookie windows and attribution windows often overlap, but they are not always identical. Browser level restrictions (third party cookie blocking in Safari and Firefox, evolving Chrome policies) have reduced cookie reliability, pushing the industry toward server-to-server tracking.
Related terms: Attribution window, Affiliate tracking, Cross-device tracking
Tracking link
Definition: A tracking link is a URL that contains parameters identifying the affiliate, campaign, and sometimes the specific creative or placement, so clicks and conversions can be attributed correctly.
Related terms: Affiliate link, Deep linking, Affiliate tracking
Tracking pixel
Definition: A tracking pixel is a small piece of code placed on a confirmation page (such as a “thank you” or “registration complete” page) that fires when a conversion occurs, notifying the tracking system.
Related terms: Conversion tracking, Postback, Affiliate tracking
First-click attribution
Definition: First-click attribution gives full credit for a conversion to the affiliate whose link the user clicked first, regardless of any subsequent interactions with other affiliates.
Related terms: Last-click attribution, Multi-touch attribution, Attribution
Last-click attribution
Definition: Last-click attribution assigns all conversion credit to the final affiliate link the user clicked before completing the action.
Last-click is still the default in most affiliate programmes. It is simple to implement and easy for publishers to understand. But it systematically undervalues content publishers who introduce users to a product early in the research phase, only for a coupon or cashback site to capture the final click.
Related terms: First-click attribution, Multi-touch attribution, Attribution
Multi-touch attribution
Definition: Multi-touch attribution distributes conversion credit across multiple touchpoints in the customer journey, rather than assigning it entirely to the first or last interaction.
This model is more accurate for complex purchase journeys, especially in financial services where a user might read a review, visit a comparison site, and then return directly before converting. The challenge is practical: multi-touch attribution requires robust cross-channel tracking and clear rules for how credit is split.
Related terms: First-click attribution, Last-click attribution, Attribution, Conversion path attribution
Cross-device tracking
Definition: Cross-device tracking identifies and connects a single user’s activity across multiple devices, such as researching on a mobile phone and converting on a desktop.
Without cross-device tracking, conversions that start on one device and finish on another appear as new, unattributed sessions. This is a significant blind spot in affiliate marketing, particularly for financial products where users frequently switch between devices during their research.
Related terms: Affiliate tracking, Server-to-server tracking, Attribution
Deep linking
Definition: Deep linking sends a user to a specific page within an advertiser’s website, rather than the homepage, through an affiliate link.
Deep links dramatically improve conversion rates. Sending a user who clicked on a review of a specific investment product directly to that product’s landing page is far more effective than dropping them on a generic homepage and hoping they navigate.
Related terms: Affiliate link, Tracking link, Conversion rate
Postback
Definition: A postback is a server-to-server notification sent from the advertiser’s tracking system to the affiliate network or publisher when a conversion occurs.
Related terms: Server-to-server tracking, Conversion tracking, Tracking pixel
Server-to-server tracking
Definition: Server-to-server (S2S) tracking records conversions through direct communication between the advertiser’s server and the tracking platform, bypassing the user’s browser entirely.
S2S tracking has become the gold standard in affiliate marketing, largely because it is unaffected by cookie blocking, ad blockers, and browser privacy restrictions. If you are running a programme in the EU where GDPR consent requirements already complicate cookie based tracking, server side solutions are the pragmatic choice.
Related terms: Postback, Affiliate tracking, Cookie window
Referral tracking
Definition: Referral tracking monitors and attributes user actions that originate from a referral link or code, often used in referral programmes alongside or instead of traditional affiliate tracking.
Related terms: Affiliate tracking, Referral partner, Tracking link
Affiliate performance and analytics
Conversion rate
Definition: Conversion rate is the percentage of users who complete the desired action out of the total number who clicked an affiliate link.
A programme’s conversion rate tells you more about landing page quality and offer fit than about publisher performance. If conversion rates are low across all publishers, the problem is almost always on the advertiser’s side: the landing page, the sign-up flow, or the offer itself.
Related terms: Click-through rate, EPC, Affiliate performance
Click-through rate (CTR)
Definition: CTR is the percentage of users who click an affiliate link out of the total number who were exposed to it.
Related terms: Conversion rate, CPC, Affiliate tracking
EPC (earnings per click)
Definition: EPC is the average commission earned per click on an affiliate link, calculated by dividing total commissions by total clicks over a given period.
Publishers use EPC as a shorthand for comparing how profitable different programmes are. An offer with a high CPA but low conversion rate might have the same EPC as an offer with a lower CPA but better converting landing page. EPC cuts through the noise.
Related terms: Conversion rate, Commission rate, Affiliate revenue
ROI (return on investment)
Definition: ROI measures the profitability of affiliate marketing spend by comparing the revenue generated against the total cost, including commissions, platform fees, and management time.
Related terms: ROAS, Customer acquisition cost, Affiliate performance
ROAS (return on ad spend)
Definition: ROAS calculates how much revenue is generated for each unit of marketing spend, expressed as a ratio or multiple.
Related terms: ROI, Affiliate revenue, CPA
Customer acquisition cost (CAC)
Definition: CAC is the total cost of acquiring one new customer, factoring in all marketing and operational expenses, not just the affiliate commission.
Many affiliate managers make the mistake of looking only at the CPA they pay publishers and calling it their acquisition cost. True CAC includes platform fees, management labour, creative production, and any bonus incentives. Understanding your full CAC helps you set sustainable commission rates.
Related terms: CPA, Customer lifetime value, ROI
Customer lifetime value (CLV or LTV)
Definition: CLV is the total revenue a business expects from a single customer over the entire duration of their relationship.
CLV is the number that makes or breaks commission generosity. If your average customer generates EUR 500 in revenue over two years, you can afford a significantly higher commission than if they churn after a month. In European fintech, where platforms compete for investors who may allocate capital across several services, calculating CLV accurately is complex but essential.
Related terms: Customer acquisition cost, Recurring commission, Affiliate revenue
Average order value (AOV)
Definition: AOV is the average monetary value of each transaction completed through an affiliate referral.
Related terms: Conversion rate, CPS, Affiliate revenue
Incrementality
Definition: Incrementality measures whether the conversions generated through an affiliate programme are genuinely new, or whether those customers would have converted anyway without affiliate involvement.
This is one of the trickiest questions in affiliate marketing. A coupon site claiming credit for a user who was already on the checkout page is not incremental. A finance blogger introducing someone to a platform they had never heard of is. Measuring incrementality usually requires controlled testing and holdout groups, which most programmes do not bother with. Those that do often discover a significant portion of their “affiliate” conversions are not truly incremental.
Related terms: Attribution, Multi-touch attribution, Affiliate performance
Affiliate performance
Definition: Affiliate performance is the overall effectiveness of an affiliate programme or individual affiliate, measured by KPIs such as conversions, revenue, conversion rate, EPC, and return on investment.
For a deeper look at which metrics matter and how to measure them, see the guide on how to measure affiliate marketing performance.
Related terms: Affiliate KPI, Affiliate reporting, EPC
Affiliate KPI
Definition: An affiliate KPI is a key performance indicator used to evaluate the success of an affiliate programme or individual affiliate against business objectives.
Common KPIs include conversion rate, EPC, number of active publishers, revenue per publisher, and new customer acquisition volume. The right KPIs depend on your programme’s maturity. Early stage programmes should focus on publisher activation and first conversions. Mature programmes shift toward incrementality and lifetime value.
Related terms: Affiliate performance, Affiliate reporting, Conversion rate
Affiliate reporting
Definition: Affiliate reporting is the process of collecting, analysing, and presenting performance data from affiliate campaigns and publisher activity.
Related terms: Affiliate dashboard, Affiliate KPI, Affiliate performance
Affiliate dashboard
Definition: An affiliate dashboard is the interface where advertisers and publishers view real time performance data, including clicks, conversions, commissions, and campaign metrics.
Related terms: Affiliate reporting, Affiliate marketing platform
Partner management
Partnership marketing
Definition: Partnership marketing is a broader strategy where two or more businesses collaborate to achieve mutual growth, encompassing affiliate marketing, referral programmes, co-marketing, technology integrations, and strategic alliances.
Partnership marketing goes beyond the transactional “link and commission” model of traditional affiliate marketing. It involves deeper collaboration, shared objectives, and often custom commercial arrangements. European fintech companies increasingly treat partnership marketing as a core growth channel rather than a subset of digital advertising. Circlewise’s Partnership Hub is built around this approach, giving brands the tools to manage all partnership types in one place.
Related terms: Affiliate marketing, Strategic partnership, Partner programme
Partner marketing
Definition: Partner marketing is an umbrella term for any marketing activity conducted through or with partners, including affiliates, referral partners, technology partners, and co-marketing partners.
Related terms: Partnership marketing, Affiliate marketing, Channel partner
Partner programme
Definition: A partner programme is an organised framework for recruiting, managing, and rewarding partners who contribute to a business’s growth objectives.
Related terms: Affiliate programme, Partnership marketing, Partner management
Partner management
Definition: Partner management covers the operational processes of recruiting, onboarding, activating, and maintaining relationships with performance partners.
Related terms: Partner onboarding, Partner activation, Affiliate manager
Partner recruitment
Definition: Partner recruitment is the process of identifying, vetting, and enrolling new affiliates or partners into a programme.
Recruitment is where most programmes underperform. Many advertisers set up a programme and wait for publishers to find them. Proactive outreach to relevant content creators, comparison sites, and niche publishers in your vertical consistently produces better results than passive listings.
Related terms: Partner onboarding, Publisher marketplace, Affiliate manager
Partner onboarding
Definition: Partner onboarding is the process of equipping new partners with the tools, information, and access they need to start promoting effectively.
Good onboarding reduces the time between a publisher joining your programme and generating their first conversion. This means providing clear programme terms, pre-built creative assets, product information, and a responsive point of contact. Publishers who feel supported during onboarding become active faster and stay longer.
Related terms: Partner activation, Partner enablement, Partner management
Partner activation
Definition: Partner activation refers to the efforts taken to move onboarded partners from passive status to actively generating traffic and conversions.
Many programmes have a large pool of signed-up publishers who never send a single click. Activation campaigns, personalised outreach, exclusive offers, and co-created content are all tactics that move partners from registered to productive.
Related terms: Partner onboarding, Partner enablement, Affiliate performance
Partner enablement
Definition: Partner enablement is the ongoing provision of resources, training, and support that helps partners promote products more effectively.
Related terms: Partner activation, Partner management, Affiliate content
Partner relationship management (PRM)
Definition: PRM is the practice and technology of managing ongoing partner relationships, covering communication, performance tracking, dispute resolution, and strategic planning.
Related terms: Partner management, Partnership platform, Affiliate management software
Strategic partnership
Definition: A strategic partnership is a long term, high value collaboration between two businesses that goes beyond standard affiliate arrangements, often involving joint product development, co-investment, or exclusive market access.
Related terms: Partnership marketing, Affiliate partnership, Technology partner
Referral partner
Definition: A referral partner is a person or business that refers potential customers directly, often through a unique referral link or code, in exchange for a reward or commission.
Related terms: Referral tracking, Affiliate, Partner programme
Technology partner
Definition: A technology partner is a company whose product or service integrates with another business’s offering, and which may refer or co-market to shared audiences as part of a partnership arrangement.
Related terms: Strategic partnership, Channel partner, Partnership marketing
Channel partner
Definition: A channel partner is a business that markets and sometimes sells another company’s products through their own distribution channel, earning commissions or margins on resulting business.
Related terms: Partner marketing, Referral partner, Strategic partnership
Publisher and promotion types
Content affiliate
Definition: A content affiliate promotes products through editorial content such as blog articles, reviews, guides, videos, or podcasts, typically by embedding affiliate links within genuinely useful material.
Content affiliates are often the most valuable partners in a programme because their recommendations carry editorial weight. In fintech, where trust determines conversion, a thorough product review from a credible finance publisher converts far better than a banner ad.
Related terms: Finance publisher, Affiliate content, Influencer affiliate
Coupon affiliate
Definition: A coupon affiliate promotes products primarily through discount codes, vouchers, or cashback incentives, attracting deal seeking consumers.
Coupon affiliates drive volume, but advertisers should monitor their impact on margins and incrementality. A user who was already about to purchase, then Googles for a discount code, is not the same as a user who discovered the product through the coupon site. Set clear rules about when and where coupon codes can be promoted.
Related terms: Incentivised traffic, Affiliate promotion, Incrementality
Comparison website
Definition: A comparison website presents multiple products or services side by side, allowing users to evaluate features, pricing, and reviews before making a decision.
In financial services, comparison sites are major traffic drivers. They perform well because they match the user’s intent: someone comparing investment platforms or lending products is already close to a decision.
Related terms: Content affiliate, Finance publisher, Conversion rate
Finance publisher
Definition: A finance publisher is a content creator or media company specialising in financial topics, such as investing, personal finance, lending, or insurance, who promotes financial products through affiliate partnerships.
Finance publishers are the backbone of fintech affiliate marketing programmes. Their audiences tend to be educated, high intent, and willing to act on well-supported recommendations.
Related terms: Content affiliate, Comparison website, Influencer affiliate
Influencer affiliate
Definition: An influencer affiliate promotes products to their social media or content audience through affiliate links, earning commissions based on the actions their followers take.
Related terms: Influencer marketing, Content affiliate, Affiliate promotion
Influencer marketing
Definition: Influencer marketing is a strategy where brands partner with individuals who have established audiences and credibility to promote products through their personal channels.
When combined with affiliate tracking, influencer marketing shifts from a brand awareness exercise to a measurable performance channel. The influencer earns based on results, and the advertiser gains full visibility into what each partnership delivers.
Related terms: Influencer affiliate, Affiliate partnership, Content affiliate
Affiliate content
Definition: Affiliate content is any editorial or promotional material created by an affiliate to drive traffic toward an advertiser’s offer.
Related terms: Affiliate promotion, Content affiliate, Affiliate disclosure
Affiliate website
Definition: An affiliate website is a site built primarily to earn affiliate commissions by publishing content that drives users to advertiser offers.
Related terms: Content affiliate, Affiliate traffic, Comparison website
Affiliate disclosure
Definition: An affiliate disclosure is a statement informing users that the content they are reading contains commercial affiliate links and that the publisher may earn a commission from resulting actions.
Disclosures are not optional. Under the EU’s Unfair Commercial Practices Directive, undisclosed commercial content is treated as a misleading commercial practice. GDPR also requires transparency about how tracking data is collected and used. Clear, prominent disclosures protect both the publisher and the advertiser.
Related terms: Compliance, GDPR, Affiliate content
Affiliate traffic
Definition: Affiliate traffic is the website visitors or users generated through affiliate marketing activities.
Related terms: Organic traffic, Paid traffic, Incentivised traffic
Organic traffic
Definition: Organic traffic refers to visitors who arrive at a website through unpaid search engine results, as opposed to paid advertising or direct referrals.
Related terms: Affiliate traffic, Paid traffic, SEO
Paid traffic
Definition: Paid traffic consists of visitors acquired through paid advertising channels, such as search ads, social media ads, or display campaigns, sometimes used by affiliates to promote advertiser offers.
Related terms: Affiliate traffic, Organic traffic, CPC
Incentivised traffic
Definition: Incentivised traffic comes from users who are offered a reward (cashback, points, discounts) for completing an action through an affiliate link.
Incentivised traffic can generate volume quickly, but user quality tends to be lower. In fintech, where the advertiser needs funded accounts and active investors, incentivised users who sign up for the reward and never deposit capital waste the commission budget. Most fintech programmes either cap or exclude incentivised traffic for this reason.
Related terms: Coupon affiliate, Traffic quality, Affiliate promotion
Compliance, quality, and fraud
Affiliate fraud
Definition: Affiliate fraud is any deliberate attempt to generate illegitimate commissions through deceptive practices, such as fake clicks, fabricated leads, or manipulated attribution.
Fraud is an ongoing operational concern, not something you solve once and forget. Common tactics include bot traffic, click injection on mobile, cookie stuffing, and form filling with fabricated data. Sophisticated fraud looks like real traffic in aggregate but falls apart when you examine individual user behaviour. Ongoing monitoring, clear programme terms, and quick enforcement are the best defences.
Related terms: Click fraud, Cookie stuffing, Invalid traffic, Traffic quality
Click fraud
Definition: Click fraud is the practice of artificially inflating click counts on affiliate links through bots, scripts, or coordinated human activity to generate unearned commissions under CPC models.
Related terms: Affiliate fraud, Invalid traffic, CPC
Invalid traffic (IVT)
Definition: Invalid traffic is any traffic that does not come from a genuine user with real intent, including bot traffic, accidental clicks, and traffic generated through fraudulent methods.
Related terms: Affiliate fraud, Traffic quality, Click fraud
Compliance
Definition: Compliance in affiliate marketing refers to adherence to legal regulations, industry standards, and programme terms governing how products are promoted and how data is collected and used.
In the EU, compliance covers several overlapping frameworks. MiFID II governs how investment products are marketed (promotions must be fair, clear, and not misleading). The EU Consumer Credit Directive applies to lending and credit advertising. MiCA covers crypto-asset promotions. And GDPR, together with the ePrivacy rules, governs tracking, cookies, and consent. Getting compliance wrong can result in regulatory action against the advertiser, not just the affiliate.
Related terms: Affiliate disclosure, GDPR, Brand bidding
Brand bidding
Definition: Brand bidding occurs when an affiliate bids on an advertiser’s brand name or trademarked terms in paid search advertising, effectively competing with the brand for its own search traffic.
Most programmes prohibit brand bidding because it cannibalises organic and direct traffic the advertiser would have received for free. If you allow it, set strict rules about ad copy, landing page requirements, and approved search terms.
Related terms: Trademark bidding, Compliance, Paid traffic
Trademark bidding
Definition: Trademark bidding is a specific type of brand bidding where an affiliate uses the advertiser’s registered trademarks as paid search keywords.
Related terms: Brand bidding, Compliance
Cookie stuffing
Definition: Cookie stuffing is a fraudulent technique where an affiliate drops tracking cookies on a user’s browser without their knowledge, claiming credit for conversions the affiliate played no role in generating.
Related terms: Affiliate fraud, Cookie window, Compliance
Traffic quality
Definition: Traffic quality assesses how genuine, relevant, and likely to convert the visitors generated by an affiliate are.
High quality traffic comes from users who match the advertiser’s target audience and have genuine intent. Low quality traffic, whether from irrelevant sources, incentivised users, or fraudulent methods, inflates metrics without delivering business value.

Frequently asked questions
What is affiliate marketing in simple terms?
Affiliate marketing is a performance based arrangement where a business pays external partners (affiliates) a commission for generating specific results, such as sales, registrations, or leads. The affiliate promotes the product through their own channels and earns a payout only when a measurable action occurs. The model removes upfront advertising risk for the business because payment is tied directly to outcomes.
What does affiliate mean?
An affiliate is a person or company that promotes another business’s products or services in exchange for a commission. The affiliate definition in marketing specifically refers to partners who drive actions through tracked links, earning a fee when their referral leads to a conversion.
What is an affiliate network?
An affiliate network is a platform that connects advertisers with publishers, providing the tracking, reporting, and payment infrastructure both sides need. The network acts as an intermediary, making it easier for advertisers to find suitable partners and for publishers to access multiple programmes through a single account.
What is an affiliate programme?
An affiliate programme is the structured framework through which a business recruits, manages, and compensates affiliates. It defines commission rates, permitted promotional methods, tracking mechanisms, and payout terms. Programmes can run through networks, through standalone platforms, or as hybrid setups.
How do affiliate commissions work?
The advertiser defines a qualifying action (such as a sale or lead) and a commission amount. When an affiliate generates that action through their tracked link, the system records the conversion and credits the commission. Payments are typically processed monthly. Common models include CPA (fixed fee per acquisition), CPL (fee per lead), and hybrid structures that combine an upfront CPL with a CPS component tied to subsequent transaction volume.
What is CPA in affiliate marketing?
CPA stands for cost per acquisition. It is the most widely used commission model in affiliate marketing, particularly in European fintech. The advertiser pays a fixed amount each time an affiliate generates a defined acquisition, such as a funded account, a completed purchase, or a qualified registration.
What is affiliate tracking?
Affiliate tracking is the technology that records clicks, conversions, and user interactions across affiliate campaigns, attributing each action to the correct publisher. It uses a combination of tracking links, cookies, pixels, and server-to-server postbacks. Accurate tracking is the foundation of any functional affiliate programme.
What is the difference between affiliate marketing and partnership marketing?
Affiliate marketing is one component of partnership marketing. It focuses specifically on performance based relationships where partners earn commissions for driving measurable actions. Partnership marketing is broader, encompassing affiliates, referral partners, strategic alliances, technology integrations, and co-marketing arrangements. Many businesses start with affiliate marketing and expand into a full partnership marketing strategy as their programme matures.
