Every few months, a new wave of "affiliate marketing is a scam" content appears online, usually posted by someone who tried a get-rich-quick course and lost money. At the same time, publicly listed companies run entire divisions on affiliate revenue, and European banks, lenders, and investment platforms allocate serious budget to affiliate channels every year. Both things are true at once, and that's exactly why the question deserves a proper answer rather than a hot take.

This article looks at what affiliate marketing actually is, why the scam accusation keeps coming back, and what verifiable data and market structure tell us about Affiliate Marketing Earnings for publishers and about return on investment for the brands that run these programmes. By the end, you'll have a clear framework for telling a legitimate affiliate opportunity apart from a scheme dressed up in affiliate language.

What Is Affiliate Marketing, Really?

Affiliate marketing is a performance-based partnership model where a business pays a publisher, content creator, or comparison site a commission for driving a defined action, such as a sale, a qualified lead, or an approved application. No action, no payment. That single mechanic is what separates it from most of the schemes it gets confused with.

The model has been part of digital commerce since the mid-1990s, and in Europe it runs through established networks rather than informal arrangements. Tradedoubler, founded in Stockholm in 1999, was the first affiliate network to operate across the whole continent and has been listed on Nasdaq Stockholm since 2005, with a network spanning more than 3,000 advertisers and 180,000 publishers worldwide. Awin, built partly on its merger with the German network Zanox, holds a similarly strong position across the UK, Germany, and the wider DACH region.

None of this reads like a scam infrastructure. It reads like an established B2B channel with public reporting obligations, stock exchange oversight, and household-name publishers on the roster.

Why Does Affiliate Marketing Get Called a Scam?

The confusion usually comes from three overlapping sources, and it helps to name them individually rather than lumping affiliate marketing in with all of them.

"Get rich with affiliate marketing" courses. These are sold to individuals, often promising passive income within weeks. The course itself is the product, and the affiliate marketing angle is mostly a hook. This is closer to a course-selling business than to affiliate marketing as brands actually run it.

Pyramid and multi-level schemes wearing affiliate language. Genuine affiliate marketing pays for a customer action taken by someone outside the programme. Pyramid structures pay for recruiting other participants into the scheme. If earnings depend on signing up new "affiliates" rather than on external customer behaviour, that's not affiliate marketing at all, regardless of what the landing page calls it.

Low-quality or fraudulent publishers inside otherwise legitimate programmes. This is the one that actually touches real affiliate programmes, and it's worth taking seriously. Cookie stuffing, fake lead generation, incentivised traffic disguised as organic, and coupon sites that hijack commissions at the last click are documented problems in performance marketing. They don't make the model fraudulent, but they explain why some brands have had a genuinely bad experience and generalised from it.

A common misconception we see among fintech marketing teams evaluating the channel for the first time is treating "affiliate marketing" as a single monolithic activity. In practice it covers everything from a comparison site sending qualified mortgage leads to a finance publisher, through to an influencer posting a discount code. Judging the whole model by its worst publishers is a bit like judging email marketing by spam.

What the Data Actually Says About Affiliate Marketing Earnings

Individual results vary enormously, and any article that gives you a single average income figure for "an affiliate" is oversimplifying a channel with wildly different participant types. A large comparison site with a development team, an established finance blog with years of search authority, and a new Instagram creator are not comparable earners, and treating them as one population produces meaningless averages.

What's more useful is looking at the structure that produces those earnings:

• Established publishers with owned traffic (comparison sites, review platforms, finance content sites) typically earn the most, because they control distribution and can negotiate directly with advertisers or networks.
• Content creators and influencers earn less consistently, since their income depends on audience trust and conversion rates that swing with content performance.
• New entrants often earn very little in the first several months, which is normal for any channel that rewards audience-building and search authority over time, not a sign the model doesn't work.

The publisher side is only half the picture. On the advertiser side, the fact that major publishers such as Condé Nast, Forbes, Hearst, and The Telegraph run affiliate revenue through established networks says something about durability. Media businesses of that scale don't build entire commercial teams around a channel that doesn't produce measurable, repeatable revenue.

For fintech brands specifically, the appeal is the same reason performance marketing exists at all: you pay for outcomes, not impressions. That's a very different risk profile from paid media, where budget can be spent without a single qualified lead to show for it.

How Legitimate Affiliate Programmes Are Structured

If you're trying to judge whether a specific opportunity or programme is real, the commission structure tells you a lot. Fintech affiliate programmes generally use one of three models, and each fits a different type of product.

CPA (cost per action) works well for broad acquisition campaigns with a clear, single conversion point, such as an account opening or a completed sign-up. It's simple to track and simple to explain to publishers, which is part of why it's so widely used for payment providers and digital banking products.

CPL (cost per lead) is the standard for lending, insurance, and brokerage, where the actual transaction happens later and often offline or through a separate sales process. Paying on the lead keeps the model workable even when the final conversion depends on underwriting or advisory steps outside the affiliate's control.

Hybrid (CPL plus CPS) is the model most often used for higher-value products such as P2P lending platforms, investment platforms, and brokers. The publisher receives a CPL upfront, plus a CPS earned on the lead's transaction volume within the first 90 to 180 days after registration, and this is often paired with a fixed fee for content production. This structure rewards publishers for sending genuinely qualified traffic rather than volume for its own sake, because their upside depends on what the lead actually does after signing up.

A useful test for spotting a badly structured or dishonest programme: if the only way to earn meaningfully is to recruit other affiliates, or if commissions are paid regardless of any verifiable customer action, walk away. That's not how CPA, CPL, or hybrid models work, and any programme claiming to be "affiliate marketing" without a real conversion event behind the payout deserves scrutiny.

Red Flags That Separate Scams From Real Opportunities

A few patterns show up consistently in the schemes that give the whole model a bad name.

• Upfront payment required to "join" the affiliate programme or unlock earning tiers
• Earnings tied to recruiting other participants rather than to external customer actions
• No traceable advertiser, product, or brand behind the offer
• Vague or shifting commission terms that change after you've already generated traffic
• Pressure tactics around urgency or scarcity to get people to sign up quickly
• No compliance information, terms of service, or disclosure requirements mentioned anywhere

Real affiliate programmes, by contrast, have a named advertiser, published terms, a tracking mechanism you can verify independently, and payment tied to a specific, auditable action. If a programme can't tell you exactly what triggers a commission, that's the clearest signal something is off.

Compliance Is What Keeps the Channel Legitimate in the EU

One reason affiliate marketing has stayed a credible channel in European financial services is that regulators treat it the same way they treat any other form of marketing communication, not as some grey-area loophole.

Under the Unfair Commercial Practices Directive, undisclosed affiliate relationships are treated as misleading commercial practice, which is why proper affiliate content always discloses the commercial relationship clearly. For investment products, MiFID II requires that marketing communications, including those distributed through affiliates, are fair, clear, and not misleading, with oversight from ESMA and national regulators. Credit and lending promotions fall under the EU Consumer Credit Directive, and any programme promoting crypto-asset products needs to sit within the MiCA framework. Tracking and consent, meanwhile, are governed by GDPR and the ePrivacy rules, which is part of why the shift toward first-party and server-side tracking has accelerated across European affiliate networks in recent years.

A strategic recommendation we give fintech clients: build compliance review into the affiliate recruitment process itself, not as an afterthought once a publisher is already live. Reviewing a publisher's disclosure practices, content standards, and data handling before onboarding costs far less than untangling a compliance issue after a regulator gets involved.

Practical Recommendations for Businesses Evaluating Affiliate Marketing

For a fintech, bank, lender, or investment platform weighing up whether to launch or expand an affiliate programme, a few things consistently separate programmes that perform from ones that quietly underperform.

Start with attribution before you start with commission rates. If you can't accurately track which publisher drove which action, no commission structure will fix that, and you'll end up disputing payouts with your best partners. Choose the commission model to match the sales cycle, not the other way round. Forcing a CPA structure onto a product with a long underwriting process just creates friction and underpaid publishers who eventually leave. Vet publishers on content quality and audience fit, not just traffic volume. A finance comparison site with a smaller, highly relevant audience will often outperform a generic deals site with ten times the reach. And build compliance into onboarding rather than treating it as a separate legal step that happens after the programme launches.

One challenge businesses often encounter is underestimating the ramp-up period. A new affiliate programme rarely produces meaningful volume in the first quarter, because publisher recruitment, content production, and search visibility all take time to build. Programmes judged too early often get cancelled just as they were about to become productive.

Where Circlewise Fits In

Affiliate marketing isn't inherently a scam, and it isn't a guaranteed income stream either. It's a channel, and like any channel, results depend on how well it's structured, who you recruit, and how closely compliance is managed from day one. The data supports the model itself; the scam accusations mostly trace back to a small set of bad actors that never should have been called affiliate marketing in the first place.

For fintech and financial services brands, this is exactly where specialist support pays off. Circlewise works with fintech companies, digital banks, lenders, and investment platforms to design commission structures that match their sales cycle, recruit publishers who actually convert, and keep programmes compliant with EU marketing and disclosure rules from the outset. If you're weighing up affiliate programme management for the first time, or trying to fix an underperforming programme, our team has seen most of the structural mistakes already and can help you avoid repeating them.

Conclusion

The honest answer to "is affiliate marketing a scam" is that the model itself is a legitimate, regulated performance marketing channel used by some of the largest media companies and financial brands in Europe, but it shares a name with a number of unrelated schemes that genuinely are scams. The way to tell them apart is structural: legitimate affiliate marketing pays for verifiable customer actions through CPA, CPL, or hybrid CPL-plus-CPS models, discloses commercial relationships, and operates through traceable networks and named advertisers. Schemes that pay for recruitment, demand upfront fees, or hide who's actually behind the offer aren't affiliate marketing, whatever they call themselves.

If you're a fintech brand evaluating whether to invest in this channel, the practical next step is to look at publisher recruitment quality and commission structure before anything else. Get those right, keep compliance built in from the start, and affiliate marketing performs the way it's designed to: as a cost-efficient, outcome-based acquisition channel rather than a gamble.

Frequently Asked Questions

Is affiliate marketing a legitimate way to earn money? Yes. It's a performance-based marketing model where publishers earn commission for driving verifiable customer actions such as sales or qualified leads. It's used by major media companies and regulated financial brands across Europe, though individual earnings vary widely depending on audience size, niche, and traffic quality.

Why do so many people call affiliate marketing a scam? Most of the scam accusations trace back to unrelated schemes, such as paid courses promising fast passive income, or pyramid structures that pay for recruiting new participants rather than for genuine customer actions. Genuine affiliate marketing pays only when a real, external customer takes a defined action.

How much can affiliate marketers realistically earn? Earnings depend heavily on the publisher type. Established comparison sites and finance publishers with strong search authority tend to earn considerably more than new creators, and new entrants typically earn very little in their first several months while they build audience and trust.

What's the difference between CPA, CPL, and hybrid commission models? CPA pays for a single defined action, such as a completed sign-up, and suits broad acquisition campaigns. CPL pays per qualified lead and is standard for lending, insurance, and brokerage. Hybrid models combine a CPL paid upfront with a CPS earned on the lead's transaction volume over the following 90 to 180 days, and are common for higher-value products like investment platforms and P2P lending.

How can a business tell if an affiliate opportunity is a scam? Look for a named advertiser, published commission terms, a verifiable tracking mechanism, and payment tied to a specific customer action. Red flags include upfront joining fees, earnings based on recruiting other participants, and vague or shifting commission terms.

Is affiliate marketing regulated in the EU? Yes. Affiliate content is subject to the same marketing rules as any other commercial communication. The Unfair Commercial Practices Directive requires disclosure of affiliate relationships, MiFID II governs the marketing of investment products, the EU Consumer Credit Directive covers lending promotions, and GDPR and ePrivacy rules govern tracking and consent.

Do affiliate networks actually pay out reliably? Established European networks operate as publicly accountable businesses with audited financial reporting and long operating histories. That doesn't guarantee every individual advertiser programme runs smoothly, but it does mean the infrastructure behind mainstream affiliate marketing is far more transparent than the schemes that get lumped in with it.

Should fintech companies invest in affiliate marketing? For most fintech products, yes, provided the commission model matches the sales cycle and publisher recruitment focuses on relevant, high-quality audiences rather than raw traffic volume. Performance-based payment structures make it a lower-risk acquisition channel than paid media, but it requires proper performance marketing strategy and compliance oversight to work well.
