Affiliate Marketing Is 25 Years Old: Why the Model Hasn't Changed
US advertisers spend 12,42 billion dollars on it, yet the mechanics date back to 1996. Where affiliate marketing truly falls short, and what is taking over.
Key takeaways
- US advertisers invested 12,42 billion dollars in affiliate marketing in 2025, a market that remains reserved for professional publishers.
- The creator economy is worth 250 billion dollars and is heading toward 480 billion in 2027: the most measurable model is also the smallest.
- Affiliate marketing relies on the third-party cookie, and therefore on attribution that no longer measures WhatsApp shares or private conversations.
- A satisfied customer has no access to their favorite brand's affiliate program: the system was designed for media outlets, not people.
- Opening up the mechanics to everyone changes the order of magnitude: from a network of a few thousand publishers to your customer base and their circles.
Affiliate marketing was a simple promise: pay the media outlets that bring you customers.
It could hardly be healthier. No budget committed blindly, compensation strictly tied to results. When Amazon launched its Associates program in 1996, it was the first time an advertiser could buy performance and nothing else.
Twenty-five years later, the mechanics haven’t moved an inch. The tracked link, the cookie, the commission, the monthly bank transfer: it is the exact same setup. Meanwhile, the way people recommend products to each other has changed three times over.
How Much Is the Affiliate Marketing Market Really Worth?
Let’s review the mechanics, because everything else stems from them. A publisher (website, blog, comparison site, creator) places a tracked link to a merchant. A user clicks, buys, and the publisher earns a commission. A cookie dropped on click connects the two moments.
In terms of volume, US advertisers dedicated 12,42 billion dollars in 2025, and this is expected to reach 13,81 billion in 2026, an 11,3 % growth (eMarketer). The channel is also estimated to influence 241 billion dollars in US e-commerce sales over the year.
Globally, estimates vary depending on what you choose to count: the affiliate marketing platform market alone is valued at 22,6 billion dollars in 2025 (Grand View Research). Focus on the range rather than the decimal: no one agrees on the scope, which already says a lot about the sector’s maturity.
Now, the comparison that hurts. The creator economy is worth 250 billion dollars, with a projection of 480 billion in 2027 (Goldman Sachs Research).
The oldest model in digital marketing is also the only one paid strictly per sale. And it is, by far, the smallest. There is a reason for that.
Why hasn’t the model moved since 1996?
Four points of friction, accumulated over a quarter of a century. None is an accident: each stems from an assumption that was correct in 1996 and no longer is.
A closed door. Affiliate marketing is reserved for professionals. You need a website, an audience, an application, often manual approval. A customer who loves your brand and tells fifteen people about it has no access, no matter how many sales she generates. The system was designed for media outlets, back when only media could drive traffic. That assumption has been false for fifteen years.
Volume at all costs. The industry’s reflex has long been to pile up affiliates. Thousands of passive partners, zero transparency on the value actually created, and reliance on intermediary platforms taking a cut along the way. The result: an indistinguishable mix of partners who generate demand and actors who simply capture last-touch attribution when the buyer had already made up their mind.
Payouts that arrive too late. Deferred commissions, payout thresholds, monthly or sometimes quarterly transfers. That is manageable for a full-time publisher. It makes no sense for someone who simply sent a link to their sister.
No relationship. The affiliate doesn’t know the brand. The brand doesn’t know the affiliate. Neither knows the buyer. A transaction between three strangers, from which no one walks away with actionable data.
Does last-click attribution still hold up?
No, and this is the most urgent problem of all, because it undermines the model’s technical foundation.
Everything relies on the third-party cookie. With browser protections, cross-device fragmentation, and ITP limitations on cookie lifespan, last click has become an accounting convention rather than a measurement. We continue to pay out based on a signal that no longer reflects the actual journey.
What completely escapes the system is where people actually recommend products. Direct traffic accounts for roughly 37 % of visitors to a website, and a link shared on WhatsApp, Slack, Discord, or via direct message on Instagram arrives without a referrer, every single time. The mechanism is detailed in Dark Social: Why Your Word-of-Mouth Is Invisible in Analytics.
In other words, affiliate marketing accurately measures the channel that matters least and fails to see the one that matters most. A coupon site captures a commission on a buyer who was going to purchase anyway; the person who actually triggered the decision, three days earlier in a private conversation, does not exist on any dashboard.
What I took away from Affiliate Summit West
I should clarify right away that what follows is my personal take on the event, not an official industry statement. But walking out of the latest Affiliate Summit West, the thought in my mind was simple.
Affiliate marketing, as we know it, is dead.
Not because it no longer works. Because it is no longer aligned with how people influence each other.
Three things struck me in hallway conversations, far more than on stage.
Affiliate marketing is ceasing to be a channel and becoming a system. AI, post-cookie attribution, automation: performance no longer relies on links dropped into articles, but on recommendation mechanics and tracking that work without cookies.
The future of affiliate marketing belongs to individuals. Creators, customers, communities: those who recommend are finally starting to be recognized as full-fledged business entry points. And they want three very practical things: to understand what they earn, to get paid quickly, and to stay in control of their relationship.
The ‘volume at all costs’ model is over. No one defends it in public anymore. How could anyone believe in it for so long?
What affiliate marketing looks like when it opens to everyone
The logical next step takes the 1996 promise and applies it to the right people.
| Criterion | Traditional affiliate marketing | Open affiliate marketing |
|---|---|---|
| Access | Vetted professional publishers | Any customer, in two clicks |
| Attribution | Third-party cookie, last click | Native tracking, cookieless |
| Payout | Deferred commission, thresholds, monthly transfer | Cash, at the moment of sale |
| Relationship | Intermediated by the platform | Direct, data owned by the brand |
The most fundamental point remains the first. Opening the system to occasional customers, loyal customers, creators, and even your customers’ friends and family changes the network’s order of magnitude. We are no longer talking about a few thousand listed publishers, but your customer base and their circles.
This also resolves the question of trust, something no affiliate network has ever been able to generate. 88 % of consumers say they trust recommendations from people they know more than any other channel (Nielsen, Trust in Advertising 2021). An affiliate link posted by a stranger has never had access to that capital. A link sent by a friend has it by design, and that is precisely the topic of ‘Alternatively Influential’: Influence Without an Audience.
What this changes for your acquisition line
Once the network is open, the question becomes budgetary, and it is framed in reverse compared to usual.
With traditional affiliate marketing, you discover your customer acquisition cost after the fact, by aggregating commissions at variable rates. In a recommendation mechanic, you set the CAC upfront, and it doesn’t move. At Frak, on a CAC set at 10 €, 8 € go to the brand advocate and 2 € to the platform. No setup fees, no subscription: you only pay on completed sales.
Across the first onboarded brands, we observe an average 26 % drop in acquisition cost and, for some, up to 40 % of sales coming from recommendations. These are our numbers, based on our data, not a market average: take them for what they are, an estimate of what the channel delivers when properly equipped.
This logic builds on Customer Acquisition Is Broken: Anatomy of a Ceiling, extending what affiliate marketing figured out before everyone else: pay for what brings in customers. It simply got the identity of who brings them wrong. They are not just media outlets; they are people, which is the entire subject of From Creator Economy to Recommendation Economy.
It comes down to deciding whether you keep ‘doing affiliate marketing’ or finally treat recommendations as a full-fledged acquisition channel: scalable, trackable, and performance-based. The simplest starting point is often the referral program you already have that isn’t delivering: see Why Your Referral Program Isn’t Working.
Frequently asked questions
What is affiliate marketing?
It is a performance-based compensation model: a publisher places a tracked link to a merchant and earns a commission when a user clicks and buys. Born with the Amazon Associates program in 1996, it historically relies on a third-party cookie dropped at the time of the click to attribute the sale.
How much is the affiliate marketing market worth?
US advertisers spent 12,42 billion dollars on it in 2025, with an estimate of 13,81 billion in 2026 according to eMarketer. Globally, estimates vary significantly depending on the scope selected: Grand View Research values the affiliate marketing platform market alone at 22,6 billion dollars in 2025.
Does affiliate marketing still work without third-party cookies?
Partially, and less and less effectively. Browser protections and cross-device browsing break the last-click chain, and shares via private messaging arrive without a referrer. Modern mechanics replace third-party cookies with proprietary tracking, hosted by the brand rather than an intermediary network.
What is the difference between affiliate marketing and referral?
Affiliate marketing compensates vetted professional publishers with deferred commissions. Referral marketing rewards an existing customer who brings in a friend or family member, usually without vetting. Both pay on performance: an open recommendation mechanism brings them together by giving every customer the same tracked link as an affiliate.
