86% of affiliate programs pay the last click. The creator who sold them gets nothing.
A creator writes a 3,000-word review of your brand. Photographs the product. Publishes it. A hundred people read it. One of them gets to your checkout, hesitates, opens a new tab, and searches for a coupon code. They find one on RetailMeNot. They buy. RetailMeNot gets the commission. The creator gets nothing.
That's not an edge case. That's how 86% of affiliate programs globally operate right now.
- 86% of affiliate programs worldwide run on last-click attribution, the model that pays whoever was present at checkout, not whoever drove the sale.
- Coupon sites, browser extensions, and cashback apps are structurally positioned to win last-click. They do no demand creation. They just show up last.
- The bloggers and creators actually building intent for your brand rarely see commission because they weren't the final click.
- Fixing this means switching attribution models and auditing your publisher list. Both are possible without rebuilding your program from scratch.
I've looked at affiliate dashboards for clients where RetailMeNot, Honey, and CouponCabin were the top three earners every single month. When we traced those orders back through the customer journey, most of the buyers had already decided to purchase before they searched for a code. The coupon site didn't sell them anything. It just showed up at the right moment and collected a commission for it. That's the affiliate attribution problem in one example.
How last-click attribution actually works
When a customer buys, your affiliate platform asks: which affiliate link did they click last? That affiliate gets 100% of the commission. Everything that happened before, every piece of content that introduced the customer to your brand, every review they read, every YouTube video they watched, counts for nothing in the commission calculation.
The mechanism is simple and the flaw is obvious once you see it. But most ecommerce brands never audit their affiliate data at this level. They see "affiliate channel: $X revenue, $Y commission paid" and call it a profitable channel. The question nobody asks is who got paid and whether they earned it.
U.S. affiliate spending is growing fast. Most of that growth is going to publishers that capture demand rather than create it. The total spend number looks like a healthy, expanding channel. The underlying allocation tells a different story.
Who your affiliate program is actually funding
Last-click attribution produces a predictable winner: whoever is present at the moment of purchase. That's usually a coupon site, a browser extension, or a cashback app.
RetailMeNot, Honey, CouponCabin, Capital One Shopping, Rakuten. These are not content publishers. They don't write reviews. They don't introduce your brand to new audiences. Their entire business model is to intercept customers who are already in the decision-made phase and offer them a small discount in exchange for a click.
Honey is installed in hundreds of millions of browsers. The moment a customer gets to checkout, it activates, looks for a code, applies one or fails quietly, and the affiliate cookie fires. Your affiliate platform records a conversion credited to Honey. Honey collects the commission. You get back a fraction of it as a "sale." And you've just paid for a customer you were already going to get.
Log into your affiliate platform. Sort by commission paid. If RetailMeNot, Honey, CouponCabin, or Capital One Shopping are in your top five earners, you're not running an affiliate program. You're running a coupon program and paying for demand you already captured.
The publishers doing the actual work
Meanwhile, the people actually building buying intent for your brand are doing it for free. The blogger who wrote a 2,000-word honest review. The YouTuber who unboxed your product and answered every objection in a 12-minute video. The niche newsletter writer who mentioned your brand to an audience of 8,000 exactly the right kind of buyers.
These publishers introduced your brand. They created the intent. They sent the customer into the funnel. And then, right before checkout, a coupon browser extension fired and claimed the sale.
Your best real affiliate probably isn't even in your program. They sent you traffic, the customer bought three weeks later using a RetailMeNot code, and you have no record that the content ever existed. The attribution gap between demand creation and demand capture is the most expensive blind spot in DTC affiliate programs.
This is the same structural issue that makes your Meta attribution look broken — the platform that gets credit isn't always the platform that drove the decision. In affiliate marketing, the problem is built into the attribution model itself.
How to tell if this is happening to you
Three things to look at in your affiliate data right now.
Publisher composition.Sort your top 10 earners by total commission paid over the last 90 days. If coupon, cashback, or browser-extension publishers appear in the top half, that's the signal. Demand-creation publishers (bloggers, review sites, newsletters, YouTube channels) should dominate this list if your program is working correctly.
Time-to-purchase.Most affiliate platforms show the gap between the affiliate click and the purchase. Last-click capture publishers produce very short click-to-purchase windows, often under five minutes, because they intercept customers mid-checkout. If the bulk of your affiliate revenue comes from sub-five-minute click-to-buy windows, it's predominantly capture.
Customer overlap. Pull the email addresses of your affiliate-attributed customers and cross-reference with your email list. If a high percentage are already subscribers, they were existing customers, not new ones. Affiliates earning commissions on your own email list are a clean definition of mispaid commission.
If any of these check out, your affiliate program is allocating spend to the wrong publishers. The good news: it's fixable without tearing the program down. It just requires a hard look at what your dashboard is actually telling you.
How to build an affiliate program that pays for demand creation
Switch your attribution model. First-click attribution pays the publisher who introduced the customer, not the one who showed up last. Position-based attribution (often 40/20/40) splits credit across the first touch, middle touches, and final touch. Multi-touch pays every affiliate that contributed. Any of these is more accurate than pure last-click.
Not every affiliate platform supports custom attribution models. Impact, Partnerize, and ShareASale's advanced tiers do. If your current platform is locked to last-click only, that's worth factoring into your next platform decision.
Exclude or cap coupon publishers. Most affiliate platforms let you define publisher categories and set different commission rates or eligibility rules by category. Coupon and cashback sites can be excluded entirely or paid a reduced flat-rate rather than a percentage commission. This alone shifts incentives toward demand-creation publishers.
Recruit the publishers doing the real work.Search for your brand name in Google, YouTube, and Reddit. Find the bloggers and creators who are already writing about you without being in your program. Reach out. Bring them in at a higher commission rate. Pay them for what they're already doing.
Set coupon code rules.If you issue affiliate coupon codes, make them publisher-specific and non-transferable. A code that belongs to a specific blogger shouldn't be indexable by RetailMeNot. Some brands use platform-level protections for this; others handle it through code generation and monitoring.
Done right, affiliate marketing is one of the only paid channels where you pay only for incremental revenue. It's worth getting right. If you're evaluating whether your whole performance marketing setup is structured correctly, understanding your marketing agency alternatives is where most DTC founders start.
The bottom line on affiliate attribution
Last-click attribution is the default because it's simple. One click, one commission, one payment. No complexity. No arguments about who deserves credit. But simple doesn't mean accurate, and inaccurate attribution means misallocated spend.
86% of affiliate programs are built on this model. That means most DTC brands are paying commissions to publishers that intercept demand rather than create it, while the people actually building intent for their brand earn nothing.
Your affiliate dashboard shows revenue and commission paid. It doesn't show you whether the publishers earning that commission created a single new customer or just collected a toll on traffic that was already coming.
That's what you need to know. And now you know how to check.
Frequently asked questions
What is last-click attribution in affiliate marketing?
Last-click attribution assigns 100% of the commission to whichever affiliate link the customer clicked last before purchasing, regardless of what content actually introduced them to your brand. In practice, this almost always rewards coupon sites and browser extensions that activate right before checkout, not the bloggers, creators, or review sites that drove the initial interest.
How do I know if coupon sites are eating my affiliate commissions?
Log into your affiliate platform and sort your top earners by commission paid. If RetailMeNot, Honey, CouponCabin, or Capital One Shopping appear in your top five, you're funding demand capture rather than demand creation. These tools insert themselves right before checkout and claim the commission for customers who were already going to buy.
What attribution model should ecommerce brands use for affiliate programs?
First-click or position-based attribution models reward the affiliate who introduced the customer, not just the one who was present at checkout. Multi-touch attribution is more accurate still: it splits commission across every affiliate touchpoint in the customer journey. If your affiliate platform only offers last-click, look at Impact, Partnerize, or ShareASale's advanced tiers. Each supports custom attribution models.
Is affiliate marketing worth it for small ecommerce brands?
Yes, but not with a default last-click setup. An affiliate program running last-click with no publisher vetting pays commissions on customers you would have kept anyway. Built correctly, with editorial and creator publishers, first-click or multi-touch attribution, and explicit coupon-site exclusions, affiliate becomes one of the few channels where you only pay for incremental revenue.
