We run it as a partner portfolio measured on incrementality — commissioned by partner type and new-customer value, policed for fraud, and proven with holdouts, not last-click. $ 0 US affiliate spend in 2024, +49.8% since 2021 0 of all US e-commerce sales run through affiliate + 0 higher average order value from affiliate-sourced buyers By David Schaefer · [LinkedIn](https://www.linkedin.com/) · Updated June 2026 ## The dashboard is *lying to you.* Flip the view. Coupon, cashback, and brand-bidding partners fire at the checkout and claim sales you’d have won for free. Strip out what wasn’t incremental and the heroic ROAS shrinks to the truth. Tap to switch the view Dashboard ROAS True incremental ROAS 8.0× What the network dashboard reports — every last-click sale credited to affiliate. Looks unbeatable. When eBay halted branded paid search, 99.5% of the traffic still arrived (Blake, Nosko & Tadelis, Econometrica 2015); a retailer geo-holdout cut affiliate’s true credit from ~18% to ~9% of revenue (IREV, 2025). Figures illustrative.[1](#src) ## Incrementality lives in the *partner.* Affiliate isn’t a channel — it’s a portfolio of very different businesses. Tap a partner type to see whether it creates demand or just skims credit, what it costs, and how to use it. Tap a partner type Content, creator, and email partners create net-new demand; coupon, cashback-extension, loyalty, and brand-bidding partners largely capture existing intent at checkout (impact.com, Partnerize, PMA, 2024–25). Verdicts are RGM analysis.[2](#src) ## Your true ROAS, after *cannibalization.* Set your reported numbers and your partner mix. The more budget sitting with coupon, cashback, and brand-bidding partners, the more of your “affiliate revenue” would have happened anyway. Watch the honest number appear.

Illustrative — we run the real holdout on your data.[3](#src) ## One flat rate is *leaving money on the table.* Drag the new-customer mix. Paying every partner the same percentage rewards the ones intercepting your existing buyers. Pay more for new customers and less for repeat checkout-skimmers, and the same budget buys real growth. Share of orders that are NEW customers 35% — flat-rate cost per NEW customer — smart-commission cost per NEW customer — saved & redeployed — budget now driving new customers Commission-by-partner-type and new-customer bonuses are established remedies; affiliate AOV rose to ~$123 (+4% YoY) even as transactions fell ~5% (impact.com, 2025).

Pick the model to see what it’s for, what it costs, and which players fit — the right answer usually changes as the program matures. Affiliate network cold start SaaS platform control Agency / OPM managed Networks charge an override on payouts (costlier at scale); SaaS partnership platforms charge a fixed fee (cheaper as you grow); impact.com runs $100B+ in partner-referred GMV, PartnerStack $2.7B in B2B GMV (company reports, 2024–25).[5](#src) ## Run it like a *program.* Affiliate isn’t set-and-forget on a network’s autopilot — it’s a recruit, structure, police, and prove loop. Each step has its own job. Tap through it. RGM partner-program method — recruit the right partner mix, commission by type and customer status, police fraud, prove incrementality.

Cookie-stuffing extensions, brand-bidding, and bot traffic quietly siphon commission — the Honey scandal showed even mainstream tools hijack credit. Unpoliced, a real slice of every payout is waste. Tap to police the program Unpoliced Policed Affiliate fraud / invalid traffic is estimated from ~17% (CHEQ, 2022) to far higher by some vendors; Rakuten removed PayPal-owned Honey and Google banned no-discount affiliate extensions (2025–26). Grid illustrative.[7](#src) ## Stack the *evidence.* Only about a fifth of marketers still trust last-click. Click each way you can prove a partner actually caused a sale — the more causal the method, the more you can trust the call to pay or cut. Click the methods you use guessing decision-grade Only 21.5% of marketers believe last-click reflects true impact and 74.5% are moving away from it (eMarketer × Snap, 2024); server-side postback is the affiliate attribution standard. Layer new-vs-returning, holdouts, and MMM.[8](#src) ## Five ways brands waste *affiliate budget.* Most wasted affiliate spend fails the same handful of ways. Open each one. 1 · Paying last-click at face value + The network dashboard credits every last click to affiliate, including sales you’d have won anyway. Run a holdout, commission on incrementality, and reward new customers — not the coupon that fired at checkout. 2 · One flat commission for every partner + A content site that creates demand and a cashback extension that intercepts it are not worth the same rate. Commission by partner type and customer status, or you subsidize the skimmers. 3 · Letting affiliates bid on your brand + Brand-bidding partners buy the traffic you’d win for free and bill you for it. Police trademark terms and typosquatting, and enforce the policy with monitoring, not good faith. 4 · Ignoring cookie-stuffing extensions + Toolbars and extensions can overwrite the legitimate partner’s cookie at checkout — the Honey scandal in miniature. Vet partners, block the skimmers, and validate conversions server-side. 5 · Treating it as set-and-forget + Autopilot programs decay into coupon dependence. The value is in active recruitment of demand-creating partners and managing the relationships like the media businesses they are. Synthesis of the eBay experiment, geo-holdout, impact.com, PMA, and the Honey/Chrome developments cited throughout — RGM analysis.[9](#src) ## A partner portfolio, *proven.* No coupon dependence, no last-click vanity, no autopilot. A senior team recruits demand-creating partners, commissions by type and new-customer value, polices fraud, and proves incrementality with holdouts. Pricing is custom: flat, project, or performance, by fit. 01 STEP 01 ##### Recruit the mix Hunt demand-creating content, creator, and email partners — not just whoever’s already in the network. 02 STEP 02 ##### Commission & police Rates by partner type and new-customer value; brand-bidding and cookie-stuffing shut down. 03 STEP 03 ##### Prove & scale Holdouts, new-vs-returning, and server-side tracking — then re-invest in the partners driving real lift. Pay for growth, not for the checkout click. RGM engagement model — senior-led, incrementality-first, fraud-policed, custom pricing. RGM analysis.[10](#src) ## Questions buyers *ask.* **What is affiliate and partnership marketing?** A pay-for-performance channel where third-party partners — content and review sites, creators, loyalty and coupon sites, email partners, and B2B referrers — drive sales or leads for a commission. Modern programs treat it as a portfolio of partner relationships managed on a network or SaaS platform, not a single ad buy. **How is affiliate marketing priced?** Usually as a commission on the sale, with cost per acquisition or per lead common in finance and B2B, and recurring commissions in SaaS. Rates vary widely by vertical, from low single digits in electronics to 20–50% for software and courses. We commission by partner type and customer status rather than one flat rate. **What is the affiliate cannibalization problem?** Coupon, cashback, loyalty, and brand-bidding partners often take last-click credit for sales that would have happened anyway. When eBay halted branded paid search, 99.5% of the traffic still arrived; a retailer geo-holdout found affiliate’s true incremental contribution was about half of what the dashboard credited. We pay for incremental sales, not the click at checkout. **How do you measure affiliate incrementality?** With geo or audience holdouts, new-versus-returning customer analysis, server-side postback tracking, and media-mix modeling — not last-click alone. Only about a fifth of marketers still trust last-click. Incrementality is a property of the partner type, so we measure and commission accordingly. **Should we use an affiliate network or a SaaS platform?** Networks solve the cold-start problem with a ready partner pool and are priced on an override. SaaS partnership platforms give a brand more control and data for a fixed fee as the program matures. Many brands start on a network and migrate to SaaS; we manage either and recommend by program stage. **How do you prevent affiliate fraud?** By policing brand-bidding and trademark abuse, blocking cookie-stuffing browser extensions, vetting partners and traffic sources, and validating conversions server-side. Affiliate fraud and invalid-traffic estimates run from roughly 17% to far higher, and the Honey scandal showed even mainstream extensions can hijack attribution. ## Pay for growth, not the checkout click. *Ever.* We take a handful of brands that want an affiliate program built on incremental sales, not a dashboard that flatters itself.
