The commission model you choose does more than determine how much you pay publishers โ it fundamentally shapes which publishers join your program, how they promote you, and what kind of traffic quality you attract. Choosing the wrong model is one of the most common and costly mistakes in affiliate marketing.
CPA โ Cost Per Acquisition
CPA pays a fixed amount per completed action โ a purchase, subscription, or sign-up. It is the most common model in performance marketing because risk is fully on the publisher side: you only pay when value is delivered.
CPA without quality controls attracts publishers who optimise for quantity over quality. Set minimum conversion thresholds, chargeback caps, and quality score requirements โ or you will pay for conversions that generate zero long-term customer value.
CPL โ Cost Per Lead
CPL pays for a qualified lead โ an email sign-up, form submission, or trial request โ without requiring a purchase. This is ideal for high-consideration purchases (mortgages, insurance, B2B software) where the sales cycle is long and the advertiser's sales team closes the deal.
Set strict lead quality criteria upfront: minimum data fields required, email validation, phone number verification, duplicate suppression window, and maximum age of lead. Loose criteria invites form-stuffing and bot submissions that look like leads but have zero commercial value.
CPS โ Cost Per Sale
CPS pays a percentage commission on actual revenue โ the standard model for e-commerce affiliate programs. The percentage naturally aligns publisher incentives with order value, encouraging promotion of higher-ticket items and full-price sales over discounted ones.
| Vertical | Typical CPS Rate | Notes |
|---|---|---|
| Consumer Electronics | 3โ8% | High AOV, low margins |
| Fashion & Apparel | 8โ15% | Mid margins, high returns rate |
| Digital Products | 20โ50% | Zero COGS โ generous CPS viable |
| Health & Beauty | 10โ20% | Strong repeat purchase potential |
| Travel | 3โ10% | High AOV compensates low % |
RevShare โ Revenue Share
RevShare pays publishers a recurring percentage of the revenue their referred customers generate โ monthly, for the lifetime of the customer or a defined period. Common in SaaS (15โ30% MRR) and financial services (trailing commissions on premiums).
RevShare attracts the highest-quality publishers because the long-term earning potential rewards genuine audience trust and careful audience selection. A publisher who sends 10 high-quality SaaS sign-ups earns recurring commissions for years โ incentivising them to only send users who will actually stay subscribed.
Publishers on RevShare structures have a 4ร lower annual churn rate than publishers on CPA-only programs. Once a publisher starts earning recurring commissions, switching to a competitor's CPA offer becomes economically irrational.
Hybrid Models
The most sophisticated programs combine models. A SaaS company might pay a $50 CPA on trial sign-ups plus 15% RevShare on months 1โ12. An e-commerce brand pays a $5 base CPA plus 8% CPS โ the base attracts volume publishers, the percentage rewards quality. Hybrid models reduce churn in your publisher mix and improve long-term publisher lifetime value.
Which Model Should You Use?
| Business Type | Recommended Model |
|---|---|
| E-commerce | CPS (% of sale) + optional base CPA for top publishers |
| SaaS / Subscription | CPA on trial + RevShare on recurring MRR |
| Finance / Insurance leads | CPL with strict quality criteria and validation |
| Mobile apps | CPA on install + optional CPA on first purchase (dual-event) |
| Content / Media | CPL (email sign-ups) or CPS on digital product sales |
