iGaming affiliate marketing: how it works

iGaming affiliate marketing is a performance channel: publishers send players to betting and casino operators, and are paid when those players complete an agreed action.

The vocabulary is where deals separate. RevShare, CPA, hybrid, CPL, fixed fee and sub-affiliate override each describe two things — when money is released, and what the amount is calculated from. Two contracts quoting the same percentage can pay differently, because the base underneath the percentage is defined in the agreement rather than by the industry.

A RevShare percentage is the share of net gaming revenue paid on referred players, and NGR is whatever that contract lists as deductions. There is no industry percentage. Gambling.com Group describes revenue share as a percentage of NGR from a pool of referred players. Two agreements at the same headline rate pay different amounts once bonuses, fees and tax enter the base.

What iGaming affiliate marketing is

An affiliate publishes content or media carrying a tracked link to an operator, and earns commission on players who arrive through it. Gambling.com Group, a listed affiliate, describes the arrangement in its annual filing: an online gambler who visits an operator from one of its websites, registers an account and deposits becomes a referred player, and each referred player entitles the affiliate to remuneration under the agreement with that operator.

The channel exists because acquisition risk moves. An operator paying per referred player converts part of its marketing budget from a fixed cost into a variable one; the publisher takes on the cost of building and holding the audience.

How a referral becomes a payment

Four steps run between a click and a payout, and each is governed by the program’s terms rather than by convention.

An affiliate applies to a program, and regulated-market programs verify identity before activation. The affiliate receives a tracked link, with attribution handled by browser cookies, server-to-server postbacks or both. A referred user completes the qualifying action defined in the agreement — usually a first deposit meeting a minimum value and verification conditions. The program then calculates commission on its own reporting and pays on its own cycle.

Accounting treatment shows where certainty differs between models. Gambling.com Group recognises CPA fees when the referral is accepted by the operator, while revenue-share fees are treated as variable consideration and recognised only to the extent that a significant reversal is unlikely. One model settles at the point of referral; the other stays open to the referred players’ later results.

Commission models

Six structures cover almost every iGaming affiliate agreement, and they differ in the trigger, the base and the risk each side carries.

The first three definitions come from the same filing. Gambling.com Group defines CPA as a single cash payment for each referred player meeting agreed criteria, revenue share as a percentage of the NGR produced by a pool of referred players, and hybrid as a combination of both per referred player.

The other three appear in public program terms. Roobet’s affiliate terms define CPL as a one-time fee for referring a new customer under conditions agreed in writing. Roobet’s affiliate program set a sub-affiliate override at 5% of the commission generated by each approved affiliate a master affiliate recruits — released only after that sub-affiliate has referred five new depositing customers, and carrying any negative balance the sub-affiliate inherits. Fixed fee sits outside the referral logic: Better Collective reports banner revenue as either CPM or “direct fixed fee agreements” with customers.

The full comparison of CPA against RevShare on a single cohort — payback timing, clawback exposure and what happens as player value accumulates — sits on the RevShare page. The relevant point here is that a CPA rate and a RevShare percentage answer different questions and cannot be compared as numbers.

What the revenue base does to a RevShare rate

RevShare is paid on net gaming revenue, and no universal definition of that base exists. Gambling.com Group states that NGR under its agreements is gross gaming revenue for a user adjusted for direct costs such as transaction fees, bonuses and taxation, and that those costs can rise — for example through new tax regulation — after a deal is signed. Roobet’s published terms define NGR as gross gaming revenue less progressive contributions, non-cash incentives, chargebacks, balance adjustments, costs and taxes. Two 30% deals written against those two definitions are not the same deal.

Pooling changes the arithmetic again. Referred players are typically pooled per affiliate account, so a single large winning player can zero out the commission payable on every other player in that account for the month. What happens next is contractual: Roobet resets a negative month to zero unless otherwise agreed in writing, then carries forward the deficit of any individual player who lost the program $10 000 or more, offset only against that same player’s future revenue.

Tiers are a modifier, not a model

A rate that rises as volume rises is a schedule attached to RevShare or CPA rather than a seventh structure. How the thresholds work, and what resets them, sits on the affiliate commission tier page.

What the mix looks like in public reporting

Two listed affiliates disclose their model split, and both figures describe one company’s contract mix in one year rather than a market average. Better Collective reported 2025 revenue of €336.7M, with revenue share at 47%, CPA at 24%, subscription sales at 5% and other income at 24%. Raketech reported for continued operations in 2025 that revenue share made up 47.4% of revenue, upfront payments 27.3% and flat fees 23.7%.

Neither split is a benchmark for a program negotiation. They show that the models coexist inside a single business and that the balance between them shifts year to year.

Where the demand behind a deal comes from

Affiliate contracts price acquisition, and the demand available to acquire is not evenly spread. Blask data for H1 2026 shows demand up 46.8% year on year in Nigeria and 15.8% in Brazil, against −5.3% in the United States and −11.6% in Germany.

Blask’s acquisition benchmark quantifies what a market position supports rather than what a program pays. Acquisition Power Score for the United States averaged 556.0K potential new customers a month across H1 2026, in a range of 306.8K to 1.30M. That figure is a market estimate, not a deposit count: an affiliate invoice settles on the operator’s record of a qualified first-time deposit, which no external model observes.

Who carries the compliance risk

Under the UK Gambling Commission’s social responsibility code 1.1.2, licensees are responsible for the actions of third parties they contract with for any aspect of the licensed business. They must contract on terms requiring those third parties to conduct themselves as if bound by the same licence conditions and codes of practice. Also, they must be able to terminate promptly — a provision that names affiliates who have breached an advertising code.

The commercial consequence is written into program terms. Because the licence risk sits with the operator, creative approval, content standards and immediate termination clauses appear alongside the commission schedule, and an affiliate manager enforces both.

FAQ

Bottom line

An affiliate payout model is a rule about timing and base, not a rate. RevShare, CPA, hybrid, CPL, fixed fee and sub-affiliate override allocate acquisition risk differently between publisher and operator, and the deduction list, pooling rule and qualification conditions decide what the headline number turns into. The percentage is the last thing worth comparing.
