The Affiliate Model: CPA, Revshare & Hybrid

Operators rarely acquire their own players; they pay affiliates — third-party marketers such as comparison sites, streamers and tipsters — a commission for the players they send. That commission takes three main shapes: a one-off CPA fee, an ongoing revenue share of the players' net losses, or a hybrid of both. This is a neutral look at how the channel pays out, how referrals are tracked, and why a payment model tied to player losses is exactly why advertising and responsible-gambling rules bear down on it so hard.

Most licensed operators do not find their own players. They rent reach from affiliates — independent marketers such as comparison sites, streamers and tipster channels — who send traffic to an operator in exchange for commission on the players they refer. The operator supplies the product, the licence and the payout terms; the affiliate supplies the audience and the persuasion. Because it is a performance model, the operator usually pays only when something measurable happens, which shifts marketing risk onto the affiliate and makes the cost of acquiring a player easier to control. The trade-off is a different kind of exposure: the operator remains answerable for whatever its affiliates publish. Understanding the three commission structures below matters because each one quietly decides who is paid to chase sheer volume, who is paid to chase player quality, and who is left carrying the compliance risk when a corner is cut. None is inherently fairer than another; each simply moves risk and incentive to a different place in the chain.

Three commission structures dominate. Under CPA (cost per acquisition), the operator pays a fixed, one-off fee the moment a referred player meets a condition — typically registering and making a first deposit. The affiliate earns the same whether that player stays a week or a year, so CPA rewards volume over quality. Under revenue share, the affiliate instead earns an ongoing percentage of the net revenue the referred players generate — a cut of those players' losses, for as long as they keep playing. A hybrid deal blends the two: a smaller upfront CPA plus a smaller revenue-share tail on the same players. A short illustration makes the difference concrete. Suppose a referred player deposits and loses £40 net over a year. A £50 CPA deal pays the affiliate £50 once, whatever happens next. A 30% revenue-share deal instead pays 30% of that £40 — £12 — and keeps paying a share of every future loss. CPA front-loads a certain, capped payment; revenue share is smaller at first but open-ended, and worth more the longer and harder a player loses.

Revenue-share deals settle month by month, which raises an awkward question: what happens in a month when the referred players win? The operator's net revenue from that cohort can turn negative — the players took more out than they put in. Negative carryover is the contentious clause that answers it. Rather than resetting the affiliate's balance to zero and starting the next month fresh, the operator carries that negative figure forward and deducts it from the affiliate's next revenue-share payments, until the deficit is worked off. The affiliate therefore absorbs part of the downside when players win, but shares only a slice of the upside when they lose. Whether carryover applies at all — and whether a new month zeroes the balance — is one of the most negotiated points in an affiliate contract, and a frequent source of dispute. It exists because the underlying revenue being split can genuinely be negative; it is contentious because it ties the marketer's pay even more tightly to players losing rather than winning.

Before anyone is paid, a referral has to be attributed — matched to the click that produced it. Because gambling traffic is privacy-restricted and browser pixels drop or misfire, the industry standard is server-to-server (S2S) postback tracking, where events are reported machine-to-machine rather than in the browser. A tracked click carries a unique identifier. When that visitor registers and later makes a first deposit, the operator's server 'posts back' those milestones to the affiliate's tracking platform, which matches them to the originating click and releases the agreed payment. The funnel that decides who earns what runs click → registration → first deposit → ongoing net revenue. This plumbing is invisible to the player but decisive commercially: real money hangs on which system saw the click first, so attribution disputes are common. It also explains why the channel generates so much data about individual players — every step from first tap to lifetime losses is logged and reconciled so the commission can be calculated.

Line the structures up and one fact stands out. A revenue-share affiliate's income rises and falls with the net revenue of the players they referred — and that net revenue is simply those players' losses. The more a referred player loses, and the longer they keep losing, the more the affiliate earns; negative carryover sharpens the same incentive by penalising the affiliate when players win. That alignment is exactly why the channel is fenced so tightly. In the UK, affiliate content is treated as advertising the operator is responsible for: it must be strictly 18+, clearly labelled as marketing, must not be of strong appeal to under-18s, and must never imply gambling is a way to make money or solve financial problems (CAP Code, Section 16). Responsible-gambling standards and the operator's licence conditions apply to the acquisition it drives, not only to the product itself. It is also why a genuinely independent, non-promotional resource — iGamer among them — deliberately takes no affiliate money and carries no affiliate links: the moment a resource earns a share of players' losses, it is no longer describing the model from the outside. This is education about the industry, for adults aged 18 or over, not an invitation to join it.
