How to Compare Casino Affiliate Programs the Right Way

What you are actually comparing

A casino affiliate program is a contract: you send traffic, the operator pays you a share of what that traffic produces. Simple enough. Then you read the terms and discover that “share”, “produces” and “pays” are all defined by the operator, in a document they can usually amend with 14 days’ notice.

That is why the current wave of “best partner program” reviews is only half useful. Rankings tell you which brands have good reputations. They rarely tell you how a program behaves in month seven, when your first cohort of players has stopped depositing and the negative balance from your sportsbook traffic is quietly eating your slots revenue. To compare casino affiliate programs properly you need a framework that survives that moment, not a leaderboard.

Four things do most of the work: how commission is calculated, how long your attribution lasts, how fast and reliably money actually arrives, and whether there is a competent human on the other end. Everything else is detail. Below are the assumptions that cost affiliates the most money, and what the terms usually say instead.

Myth: the highest revenue share wins

A 50% headline rate on a narrow definition of net revenue can pay less than 30% on a generous one. The percentage is the smaller half of the equation; the deductions are the bigger half.

Read the definition of net gaming revenue line by line and note what gets subtracted before your cut is calculated. Common deductions include bonus and free-spin costs, payment processing fees, gaming duties and licence levies, affiliate-attributed chargebacks, jackpot contributions, provider royalties, and a flat “administrative fee” of a few percent that exists for no reason anyone will explain to you.

Then check the tiering. Revenue share offers are commonly advertised as a band, starting in the mid-twenties and stepping up toward 40% or more at volume. The question is what resets. A tier that recalculates monthly on first-time depositors means a slow February pushes you back to the bottom rate for the whole month, including on players you referred two years ago. A tier that locks in once achieved is worth meaningfully more than a higher headline number that resets.

Three clauses deserve a hard look before you sign anything:

• Negative carryover. If a referred player wins big, your balance goes negative. With carryover, that deficit follows you into following months until it clears. Without it, the slate wipes at month end. On small volumes this single clause swings earnings more than ten percentage points of revenue share.
• Brand bundling. Some groups net your results across every brand in the portfolio. Good when one brand carries another, painful when a single whale drags down four profitable brands at once.
• Product weighting. Live casino, sportsbook and poker usually pay a lower effective rate than slots, sometimes through a separate schedule. If your audience plays live tables, the slots-led headline rate is not your rate.

Commission types, side by side

Most programs offer some mix of four structures. None is inherently better; they price risk differently, and the right one depends on whether you can afford to wait.

CPA is often sold as the safe option because the money is fixed and arrives early. The conditions are where it gets interesting: a qualifying player typically has to clear a minimum deposit, complete KYC, and sometimes wager a multiple of that deposit before you are paid, and many agreements let the operator void or claw back commissions on traffic it judges to be low quality, duplicated or bonus-hunting. Ask what percentage of CPA conversions were rejected last quarter. A program that can answer is already a better program.

Myth: a lifetime cookie means a lifetime player

Two different numbers get called the same thing, and confusing them is expensive. Cookie duration is how long after a click you still get credited if the visitor returns and registers. Lifetime revenue share is how long you keep earning once that player is attributed to you. A program can offer a lifetime revenue share with a 30-day cookie, or a 90-day cookie with a 24-month earnings cap. Check both.

Typical cookie windows run 30, 60 or 90 days, with some programs advertising unlimited or “lifetime” attribution. In practice, browser restrictions on third-party cookies, people switching from phone to desktop, and app installs that bypass the web tracker all shorten the real window. What matters more than the stated number is the attribution rule behind it: last click is the norm, so if a player clicks your link, then clicks a comparison site’s link a week later, the other site gets the player. Ask whether attribution is first or last click, whether direct type-ins after a click count, and how app installs are tracked.

Also look for the earnings tail. Some agreements stop paying revenue share on a player after 12 or 24 months, or after a period of inactivity. If your model depends on long-lived players, that clause is the one to negotiate hardest.

Myth: everyone pays monthly, so payout speed is a non-issue

Payout speed is the gap between a player losing money and you being able to spend your share of it. Monthly reporting does not mean monthly cash. A program that closes the month, reviews for a fortnight, then pays on net terms can sit 45 to 60 days behind the activity that earned it, and that is the honest version.

What to pin down before you commit budget:

1. The schedule. Calendar month close, then payment by a stated date. Written in the terms, not promised in a chat window.
2. The minimum threshold. Often around the equivalent of 100 units of the account currency. Below it, your balance rolls over, which is fine until you want to leave the program with 70 units stranded.
3. Methods and fees. Bank transfer, e-wallet, crypto. Who absorbs the transfer fee, and what exchange rate applies if you earn in one currency and bank in another.
4. Hold and review practice. Ask directly whether commissions are ever withheld pending fraud review and for how long. Then ask two affiliates who are already in the program.
5. Dormancy clauses. Some agreements stop accruing, or zero the balance, if you send no new players for a defined period. Read that one twice.

Payout reliability, not payout speed, is the real ranking factor. A program that pays on day 35 every single month beats one that pays on day 20 whenever it feels like it.

Myth: support quality is a soft factor

It is the factor that decides whether the rest of your comparison means anything. Commission terms are only as good as the person willing to apply them when something breaks, and something always breaks: a tracking link stops firing, a geo gets restricted overnight, a landing page 404s during your best campaign week.

Judge affiliate support quality on evidence, not vibes. Does the dashboard show real time data or yesterday’s? Can you pass subIDs through to player level and pull them back out in a report or via API? Are creatives localised and current, or is the banner pack three years old? Does your manager reply within a working day with an answer rather than an acknowledgement? Send a deliberately awkward question during onboarding, something about negative carryover on a specific brand, and time the response. That reply tells you more than any review score.

One more test: ask how you will be notified if terms change. A program that commits in writing to notice periods and grandfathering of existing player cohorts is signalling something about how it intends to behave.

Myth: a licensed brand makes you compliant

The operator’s licence covers the operator. Your advertising is your problem. Regulated markets impose their own rules on how gambling can be promoted, what bonus claims are permitted, how odds and terms must be disclosed, and who may be targeted. Programs differ sharply in how much of this they help with: some supply approved creative and market-by-market guidance, others hand you a link and an indemnity clause.

Build the compliance questions into the comparison itself. Which territories are permitted, and which are explicitly excluded? Are brand bidding and search terms restricted? What responsible gambling messaging and age gating must appear on your pages? Does the program require you to carry self-exclusion information and avoid implying that gambling is a way to make money? Those requirements are not obstacles to work around; they are the baseline for promoting products that carry a built-in house edge, where most players lose over time, and getting them wrong can cost you the account and more.

Running the comparison instead of reading about it

Score programs on the four axes with weights that match your own model, then verify with money. Take two or three shortlisted programs, split comparable traffic across them for a full quarter, and track first-time depositors, revenue per player, rejection rates, actual payment dates and support response times in your own spreadsheet rather than theirs. Keep raw subID data so you can audit attribution independently.

A quarter of real data will contradict at least one thing you believed from a review page, and that contradiction is the whole point of doing the comparison yourself. Earnings in this business are not guaranteed by anyone’s commission table; they are what is left after the deductions, the clawbacks, the carryover and the 45-day wait.
