How Casino Affiliate Programs Work
A casino affiliate program pays you commission for sending new players to an online casino. You get a tracking link; when someone clicks it, registers and deposits, the casino credits that player to your account and pays you either a one-off fee (CPA), a share of the revenue they generate (revenue share), or a mix of both (hybrid).
That's the headline. What you actually take home depends on the details: how revenue is calculated, what's deducted, when a player qualifies and what happens in months when players win. This guide explains each piece, so you can read an affiliate contract with confidence.
How affiliate tracking works
- You get a tracking link from the program's dashboard. It contains your affiliate ID and usually a campaign tag.
- A visitor clicks it and lands on the casino. The program records the click, typically with a cookie or tracking parameter stored against your ID.
- They register. The new account is tagged to you, often permanently, so every future deposit counts towards your commission.
- They make a first deposit (an "FTD"). This is the event most deals are built around.
- Reporting shows clicks, registrations, FTDs and revenue by campaign, and commission is calculated at the end of each month.
Two features are worth insisting on:
- Sub-IDs: extra tags you add to a link (for example the page and position it sits in), so your reports show exactly which pages and buttons produce players.
- Postbacks: server-to-server notifications of registrations and deposits, so your own analytics can record conversions without relying on cookies.
The three commission models
| Revenue share | CPA | Hybrid | |
|---|---|---|---|
| What you earn | A percentage of NGR from your players, commonly 25–50% | A fixed amount per qualifying new depositor | A smaller CPA plus a lower revenue share |
| When you're paid | Monthly, for as long as players play | Once per player, after they qualify | Both |
| Risk | Income varies; winning months can go negative | Low: you know what each player is worth | Medium |
| Upside | Highest over time | Capped at the CPA | Balanced |
| Best for | Established sites with loyal audiences | New sites that need cash flow | Growing sites that want both |
Tiered revenue share is common: the percentage rises as you send more new depositors each month (for example 25% for 1–10 FTDs, 35% for 11–30, 45% above that). Check whether the tier applies to all your revenue or only to the players above each threshold.
For worked examples of what each model pays in practice, see how much casino affiliates make.
What "net gaming revenue" really means
Revenue share is only as good as the number it's calculated on. Programs usually start from gross gaming revenue (GGR), which is players' stakes minus their wins, and then deduct costs to reach net gaming revenue (NGR). Common deductions include:
- Bonuses and free spins given to your players
- Payment processing fees and chargebacks
- Gambling taxes and duties in the player's market
- Game provider or platform fees
- An "admin fee", often a flat percentage taken off the top
Two programs offering "40% revenue share" can pay very differently once deductions are applied. Always ask for the full NGR formula in writing before you send traffic.
Negative carryover explained
If your referred players win more than they lose in a month, your NGR for that month is negative. What happens next depends on the contract:
- With negative carryover, the deficit rolls into following months and is subtracted from future earnings until it's cleared. One lucky high-roller can wipe out months of commission.
- With no negative carryover, the balance resets to zero each month, so a bad month costs you that month only.
Some programs apply carryover only to players who've recently been active, or cap it. For smaller affiliates, a "no negative carryover" policy is one of the most valuable terms a program can offer.
Qualifying rules and payment terms
- Qualifying criteria (CPA "baseline"): the minimum deposit, total deposits or wagering a player must reach before you're paid. A high baseline means fewer of your players count.
- CPA caps: a maximum number of CPAs paid per month or per market.
- Payment schedule: most programs pay monthly, often 15–30 days after the month closes.
- Minimum payout: commission below a threshold rolls over to the next month.
- Payment methods and currency: bank transfer, e-wallets or crypto, and any fees or exchange costs.
- Lifetime vs limited terms: revenue share is usually for the player's lifetime, but some deals end after a set period.
- Change of terms: how much notice the program must give before changing your rates.
Marketing restrictions in your contract
Affiliate terms also control how you can promote a brand. Common restrictions include:
- No bidding on the brand's name in search ads
- Approved markets only: traffic from other countries may not be paid
- Approved bonus wording and mandatory significant terms
- Rules on email, SMS, social media and incentivised traffic
- Compliance with local advertising codes and responsible gambling rules. In Great Britain, see our guide to UK affiliate rules.
Breaking these terms is the most common reason affiliates have commission withheld, so read them before you build pages around a brand.
Direct programs vs affiliate networks
- Direct programs are run by the operator, often covering several sister brands. You get a dedicated affiliate manager and room to negotiate.
- Affiliate networks give you many brands through one account and one payment, which saves admin, but terms are less flexible and your relationship with each brand is indirect.
Many affiliates use both: networks to test brands quickly, and direct programs for the brands that perform best.
How to choose a casino affiliate program
Score each program against this checklist before you promote it:
| Check | Green flag | Red flag |
|---|---|---|
| Licensing | Licensed in every market you target | Unclear or offshore-only licence |
| Player experience | Fast withdrawals, fair bonus terms | Frequent complaints about blocked payouts |
| NGR formula | Deductions listed in writing | Vague "net revenue" with a high admin fee |
| Negative carryover | None, or capped | Unlimited and indefinite |
| Tracking | Sub-IDs, postbacks, reliable reports | Numbers that don't match your clicks |
| Payments | On time, low minimum payout | Late payments, changed terms without notice |
| Support | A named affiliate manager who replies | No contact beyond a ticket form |
Affiliate forums and fellow affiliates are the best source on payment reliability. A program that pays late to others will eventually pay late to you.
How to get approved
Most programs review applications manually. Affiliate managers want to see:
- A live site with real, original content in their markets. An empty template is usually rejected.
- Responsible gambling messaging, an 18+ notice and clear bonus terms.
- Honest traffic sources: SEO, streaming, community or email, with rough numbers.
- A professional contact email and complete payment details.

Frequently asked questions
How do casino affiliate programs work?
You share a tracking link from the casino. When a visitor clicks it, registers and deposits, they are credited to you and you earn commission, either a one-off CPA per new depositor, a percentage of the revenue they generate (revenue share), or a hybrid of both.
What is a CPA affiliate program?
A CPA (cost per acquisition) program pays a fixed amount for each new player who deposits and meets the qualifying rules, such as a minimum deposit. You are paid once per player, regardless of how much they play afterwards.
What is revenue share in casino affiliate programs?
Revenue share pays you a percentage, commonly 25–50%, of the net gaming revenue from players you refer, usually for as long as they keep playing. Net gaming revenue is player losses minus bonuses and other deductions set out in your contract.
What is negative carryover?
When your players win more than they lose in a month, your revenue share balance goes negative. Negative carryover rolls that deficit into future months until it is cleared. Programs with no negative carryover reset it to zero each month.
Do I need a website to join a casino affiliate program?
Most programs want to see a live website with original content, responsible gambling messaging and a clear traffic source before they approve you. Some accept streamers or social media creators, but a website makes approval much easier.
