A bookmaker affiliate license is a revenue-sharing contract, not a marketing gig. You refer players, the operator tracks their betting activity, and you get paid a percentage of what those players lose after winnings are paid out. That single mechanic, commission on net losses rather than on deposits, decides whether your affiliate business prints money or bleeds it. This primer walks through how the model actually works, where the traps sit, and what to check before you sign anything.
What a bookmaker affiliate license actually pays you
Strip away the branding and an affiliate program is a ledger. The operator records every bet your referred player places, subtracts every payout they receive, subtracts any bonus money the player was given, and arrives at a net revenue figure. Your commission is a slice of that number. If the player deposits $500 and loses it all with no bonuses involved, at a 30% rate you earn $150. If the same player deposits $500, wins $900, and withdraws, your balance goes negative by roughly $120 depending on how the operator handles it.
Published rates usually sit between 20% and 40%, and the spread is not random. Higher rates come with conditions: minimum monthly active players, traffic quality thresholds, or a negative carryover clause that lets the operator deduct your losing months from future earnings. A 40% deal with negative carryover can pay less over a year than a flat 25% deal without it. Read the terms, not the headline percentage.
Deposits are not revenue. This is the mistake that kills new affiliates. A player who deposits $2,000 and grinds low-stakes sports bets at tight margins might generate $40 of net revenue for the operator over three months. At 30%, that is $12 for you, minus any fees. Meanwhile a $50 deposit from a casual slots player on high volatility games can vanish in an evening and pay you $15 in one day. Volume of deposits tells you almost nothing about your earnings.
Revenue share versus CPA and hybrid deals
Most programs offer three structures. Revenue share pays a percentage of net losses indefinitely, which means a good player keeps paying you for years. CPA pays a fixed fee per qualified depositor, often $50 to $200, paid once. Hybrid splits the difference with a smaller CPA plus a reduced revenue share, usually 10% to 20%. CPA is safer cash flow; revenue share has a higher ceiling if you can attract players who actually bet.
Ask one question before choosing: what happens to my CPA if the player charges back the deposit or gets flagged for bonus abuse? Many programs claw it back. Revenue share rarely has clawbacks, because you were never paid upfront.
The paperwork, tracking, and payout mechanics
Signing up takes minutes. Getting paid correctly takes systems. Every reputable program gives you a unique tracking link or sub-ID structure, and you should never run traffic without one. Sub-IDs let you separate earnings by traffic source, landing page, and campaign, which is the only way to know which content actually converts. If a program cannot give you granular sub-IDs, walk away.
Verification is the part beginners underestimate. You will typically need to provide identity documents, proof of address, and sometimes a company registration depending on your jurisdiction and volume. Payment terms are usually net-30 or net-15, with minimum withdrawal thresholds that range from $50 to $500. Payment methods vary: bank wire, e-wallet payments through services like Skrill or Neteller, and increasingly cryptocurrency. Crypto payouts tend to clear fastest but you carry the price volatility between invoice and receipt.
Licensing matters here too. Operators licensed by Curaçao, which covers a large share of the market including 1Win, generally accept affiliates from a wide range of countries with lighter paperwork. Operators holding UK, Malta, or Swedish licenses impose stricter affiliate compliance, including advertising restrictions and mandatory responsible gambling messaging. Stricter rules mean less flexibility but also less risk of your payment being frozen because a regulator objected to your ad copy.
A pre-signup checklist worth running
Run this before you commit traffic to any program. 1winner offers additional context worth reviewing. It takes an hour and saves months.
- Confirm the commission rate, the exact definition of net revenue, and whether bonuses and jackpot contributions are deducted before or after your cut.
- Check for negative carryover. If it exists, ask whether it resets monthly, quarterly, or never.
- Verify the minimum withdrawal amount, payment schedule, and which payment methods are actually available to affiliates in your country.
- Test the tracking link with a real click and confirm the sub-ID appears in the affiliate dashboard within 24 hours.
- Read the inactivity clause. Some programs zero out your balance if you send no traffic for 60 to 90 days.
- Ask what happens to your players if the operator exits your market or loses its license.
That last point is not theoretical. Market exits happen, and affiliates who did not ask about player migration or balance protection have lost entire books of business overnight.
Where the real money and the real risk sit
Player value varies wildly by product. Sportsbook players referred for betting markets like football and tennis tend to be sharper, bet smaller margins, and produce thinner net revenue. Casino players, particularly those on online casino slots and crash games like Lucky Jet, Rocket X, and Mines, generate higher margins because house edge on those products is larger and play is faster. A player who runs 200 spins an hour on a 96% RTP slot is losing roughly 8% of turnover per hour in expectation. That is why crash game and slots traffic converts to affiliate revenue so much faster than sports traffic.
The competitive field matters for your conversion rates. Programs representing 1Win, MelBet, and BetWinner tend to compete on bonus size and payment flexibility, with 1Win offering a welcome bonus of +500% on deposit, cashback up to 30%, a minimum deposit of 0.5 $, and support for cryptocurrency payments. Against that, bet365 and Pinnacle attract players who care about odds quality and live streaming rather than bonuses, and those players are harder to monetize on revenue share because they bet efficiently. Pinnacle in particular is a sharp book, and sharp players do not lose much.
Traffic source is the other half of the equation. SEO content, comparison pages, and YouTube reviews tend to produce players with longer lifespans. Paid social and push traffic produces volume but higher churn and more bonus abuse. If your program applies a bonus abuse deduction, paid traffic can quietly erode your commission.
Mobile, retention, and the numbers that decide your margin
Mobile share of betting traffic sits above 70% in most markets, so your funnel has to work on a phone. Operators with native Android and iOS apps convert better than mobile-web-only brands because app users bet more frequently and churn less. 1Win ships apps for both platforms, and that matters for affiliates because app installs tend to correlate with higher lifetime value than one-off web registrations. Windows desktop users still exist, mainly for in-play betting with multiple windows open, but they are a shrinking slice.
Retention is where revenue share beats CPA. A player acquired in month one who still bets in month twelve has paid you twelve times. Track your player retention curve at 30, 90, and 180 days. If fewer than 20% of your depositors are still active at 90 days, your traffic is either low quality or your referred brand is failing to retain, and no commission rate fixes that.
Customer service response times matter more than affiliates expect. When a player has a withdrawal problem and cannot reach live chat or phone support, they stop betting, and your revenue stops with them. Test the operator’s support as a player before you promote them. Ten minutes in a live chat queue tells you more than any review page.
Before you sign, model three scenarios: a player who loses $100 a month for a year, a player who breaks even, and a player who wins $2,000 and quits. If the third scenario wipes out your first two under the contract terms, you are not running an affiliate business, you are running a bet on your own traffic. Pick programs with clear net revenue definitions, no punitive negative carryover, reliable monthly payouts, and products where players actually lose at a predictable rate. Then scale the traffic source that produced your best 90-day retention, not the one that produced your biggest first-month deposit.
