Affiliate marketing has served as the invisible engine of the online gambling industry since its inception. Few sectors confront advertising restrictions as severe as gambling, and that reality has made operators dependent on third parties to drive traffic to gambling sites — a task they often struggle to accomplish on their own. Over the years, this dependence has turned affiliates into a structural pillar of the sector's customer acquisition.

The mechanics appear simple. An affiliate receives a tracking link from an operator, attaches it to a button or banner, and earns a share of the wagering activity generated by every registration logged through it. In practice, however, the field conceals considerable complexity, beginning with the payout models in use, volume thresholds, and key performance indicators. Affiliate programs — and the way they operate on both the operator and partner sides — have evolved substantially over the past decade, as have the tools and criteria used to run them.

To explain how these programs function and how today's landscape compares with where the industry began, CoinCentral spoke with Sebastian Jarosch, founder of Mithrillium Media Ltd. Jarosch previously served as Head of Affiliates at Betsson Group and is a prominent figure in gambling marketing. He serves as a judge for the SBC Europe Awards and has been interviewed by iGaming industry outlets including iGB, EGR, and SiGMA. His commentary covers how the affiliate arena operates, what works, and what does not.

How Casino Affiliate Programs Work — and Why They Matter

Casino affiliate programs enable publishers and media companies to earn commissions by referring new players to gambling operators through traffic sources such as SEO, PPC, social media, and email. Jarosch described affiliates as one of the most important acquisition channels available to gambling operators: because they are paid based on performance, they allow operators to gain visibility quickly.

How Affiliate Websites Earn From Referrals

Affiliates promote casino operators through top lists, reviews, comparisons, guides, and educational content that contains tracking links. When a player clicks a link, registers an account, and makes a deposit, the affiliate earns either a CPA payment, a revenue share, or a mix of both.

CPA, Revenue Share, and Hybrid Commission Models

The three dominant commission structures differ in how they compensate partners. CPA deals offer a fixed payment for each new depositing customer. Revenue-share deals pay affiliates a predetermined percentage of the net gaming revenue generated by the players they refer. Hybrid agreements combine both approaches, paying a smaller CPA together with a revenue share. The model chosen shapes the economics on both sides: under CPA the operator pays a known amount per depositing customer, while under revenue share the affiliate's earnings rise and fall with the ongoing activity of the players they send.

How Casinos Track Referrals and Calculate Commissions

Affiliate programs use tracking links, referral codes, and unique affiliate identifiers to attribute sign-ups and deposits to individual partners. Commissions are then calculated according to the agreed remuneration model, with revenue-share payments typically based on net gaming revenue after deductions such as bonus costs and admin fees. Because payouts flow directly from this attribution, accurate tracking underpins every commission an affiliate earns.

What Makes an Affiliate Program Attractive to Publishers

Competitive programs offer more than attractive commission rates, according to Jarosch. The strongest stand out with reliable payments, transparent reporting, high conversion rates, and trustworthy brands with strong retention rates. Responsive account managers, fair terms, lifetime commissions, and low admin fees also rank among the factors affiliates weigh most heavily. Since revenue-share income is calculated after deductions, terms such as low admin fees and lifetime commissions can materially affect what each referred player is ultimately worth to a partner.

How Review and Comparison Sites Guide Players

Player-centric review sites such as Casino-Groups evaluate online casinos based on factors including licensing, reliability, game selection, bonus offers, payment methods, withdrawal conditions, and customer service. These sites educate players, compare operators, highlight pros and cons, and help users find the casino that best matches their preferences. Because reviews and comparisons are among the content formats affiliates use to carry tracking links, readers can weigh how a site is compensated when evaluating its recommendations.

The Biggest Challenges in Competitive Markets

Competition for high-volume keywords is intense, particularly in valuable gambling markets dominated by large affiliate companies. Rising SEO costs, AI-generated content, search engine algorithm updates, regulatory restrictions, and parasite SEO are all making player acquisition increasingly difficult, Jarosch said.

How Regulation Shapes Casino Affiliate Marketing

Regulations determine which traffic sources, messaging, and markets affiliates can legally target. Changes to compliance requirements, advertising restrictions, or affiliate-specific guidelines can significantly affect traffic volumes, conversion rates, and revenue — at times rendering entire markets commercially unattractive.

Common Mistakes Made by Newcomers

Newcomers often underestimate their competition and expect quick results from generic casino reviews, Jarosch noted. They tend to prioritize affiliate deals over the fundamentals that build durable businesses: player intent, SEO, trust, content quality, compliance, and brand awareness.

How Affiliate Programs Are Expected to Evolve

Looking ahead, Jarosch expects more markets to become regulated, bringing stricter compliance requirements and tougher competition. Organic traffic is becoming less profitable as players increasingly turn to AI tools for discovery, and affiliates will need to concentrate on brand recognition, traffic diversification, high-quality content, and stronger long-term relationships to remain competitive.
