iGaming Affiliate Marketing Explained: How It Works in 2025

Affiliate marketing is the engine that powers much of the iGaming discovery ecosystem. Review sites, tipsters, comparison tools, and content creators all participate in affiliate programmes — earning commission when players sign up through their links. Here's everything you need to know about how the system works.

What Is iGaming Affiliate Marketing?

Affiliate marketing is a performance-based marketing arrangement where:

1. An advertiser (the casino) wants to acquire new players
2. A publisher (the affiliate) promotes the casino and sends potential players
3. When a referred player signs up and deposits, the affiliate earns a commission

This model has existed in traditional retail for decades, but iGaming adopted it particularly aggressively in the early 2000s when online marketing was young and casinos needed effective customer acquisition channels.

How Commission Models Work

Revenue Share (RevShare) The most common long-term model. The affiliate earns a percentage (typically 20–45%) of the net revenue generated by referred players for the lifetime of their account.

Example: A player you referred generates £1,000 in net losses over a year. At 30% RevShare, you earn £300.

Cost Per Acquisition (CPA) A one-time payment for each qualifying player sent to the casino. Typical CPA rates for UK players range from £50–£250 depending on the market segment.

Hybrid Models A combination of a lower CPA payment plus a reduced RevShare percentage — offering affiliates upfront income while maintaining long-term revenue participation.

Sub-Affiliate Commissions Large affiliate networks pay a percentage of their sub-affiliates' earnings — incentivising the building of affiliate networks within networks.

The iGaming Affiliate Ecosystem

Affiliate Programmes Every major UK casino operates an affiliate programme, typically managed through a dedicated affiliate manager or outsourced to specialist affiliate networks.

Affiliate Networks Platforms that aggregate multiple casino affiliate programmes — Income Access, Gambling.com, and Affilka are major players. They provide tracking technology, payment processing, and reporting tools.

Affiliate Conferences iGB Affiliate (London and Barcelona) and Sigma are major industry events where affiliates and operators meet, negotiate deals, and discover new partnerships.

How Affiliates Promote Casinos

Affiliates use a wide range of content and marketing approaches:

• Review websites (like CasinoReviewUK): In-depth reviews, comparison tables, bonus guides
• Bonus aggregators: Sites listing all current casino bonuses in one place
• SEO content: Articles targeting searches like "best UK casino" or "Bet365 review"
• YouTube channels: Video reviews, casino gameplay streams, bonus round videos
• Social media: Instagram, TikTok, and X accounts posting casino content (strictly regulated in the UK)
• Email marketing: Newsletter lists built around gambling content
• Tipster and sports betting communities: Community-driven content that includes casino promotions

UK Regulation of iGaming Affiliates

iGaming affiliates marketing to UK players are subject to strict UKGC and ASA (Advertising Standards Authority) regulations:

• All affiliate marketing must be clearly identified as advertising
• No content that appeals to under-18s (no cartoon characters, no youth-oriented celebrities)
• Responsible gambling messaging must be included in all promotional content
• Bonuses must be accurately represented with clear terms
• Affiliates cannot offer bonuses or incentives themselves — only those provided by the licensed operator
• Social media affiliates must label sponsored content per ASA rules

UKGC Affiliate Approval: Casinos must ensure their affiliates comply with these rules. Failure to do so can result in the casino being fined or losing its licence.

What Players Should Know About Affiliate Sites

Understanding the affiliate model helps you use review sites effectively:

• Clearly disclose their affiliate relationships
• Include negative reviews alongside positives
• Show honest ratings — not all casinos rated 9+/10
• Have clear methodology for how they review and rate

• All casinos rated 9.5/10 or higher
• No cons or criticisms mentioned
• No clear authorship or methodology
• Bonus terms not accurately represented

Bonus Terms Must Be Accurate UKGC rules require affiliates to accurately represent bonus terms. If a site shows a bonus without mentioning wagering requirements or key restrictions, that's a red flag.

The Value Exchange

• Players discover casinos through independent review content
• Casinos acquire players cost-effectively without paying for impressions that don't convert
• Affiliates earn sustainable income for producing genuinely useful content

When it works poorly — through undisclosed bias, misleading content, or promotion of unlicensed casinos — it harms players.

At CasinoReviewUK, we are committed to the former. All affiliate relationships are disclosed, our ratings are independent, and we decline partnerships with casinos that don't meet our safety standards.
