Definition
Affiliate marketing is a performance-based model in which independent partners — affiliates — promote a company's products and are paid only for the measurable results they deliver, most commonly tracked through unique links and server-to-server callbacks. The company sets what counts as a result (a registration, a first deposit, a sale, ongoing revenue) and the rate, and the affiliate decides how to generate that result: content and SEO, paid media, email, social, streaming, apps or communities.
Because payment is tied to outcomes, the company shifts acquisition risk and upfront cost onto partners and can scale the channel without a fixed marketing headcount.
In iGaming, affiliate marketing is one of the two primary player-acquisition channels alongside direct in-house media buying, and for many operators it is the larger of the two. It is well suited to gambling because affiliates can reach places and audiences a licensed brand cannot address directly — restricted ad platforms, long-tail GEOs, niche communities — and because the RevShare option lets partners and operators share the long-term value of a player rather than arguing about a fixed acquisition price.
In context
Commission is paid under one of three models. RevShare gives the affiliate a percentage of the net revenue the referred players generate, for as long as the deal runs; it aligns both sides with player value but pays slowly and varies with luck.
CPA pays a fixed sum per qualifying action, giving the affiliate predictable cash flow and moving variance to the advertiser. Hybrid combines a smaller fixed amount with a smaller revenue share.
Affiliate types range from SEO content and comparison sites, through streamers and social creators, to professional media-buying teams, each with different economics and risk profiles.
Running the channel well requires tracking integrity (links, cookies, click IDs and postbacks that agree with each other), fraud controls (deduplication, geo checks, bonus-abuse detection, clawbacks), and clear written terms so disputes have a reference point. Done poorly — opaque terms, unreliable tracking, tolerance of fraud — the channel fills with low-quality volume and good affiliates leave.
Done well, it becomes an operator's most efficient and durable source of players.
Worked example
An operator's attribution shows that 45% of new depositing players in a quarter came through its affiliate programme, split roughly 60/40 between SEO and comparison partners on RevShare and media-buying teams on CPA. The SEO partners cost less per player and retain better; the media teams deliver faster at launch and in new GEOs.
