Affiliate marketing in iGaming, explained

Affiliate marketing is one of the oldest and most important customer-acquisition channels in online gambling. A large share of the players operators sign up arrive through affiliates — independent publishers who send traffic to operators in exchange for commission. This explainer sets out how the model works, how affiliates are paid, and the software that makes the whole system run.

What an affiliate is

An iGaming affiliate is a third-party marketer that promotes operators to potential players and earns a commission when that promotion produces business. Affiliates range from large comparison and review websites that rank operators, to content publishers, to social and streaming personalities. What they share is a performance-based relationship: they are paid for results, not for running an ad.

The appeal to operators is that affiliates shift acquisition cost from fixed to variable. Instead of paying upfront for advertising that may or may not convert, an operator pays an affiliate only when a real player is delivered — aligning the marketer’s incentive with the operator’s.

The three commission models

Affiliate deals are built on three commission structures, often combined:

• Revenue share: the affiliate earns an ongoing percentage of the net revenue the players they refer generate for the operator. This rewards affiliates for sending high-value, long-term customers, since they keep earning as those players play.
• CPA (Cost Per Acquisition): the affiliate earns a fixed one-off payment for each player who signs up and meets a qualifying condition, such as a first deposit. CPA gives the affiliate certainty and the operator a known acquisition cost.
• Hybrid: a combination of a smaller CPA plus a reduced revenue share — the most common arrangement for established affiliates, balancing upfront payment with long-term upside.

The choice of model shapes behaviour. Revenue share attracts affiliates confident in the quality of the players they send; CPA suits those who want to be paid immediately; hybrids split the difference.

The listed affiliate businesses

Affiliation has grown into a substantial industry with its own public companies. Better Collective, Gambling.com Group, Catena Media, Raketech and Gentoo Media are all listed affiliate businesses, running portfolios of comparison and content sites that rank in search and funnel players to operators. Their scale demonstrates how valuable organic acquisition has become — and how much operators are willing to pay for it.

These businesses live and die by search visibility and the quality of the traffic they send, which is why they invest heavily in content and are acutely exposed to changes in search algorithms and gambling-advertising rules.

The software that runs it

Behind every affiliate programme is tracking and management software that attributes each sign-up to the right affiliate and calculates commission. This is a distinct supplier category. Income Access (owned by Paysafe) is a long-established affiliate-tracking and network platform; MyAffiliates and NetRefer have served tier-one operators for years; Affilka by SOFTSWISS and PartnerMatrix (part of EveryMatrix) are built inside larger platform ecosystems; and newer entrants such as Scaleo, RavenTrack and Cellxpert compete on analytics and ease of use. Aggregation dashboards such as Voonix help affiliates themselves track earnings across many programmes.

The software matters because trust runs both ways: affiliates need to know they are being credited and paid accurately, and operators need to know they are not paying for fraudulent or low-quality traffic. Reliable tracking is the foundation of the whole relationship.

Why it endures

Despite tighter advertising rules and periodic search-algorithm upheavals, affiliate marketing remains central to iGaming because its core logic is sound: performance-based, variable-cost acquisition that aligns marketer and operator. As other channels face rising costs and regulatory limits, the affiliate model’s efficiency keeps it indispensable — and keeps its software an essential part of the supplier stack.
