What an affiliate actually sells
An affiliate sells introductions. It builds an audience of people who are about to gamble, or might, and it sends them to an operator that pays for the ones who deposit. It does not take a bet, hold a balance or run a game, and in most markets it needs no gambling licence of its own, although in Britain the operator that pays it is responsible for the actions of third parties with whom it contracts and some American states, such as Pennsylvania, require affiliates to be certified or registered. Its assets are an audience, a brand the audience trusts, and the tracked links between the two, and its revenue is whatever operators will pay for the customers those links produce.
That makes it a media business with a performance-based revenue line, and the best way to understand it is as one. The audience is acquired through search, social, video, email, streaming or partnerships. The content is what the audience came for: reviews, comparisons, odds, tips, news, tools, entertainment. The monetisation is the operator's commission. Every affiliate business is some version of this, from a single reviewer with a site in one language to a listed group such as Better Collective, whose brands reported reaching more than 112 million unique users a month in 2025, and the differences are of scale and discipline rather than kind.
This course is written for people who run or want to run an affiliate business, and for the operator-side affiliate managers and investors who need to understand it from the inside. The Affiliate Marketing course on this site covers the channel from the operator's perspective and is a useful companion; this course is the affiliate's own playbook.
The four kinds of affiliate
Comparison and review sites. The classic model: a site ranking operators, reviewing them, listing bonuses, and sending the reader to sign up. Historically the core of the industry and built largely on organic search traffic, which makes it the most exposed to search-engine changes and to regulation, and the model this course spends most of its time on.
Content and media. Sports news, tipsters and picks, odds comparison, podcasts, statistics, community forums. The audience comes for the content, and the affiliate links are one monetisation among several (advertising, subscriptions, data). Slower to build, more defensible, and increasingly where the listed affiliates have moved: Better Collective now describes itself as having evolved from a traditional affiliate business into a diversified digital sports media group, with revenue from subscriptions, sponsorships and advertising alongside revenue share and CPA.
Creators and streamers. An individual with a following on video, streaming or social platforms, promoting operators to it. Fast to scale, persuasive, hard to regulate, and a segment regulators and platforms have moved against: Twitch does not allow links or affiliate codes to sites that contain slots, roulette or dice games, and the UK advertising code bars gambling adverts featuring a person or character who has a strong appeal to those aged under 18.
Performance and paid traffic. Affiliates who buy advertising (where operators cannot, or more efficiently than operators can) and arbitrage the difference between what the traffic costs and what the operator pays. A trading business rather than a media one, with short time horizons and lower margins than publishing, because the advertising is paid for up front: Better Collective's paid media segment reported an EBITDA margin before special items of 24% in 2025, against 30% for the group.
Most successful affiliates are a blend, and the direction of travel across the industry is from the first toward the second: from pages that intercept a search to audiences that come back.
How the money works
Operators pay in three ways, and lesson five is about negotiating them. Here the point is the shape of the revenue.
Cost per acquisition (CPA) pays a one-time fee for each referred customer who meets agreed criteria, such as making a first deposit. Revenue is immediate and predictable and stops the moment the traffic does.
Revenue share pays a percentage of the net revenue the referred customers generate for as long as they play. Revenue is deferred, grows as the base of referred customers accumulates, and continues after the traffic that produced it. A mature revenue-share book is an annuity, and it is the reason affiliate businesses sell for multiples of their earnings.
Hybrid pays some of each.
An affiliate's income statement has one revenue line, split by operator and model, and a cost base that is mostly people (content, SEO, product, compliance) and acquisition (paid traffic, if used, and the cost of building sites). Margins at scale are high, 30% at EBITDA level before special items for Better Collective in 2025, which is what attracted the capital that built the listed affiliates, and volatile, which is what that capital has learned since.
What changed: the reset
Between 2024 and 2026 the affiliate industry went through what this course calls a reset, and anyone entering it should understand the three forces that drove it.
Search. Google's core updates and its enforcement, from May 2024, against "site reputation abuse" (third-party pages published on an established site to take advantage of its ranking signals; Google's own examples include a third-party "best casinos" page on a medical site) removed traffic from thin comparison content and from affiliate sections hosted on news sites. Google has since renamed it the site reputation policy and, for searches in the European Economic Area, ranks such pages separately from the host domain instead of applying a manual action. Established affiliates were exposed too: Better Collective cited significant changes in the media partnership landscape following Google policy updates among the pressures of 2025, and now lists AI-driven search features as a risk to the traffic it receives from search engines. The iGaming SEO course covers the mechanics; the lesson for a business is that traffic acquired through a single channel is a single point of failure.
Regulation. Markets regulated, and regulation reached affiliates: licensing in American states, operator liability for affiliate conduct in Britain and Europe, advertising restrictions that cut what an affiliate page may say, and, most consequentially, restrictions on bonuses. Brazil's regulated market, which opened on 1 January 2025, prohibited operators from granting any bonus, advance or prior advantage for placing a bet (Law 14.790/2023, article 29), which removed the sign-up bonuses that drive affiliate conversion. Better Collective reported that its Brazilian revenue fell from €73m in 2024 to €49m in 2025, with lower revenue-share income, and that the ban on welcome bonuses had redirected part of new player activity to offshore sportsbooks. The Affiliate Compliance and Licensing course is the full treatment.
Operator behaviour. Operators became stricter about the affiliates they would work with, because regulators hold them responsible for what those affiliates do. Commercial terms shifted too, though not in one direction: Better Collective has moved its North American business away from upfront payments toward revenue share since 2022, while in 2025 the CPA revenue of its paid media segment rose by 16%. The days of operators competing for any traffic at any price ended in the regulated markets.
The affiliates that came through were the ones with diversified traffic, a real audience, compliance built in, and revenue-share books that kept paying while new acquisition fell. The ones that did not were built on a search ranking and a bonus.
The economics of a site
A single affiliate site's economics can be sketched on one page and should be, before any content is written.
Traffic: the visits the site can realistically attract in its market, by channel, within a year and within three.
Conversion: the share of visits that click an operator link, the share of clicks that register, the share of registrations that deposit. Each is measurable and each varies by market, vertical and page type; a comparison page converts far better than a news article.
Value: what an operator will pay per depositor (CPA) or what a depositor is worth over time (for revenue share: average net revenue per customer per month, times the share, times the expected lifetime).
Cost: content, technology, SEO, compliance, licensing where required, and the founder's time.
Multiply the first three, subtract the fourth, and the result is whether the site is a business. Many are not, which is why so many affiliate sites are abandoned, and why the ones that survive are run by people who did the arithmetic first.
What this course covers
Lesson two is markets and verticals: where to compete and when. Lesson three is building the asset: brand, site, content operations and the standards that survive updates and regulators. Lesson four is traffic beyond search, because search alone is no longer enough. Lesson five is deals: the structures, the traps and the negotiation. Lesson six is data: tracking, reconciliation, forecasting and fraud. Lesson seven is growth, valuation and exit.
The through-line is that the affiliate business is a media business that has long been paid as a performance channel, and that its future belongs to the affiliates who build it as the former while being measured as the latter.
