iGaming

iGaming is the affiliate trade name for real-money gambling sold online: online casino (slots, table games, live dealer games), sports betting, and poker. Affiliates send players to licensed operators and are paid either a fixed amount when a referred player makes a first deposit, or a share of the revenue that player generates over time.

What sets iGaming apart from a vertical like nutra is that the product itself is licensed, country by country. An operator may only take players from markets where it holds a licence or where the law allows it, and the affiliate inherits those limits. In the UK the regulator is the Gambling Commission; in Malta the Malta Gaming Authority issues a B2C licence "to offer or carry out a gaming service" (as of October 2026); Curaçao moved to a new regime under the National Ordinance on Games of Chance (LOK), with the Curaçao Gaming Authority now describing itself as "the regulator for the online gaming industry" and publishing a public licence register (as of October 2026).

The United States is a patchwork. According to the American Gaming Association's State of the States 2026 (May 2026), at the close of 2025 online casino was legal in eight states (seven with a full range of games, Nevada with online poker only), while legal sports betting was offered in 39 states plus the District of Columbia.

The honest summary: iGaming pays well and rewards long-term traffic, but it is a regulated product. Licensing, age limits, responsible gambling and advertising codes are part of the job, not an afterthought.

Three groups share the money. Operators run the casino or sportsbook under a licence and earn the house edge or betting margin. Affiliate programmes, either run in-house by the operator or by a company that manages several brands, recruit and pay affiliates. Affiliates own the traffic: review and comparison sites, content creators, media buyers.

Follow one player through the chain. A person reads a comparison page, clicks to an operator, registers, verifies their age and identity, and makes a first deposit. That event is the FTD (first-time depositor) and it is the unit most deals are built around. From then on, the operator measures the player's GGR (gross gaming revenue: stakes minus winnings) and then NGR (net gaming revenue), which is GGR after deductions such as bonuses, payment fees and gaming taxes. Which deductions apply is set by each programme; Blask notes that NGR deductions are "programme-specific" (updated 11 September 2026).

Two business shapes dominate on the affiliate side:

• SEO and content affiliates build review sites, bonus comparison pages and betting guides that rank in organic search. Their cost is content, links and time; their reward is traffic that keeps arriving for years, which suits revenue share. The discipline behind this is affiliate SEO.
• Paid media affiliates buy traffic on pop, push, native or social platforms and need to recover ad spend quickly, which pushes them toward CPA deals.

Responsibility does not stop at the operator. The UK Gambling Commission states that under its social responsibility code 1.1.2, "Licensees are responsible for the actions of third parties with whom they contract" (1 July 2019). In practice, that means a UK-licensed operator will audit what its affiliates publish and can terminate them for non-compliant marketing.

The legal market also competes with an illegal one. The AGA estimates that illegal operators take $53.9 billion a year from American players (May 2026). Promoting unlicensed operators into a market where they are not allowed is the fastest way to lose a programme, a payment provider and, in some countries, much more.

iGaming deals come in a handful of shapes. PropellerAds' guide to iGaming affiliation (13 July 2024) lists RevShare, CPA, Hybrid, CPL and CPI; the first three cover most of the money.

CPA per FTD. A fixed payout when a referred player makes a qualifying first deposit. Programmes usually attach a baseline: a minimum deposit, and sometimes a minimum amount wagered, that the player must reach before the CPA counts. Baselines differ per deal and per country, so read them in the contract rather than assuming.

Revenue share. A percentage of the NGR the player generates for as long as the deal runs, often for the player's lifetime. It rewards traffic that brings loyal players and punishes traffic that brings bonus hunters.

Hybrid. A reduced CPA plus a reduced revenue share. PropellerAds describes it as "a reduced CPA payment ... with a reduced RevShare percentage".

CPL and CPI. Paid per registration or per app install. Less common and usually tightly capped.

For orientation only, the affiliate platform vendor Track360 published benchmarks drawn from its own platform data for Q3 2025 to Q2 2026 (Track360, 18 July 2026). The vendor says Tier 1 casino CPA runs "$150-$400 per FTD; median $250", sportsbook CPA "$120-$350 per FTD; median $200", casino revenue share "25-45% of NGR; median 30%", sportsbook revenue share "20-35% NGR", and hybrid deals "$75-$150 CPA + 15-25% RevShare". That is one vendor's sample, not the market.

Negative carryover decides how revenue share behaves when players win. With carryover, a negative month is "set against future earnings before any payment is made"; with no negative carryover (NNCO), the balance resets to zero each period. One big winner can wipe out months of earnings under carryover, so this clause matters as much as the percentage.

A worked example with illustrative numbers. An affiliate refers 40 FTDs in a month. On a $200 CPA, that is $8,000 now. On 30% revenue share, if those players generate $350 NGR each over their first year, that is $4,200 in year one, with more if they stay active, and less if one high roller wins big under negative carryover. Paid media buyers usually need the CPA; site owners with free organic traffic can afford to wait.

An iGaming "offer" is an operator brand plus a deal plus a set of allowed countries. The products behind it differ in ways that change the traffic you need.

• Online casino. Slots, table games and live dealer games. Revenue is driven by the house edge across many small bets, so player value builds over time and suits revenue share.
• Sports betting. Revenue is seasonal and event driven (major tournaments, weekends) and margins swing with results. Deals are often slightly lower than casino in the vendor benchmarks above.
• Poker. Players play against each other and the operator takes a rake, so revenue is steadier but the audience is smaller.
• Social casino and sweepstakes. Products played without real-money gambling, or with prizes under sweepstakes rules. Platforms treat them separately: Google certifies an account for either online gambling or social casino games, not both (as of October 2026).

Bonuses are part of the offer, and regulators are tightening them. In Great Britain, the Gambling Commission capped wagering requirements at 10 times and banned promotions that mix "two or more types of gambling, such as betting and playing slots", with all changes in force from 19 January 2026 (updated 24 July 2025). An affiliate page that still shows old UK bonus terms is not just stale, it is a compliance problem for the operator that pays it.

Traffic in iGaming splits into organic content and paid media, and the platform rules are stricter than in most verticals.

Organic search is the backbone of casino affiliation: review sites, "best casinos in [country]" comparison pages, bonus explainers, betting guides. It is slow to build and competitive, but the traffic arrives without per-click cost and matches the revenue share model. The rules of the game are Google's spam policies, covered on affiliate SEO.

Pop ads are the cheapest paid volume and gambling campaigns run on pop networks such as Adsterra and PropellerAds. PropellerAds even publishes its own guide to iGaming affiliation (13 July 2024). The trade-off is low intent and bot traffic, so pop works best for broad casino offers on CPA with tight fraud filtering. Push and native sit in the middle: more context than pop, cheaper than social. Each network sets its own gambling rules and allowed countries, so check the advertiser policy of RichAds, MGID or any other network before launch.

Google Ads allows gambling ads only after the advertiser applies for certification. Google lists 70+ countries with their own licensing requirements, requires that ads "never target minors", and requires landing pages to show "an age warning, addiction resources, terms and conditions and a footer containing the licensee name, license number and a privacy policy" (as of October 2026). Comparison and aggregator sites can be certified, but "must not offer gambling services themselves or link to gambling services they own".

Facebook works the same way. Meta says online gambling ads "are only allowed once an ad account has obtained authorization", that ads may not target people under 18 nor unsupported gambling markets, and that ads for aggregator or affiliate sites also need authorization, requested through Meta Business Suite with licence evidence (policy page last changed 18 May 2026). Without authorization, gambling ads on Meta are simply not allowed.

Cloaking, showing reviewers one page and users another, is banned by every major platform and by Google Search. It is named here only so it is clear that it is outside what this site covers.

Two funnel shapes cover most iGaming traffic.

Content funnel. Search query, then a review or comparison page, then a click to the operator's registration page. The page earns the click by being useful: licence details, payment methods, withdrawal times, bonus terms in plain words, responsible gambling information. Commercial links are marked with rel="sponsored", which Google describes as the value for "advertisements or paid placements" (last updated 10 December 2025).

Paid funnel. Ad, then an optional pre-lander (a short bonus explainer, a sport event preview), then the operator. Pre-landers carry the same obligations as the operator's own pages where platforms require it: on Google, the landing page must display age warnings, addiction resources and licensee details as described above.

Between the click and the payout sit steps the affiliate does not control: registration, age and identity verification, the first deposit and, for CPA, the baseline. Each step loses players, so a funnel that looks healthy at click level can still produce few qualifying FTDs.

Free-to-play demo games deserve a specific note. The UK Gambling Commission requires free-to-play games offered through affiliates in Great Britain to be "only played by customers whose age has been verified" (1 July 2019), so open demo slots on a UK-facing affiliate site are a known compliance trap.

Tracking in iGaming has two layers that rarely agree perfectly.

The first is your own: a tracker such as Keitaro, Binom, Voluum or RedTrack (see affiliate trackers) records each click and passes a click ID to the programme. The programme sends postbacks back for registration and FTD, so you can see cost per FTD per source, placement and creative. The general mechanics are on tracking and attribution.

The second layer is the programme's reporting, which is the only source of truth for revenue share: NGR per player, deductions and carryover are calculated on the operator side and are usually reported monthly. You cannot reproduce NGR from your own data, which is why many affiliates treat revenue share reports as something to reconcile, not just read.

What to watch:

• Click to registration and registration to FTD per source, to find where players drop.
• Qualified FTDs versus raw FTDs, since baselines remove some depositors from CPA.
• NGR per FTD by cohort month, which shows whether a source brings players who stay.
• Discrepancies between tracker FTDs and programme FTDs. Some gap is normal, because postbacks fail, timezones differ and programmes apply their own qualification rules. Track the gap per source and per month; a sudden change is the signal to raise it with the affiliate manager, with click IDs and timestamps ready.

A working iGaming affiliate stack depends on which side of the business you are on.

For content sites:

• SEO tools for keyword research, backlink analysis, rank tracking and audits: Ahrefs, Semrush and Moz Pro, grouped under SEO tools.
• A content management system with clean templates for reviews and comparison tables, and a process for updating bonus terms when operators change them.
• Licence checks. Before listing an operator, check its licence in the regulator's register, for example the Curaçao Gaming Authority register or the register of the authority named in the operator's footer.

For paid media:

• A tracker from affiliate trackers, to connect spend to FTDs per placement.
• Ad networks that accept gambling, from ad networks: pop and push networks such as Adsterra, PropellerAds and RichAds, native networks such as MGID, each with its own country and licence rules.
• Spy tools from spy tools, such as AdPlexity and Anstrex, to see which formats and angles already run in a market.
• Landing page builders from landing page builders for pre-landers, with room for the age and responsible gambling elements platforms require.

Programmes and networks. Many affiliates work directly with operator programmes; others go through CPA networks that aggregate gambling offers. Direct deals usually give more control over terms such as carryover; networks give access to more brands with one payment relationship.

Compliance is the operational core of iGaming affiliation, because the operator's licence is at stake and the operator will pass that pressure down.

Advertising codes. In the UK, the CAP Code section 16 says gambling marketing "must be socially responsible", must not have "strong appeal to children or young persons, especially by reflecting or being associated with youth culture" (16.3.12), and that "No-one who is, or seems to be, under 25 years old may be featured gambling or playing a significant role" (16.3.14). The ASA states that these rules cover marketing by third parties, including affiliate marketers (as of October 2026).

Age and responsible gambling. Every platform rule above forbids targeting minors, and Google requires age warnings and addiction resources on landing pages. Minimum ages are set by each jurisdiction, so the page for each market should state the right one and link to local help resources.

Market by market licensing. Keep a list of which operator is licensed where, and only send traffic from those markets. In the US, each of the eight online casino states runs its own licensing system, and obligations for affiliates themselves vary by state. Check the state regulator's rules for affiliates before sending traffic to any state.

Disclosure. Mark commercial links as sponsored and say clearly that the site earns commission from operators.

Three recurring workflows keep an iGaming affiliate business healthy.

1. Operator vetting before listing.

1. Read the footer: licensee name, licence number, regulator.
2. Look the licence up in the regulator's own register, not on the operator's site.
3. Check which countries the licence and the programme allow, and block the rest in your tracker or geo settings.
4. Read the deal: CPA amount, baseline, revenue share percentage, which NGR deductions apply, whether negative carryover applies, and how disputes are handled.
5. Record all of it with the date, so you can tell later what changed.

2. Content refresh for review sites.

1. Keep a list of every page that mentions a bonus, wagering requirement or payment method.
2. Recheck those terms against the operator's site on a schedule and whenever a regulator changes rules, as the UK did with the wagering cap that came into force on 19 January 2026.
3. Update the page, note the date of the check on the page, and remove operators that lose their licence or leave a market.

3. Paid campaign launch.

1. Confirm the platform allows gambling in the target country and that the account has the certification or authorization the platform requires (Google certification, Meta authorization).
2. Build the pre-lander with age warnings, responsible gambling links and terms.
3. Launch on a small budget with postbacks for registration and FTD, and judge sources on cost per qualified FTD, not cost per click.
4. Scale only sources whose players show NGR after the first weeks; pause placements with abnormal click patterns that suggest bots.

Revenue share value builds up as players keep playing, so judge sources by cohort month rather than by the first days of data. Set review dates before launch, so a slow start is not cut too early and a losing source is not kept on hope.

• Negative carryover on revenue share. A single high roller who wins can erase months of commission. Negotiate NNCO where possible or price the risk in.
• Baselines you did not read. A CPA deal with a high baseline can pay far fewer FTDs than you counted.
• Unlicensed operators and wrong markets. Sending players to an operator not licensed in their country risks your programme, your payment processor and, in some jurisdictions, legal liability.
• Stale bonus terms. Old offers on a page can breach advertising rules for the operator, who is responsible for its affiliates under UK rules.
• Platform bans. Running gambling ads without Google certification or Meta authorization, or with cloaked landing pages, ends in account bans. There is no compliant shortcut.
• Bot traffic on cheap sources. Pop and some push inventory bring registrations that never deposit. Judge on qualified FTDs.
• Youth appeal in creatives. Cartoon styles, young-looking people and youth culture references break UK rules even when the target age is correct.
