iGaming Affiliate Marketing Explained: CPA, Revenue Share and Hybrid Deals

iGaming affiliate marketing is a commercial arrangement in which a publisher or marketing partner introduces customers to a gambling operator and earns commission under an agreed contract. Common payment models are cost per acquisition (CPA), revenue share and a hybrid combining both.

The attractive headline rate is only part of the offer. Qualification rules, revenue deductions, attribution, negative carryover and compliance obligations determine what the arrangement is actually worth.

This guide explains those mechanics for industry readers and publishers, using hypothetical calculations rather than promised earnings.

What does an iGaming affiliate do?

An affiliate helps an operator reach potential customers. Within the iGaming industry, its channels can include comparison websites, editorial guides, approved advertising and other permitted promotional activity.

The affiliate normally does not accept the customer’s bets or manage the gambling account. The operator provides the gambling service.

Gambling.com Group’s 2025 annual report provides a documented example of this business model. It describes performance-marketing arrangements using CPA, revenue share and hybrid commission.

That distinction matters when evaluating a business: an affiliate’s commission revenue is not the same as the operator’s gaming revenue, and neither figure automatically represents profit.

How the referral journey works

A typical referral arrangement uses a link or another identifier to attribute activity to a partner.

An illustrative journey is:

1. A visitor reads the affiliate’s content.
2. The visitor follows a tracked link to the operator.
3. The visitor registers and completes any required verification.
4. The visitor meets the agreement’s qualifying conditions.
5. The operator records the attribution and applicable commission.
6. The affiliate receives payment under the settlement terms.

The exact rules vary. Registration alone may not qualify for a CPA payment, and a deposit alone may not satisfy every condition.

An operator may also reject duplicates, prohibited traffic or activity that does not comply with the agreement. The reporting system should make those distinctions visible enough for the affiliate to understand its results.

CPA: cost per acquisition

CPA provides an agreed payment for each qualifying acquisition.

In gambling affiliate programmes, qualification commonly involves more than a click. The agreement might require a new customer, a qualifying deposit, permitted geography and other conditions.

For a hypothetical example:

• Qualifying acquisitions: 40
• CPA per acquisition: £100
• Gross affiliate commission: 40 × £100 = £4,000

If only 32 referrals satisfy the conditions, the commission at that rate is £3,200 instead.

These figures are teaching examples, not typical rates or a forecast of earnings.

CPA can make short-term forecasting simpler once qualification and rejection rates are understood. However, it does not automatically make a campaign profitable. The affiliate must account for its own costs and any later contractual reversals.

A £100 payment is less useful if acquiring each qualifying customer costs more than £100.

Revenue share

Revenue share pays a percentage of the revenue defined in the agreement for attributed customers.

The commission base may be described as net gaming revenue, net revenue or another programme-specific term. Those labels do not guarantee identical deductions.

For a hypothetical month:

• Attributed starting gaming revenue: £20,000
• Agreed deductions: £5,000
• Commission base: £15,000
• Revenue share: 25%
• Affiliate commission: £3,750

Revenue share can produce income after the initial referral, subject to the contract and customer activity. It can also fluctuate substantially.

The phrase “lifetime revenue share” needs careful reading. Establish how the agreement defines that commitment, what happens after termination and whether inactivity or other conditions affect payment rights.

Do not treat it as a guarantee of permanent income.

Hybrid commission

A hybrid arrangement combines an acquisition payment with a revenue share.

For example, suppose an agreement pays:

• £50 for each qualifying acquisition.
• 15% of a defined revenue base.

With 40 qualifying acquisitions and £15,000 in commissionable net revenue, the illustrative result is:

(40 × £50) + (£15,000 × 15%) = £4,250

That does not prove hybrid is better than CPA or revenue share. Different programmes can have different customer cohorts, deductions, qualification conditions and payment restrictions.

Hybrid can balance earlier cash receipts with ongoing participation in revenue, but the value still depends on the complete terms.

Which payment model is best?

There is no universal answer.

CPA can suit an affiliate that values earlier, more predictable receipts and understands its cost per qualifying acquisition.

Revenue share can suit a business able to tolerate variable income and evaluate the long-term results of attributed cohorts.

Hybrid can provide a combination, but the two components must be assessed together.

Compare offers using the same hypothetical customer cohort and period. Estimate qualification, commissionable revenue, contractual adjustments and your own costs.

An offer with a higher CPA may have stricter qualification rules. A higher revenue-share percentage may apply to a smaller net amount. A hybrid can look generous while producing modest income after deductions.

The correct comparison is expected net business contribution under realistic assumptions, not the largest number on the programme homepage.

NGR deductions: the part publishers must understand

An affiliate agreement can permit deductions for specified bonuses, duties, fees or other adjustments.

Ask for the exact definition, not a general explanation from a sales presentation.

Suppose two hypothetical programmes each attribute £20,000 in starting revenue to an affiliate.

• Programme A deducts £4,000 and pays 25%: £4,000 commission.
• Programme B deducts £9,000 and pays 30%: £3,300 commission.

The higher percentage pays less in this example.

Other terms can also matter: minimum payment thresholds, currency conversion, administrative charges and the right to revise conditions.

The Entain Partners agreement is one publicly available example of detailed programme terms. Read the agreement applicable to your particular market and relationship rather than assuming a public headline describes every arrangement.

Negative carryover

Revenue-share calculations can become negative during a period. Player winnings and the permitted adjustments can exceed the relevant starting revenue.

A negative-carryover clause determines whether that deficit reduces commission in a later period.

Consider a hypothetical agreement with a £1,000 carried deficit followed by £3,000 of positive commissionable revenue. If the contract offsets the full deficit before applying a 25% share, the resulting commission is £500.

Without that offset, 25% of £3,000 would be £750.

Real programmes can apply different rules, including cohort-level treatment or special clauses for large wins. Ask whether a reset applies automatically and whether exceptions exist.

A statement that a programme offers no negative carryover should be checked against the actual agreement and any market-specific terms.

Tracking and attribution

Tracking establishes which partner receives credit. It is not merely a technical detail: inaccurate or misunderstood attribution changes the commercial result.

Review:

• The attribution window and starting event.
• Whether the arrangement uses first-click, last-click or another rule.
• How registrations and deposits are connected.
• How duplicate customers and existing accounts are treated.
• Whether cross-device activity is supported.
• How consent choices and browser restrictions affect measurement.
• How discrepancies can be investigated.

Use distinct campaign identifiers where supported, so different placements can be evaluated separately.

Avoid putting personal customer information into tracking URLs. The operator’s approved tools should be used within the applicable privacy and contractual requirements.

A high click count with few qualifying acquisitions is a signal to investigate the journey. It is not proof that the traffic is valuable or that reporting is wrong.

What to measure beyond clicks

A useful reporting view follows the whole funnel.

Clicks: how often visitors follow the referral route.

Registrations: how many attributed accounts are created.

Qualifying acquisitions: how many satisfy the commission conditions.

Approval rate: what share of submitted acquisitions becomes payable.

Commission: the amount earned after contractual calculations.

Business contribution: commission minus the affiliate’s relevant operating and acquisition costs.

For example, a hypothetical campaign spends £1,500 and produces £2,400 of approved commission. Its contribution before other costs is £900.

If editorial production and allocated staffing cost another £1,100, the same campaign is not profitable on that broader cost basis.

Use consistent periods. Revenue share can arrive over time, so comparing one month’s campaign spending with a later cohort’s total receipts can misrepresent performance.

Compliance in Great Britain

Affiliate marketing sits within gambling advertising and wider marketing rules. Commercial partners must establish which requirements apply to their activity and target audience.

The Gambling Commission’s guidance on affiliates and third parties explains operator responsibility in affiliate direct marketing, including risks involving self-excluded customers.

CAP’s gambling advertising rules address socially responsible advertising and protections for children and vulnerable people. They prohibit, among other things, presenting gambling as a solution to financial problems.

Marketing approvals, audience selection and suppression processes need to work in practice. A contract clause alone does not demonstrate that a campaign follows the rules.

Other jurisdictions can require different licences, registrations or advertising controls. Great Britain’s framework should not be presented as a global rulebook.

Advertising disclosure and editorial independence

Readers should be able to recognise commercial content before they engage with it.

The ASA’s online affiliate marketing guidance explains when affiliate content falls within advertising rules and how its commercial nature should be identifiable.

For a publisher, useful practices include a clear disclosure near relevant content, accurate offer descriptions and an explanation of how comparisons are produced.

Do not claim to have tested a casino if the review is based only on public information. Distinguish a documented feature from a first-hand assessment.

If rankings are affected by commercial relationships, the reader should not be left with a misleading impression of independent selection. A disclosure should explain the relationship plainly rather than rely on vague wording.

Email, SMS and personal data

Direct marketing introduces additional rules beyond the affiliate programme agreement.

The ICO’s electronic mail marketing guidance explains the PECR framework, including consent and the limited circumstances in which a soft opt-in can apply.

For unsolicited messages to individual subscribers, a publicly visible email address is not automatically consent. Nor does a list described as containing “interested players” establish a lawful basis for sending promotions.

Gambling-specific controls and operator restrictions must also be considered. Verify approvals, suppression arrangements and opt-out handling before using a channel.

The rules for individual and corporate subscribers differ, so identify the audience accurately. A campaign being commercially attractive does not remove those distinctions.

Building an affiliate publishing business

Begin with a defined audience and a manageable market.

A publisher should be able to explain the subject accurately, maintain its content and understand the agreements behind its commercial recommendations.

A practical sequence is:

1. Choose the audience, product focus and relevant jurisdiction.
2. Establish the permissions and advertising obligations for that work.
3. Compare programme contracts using consistent assumptions.
4. Build useful content and a clear comparison methodology.
5. Test permitted tracking without creating deceptive or prohibited activity.
6. Monitor approved acquisitions, commissions and content accuracy.
7. Diversify traffic and commercial relationships where practical.

Organic search can be a channel, but it is not a guaranteed source of customers. A business plan should consider what happens if traffic falls, a partner changes terms or a market restricts promotion.

The objective is a viable publishing operation with transparent commercial relationships, not simply a collection of pages carrying referral links.

Questions to ask before signing a programme agreement

Request clear answers to the following:

• What exactly makes an acquisition payable?
• How is the commission base calculated?
• Which deductions and later reversals are permitted?
• How does attribution work?
• Is negative carryover applied, and at what level?
• What happens to existing customer commissions after termination?
• Which traffic sources require advance approval?
• How are changes to terms communicated?
• When are invoices or payments due?
• What process resolves reporting disputes?

Retain the applicable agreement and written commercial terms. A conversation with an account manager can clarify them, but it should not replace a documented understanding.

Frequently asked questions

Is an affiliate the same as a gambling operator?

No. An affiliate introduces customers or promotes services. The operator provides the gambling service. A company can have multiple business activities, but the roles should be distinguished.

Is revenue share based on customer deposits?

Not automatically. It normally applies to the revenue measure defined in the agreement, which is different from deposits.

Can affiliates earn commission without paid advertising?

Yes, an agreement can recognise qualifying referrals from permitted unpaid channels. That does not make publishing free: content, staff, tools and ongoing maintenance still have costs.

Does a larger audience guarantee higher income?

No. Geography, audience suitability, qualification, attribution and contract economics all matter. A smaller relevant audience can produce a different outcome from a large untargeted one.

What should a new publisher understand first?

Understand qualification and the commission base before estimating earnings. Once those are clear, assess compliance, tracking, costs and the resilience of the business model.
