Why This Page Exists
Most casino review sites disclose their affiliate relationships in a single sentence buried in the footer. We think you deserve more than that. If you are using Sister Guide to decide where to deposit your money, you should understand exactly how this site makes its money — not as a legal technicality, but as a proper explanation.
This page lays out our business model in full: how we earn revenue, how that revenue does and does not influence our content, what happens when you click a link on our site, and where we draw the lines that protect our editorial independence.
We could have written three lines and been legally compliant. We chose to write this page instead because hiding the details is exactly the kind of behaviour we criticise in the casinos we review.
How Sister Guide Makes Money
Sister Guide is funded through affiliate commissions. When you read a review on our site and click a link that takes you to a casino, that link contains a tracking code. If you go on to create an account at that casino — and in some cases make a deposit — the operator records that Sister Guide referred you and pays us a commission.
This is the primary way we generate revenue. We do not charge readers for access. We do not run banner advertisements from third-party ad networks. We do not sell your data. The affiliate model is what keeps Sister Guide free to use.
Commission structures vary between operators but generally fall into two models. The first is a cost-per-acquisition payment, where we receive a fixed fee when a referred player registers and deposits. The second is a revenue share model, where we receive a percentage of the net revenue the casino earns from referred players over time. Some operators offer a hybrid of both.
Not every casino listed on Sister Guide has an affiliate programme, and not every programme offers the same terms. Some operators pay significantly more than others. Some pay nothing at all — we review certain casinos purely because they are relevant to the UK market and our readers should know about them, regardless of whether there is a commercial arrangement behind the listing.
What Happens When You Click a Link
When you click a link on Sister Guide that takes you to a casino, here is what happens step by step:
| Step | What Happens | Who Is Involved |
|---|---|---|
| 1 | You click a casino link on Sister Guide | You and Sister Guide |
| 2 | The link redirects through an affiliate tracking platform, which may place a cookie on your device | Affiliate platform (operated by or on behalf of the casino) |
| 3 | You arrive at the casino's website | You and the casino operator |
| 4 | If you register or deposit, the tracking cookie confirms Sister Guide referred you | The casino's affiliate platform |
| 5 | The operator pays Sister Guide a commission based on the agreed terms | Sister Guide and the casino operator |
Once you click through to the casino, everything from that point — your personal data, your deposits, your gameplay, your withdrawals — is handled by the casino operator under their own terms, privacy policy, and UKGC licence obligations. Sister Guide never sees your casino account details, financial information, or gambling activity.
The tracking cookie identifies the referral source, not you personally. We cannot connect a commission payment back to a specific individual. The data that flows back to us is limited to a transaction reference and a commission amount.
If you have rejected affiliate cookies through our cookie banner or your browser settings, the tracking will not work. You will still reach the casino — the link functions normally — but the referral will not be attributed to Sister Guide, which means we will not earn commission on that visit.
The Conflict of Interest — And How We Manage It
Any website that earns money by referring you to a casino has a financial incentive to send you to whichever casino pays the most. That incentive exists for Sister Guide just as it exists for every other affiliate site in the industry. Pretending otherwise would be dishonest.
The difference is in what you do about it. At Sister Guide, our editorial process and our commercial relationships are structurally separated. The team members who test casinos and write reviews do not know the commission rates attached to individual operators. Casino scores are determined entirely by our five-category evaluation methodology — Safety and Licensing, Bonus Fairness, Game Selection, Withdrawal Speed, and Customer Support — which is published on our How We Rate page. An operator's commercial value to Sister Guide has no bearing on its review score.
This separation has real consequences. We have given low scores to operators that pay high commissions. We have given strong scores to operators where our commercial terms are modest or where we have no affiliate relationship at all. We have declined partnerships with operators that failed our licensing requirements, walking away from revenue because the casino did not meet the standards we set for inclusion on the site.
We are not claiming our system is flawless. Unconscious bias is difficult to eliminate completely. But we have built structural safeguards to minimise its influence, and we publish our methodology so that anyone can evaluate the relationship between our scores and the evidence behind them.
What Affiliate Revenue Does Not Buy
A higher review score
Scores are calculated using our five-category methodology. Commission rates are not a variable in the formula. The methodology is published and the weights are fixed.
A better ranking position
The order in which casinos appear on our comparison pages is determined by score, not by commercial value. If a lower-paying casino scores higher, it ranks first.
Editorial favours
We do not remove negative findings because an operator asked. We do not soften language to protect a commercial relationship. If a withdrawal took four days when we tested it, the review says so.
Inclusion on the site
Every casino listed on Sister Guide must hold a valid UKGC licence. We have turned away operators willing to pay generous commissions because they could not demonstrate valid licensing.
Immunity from re-assessment
If a listed casino's performance deteriorates — slower payouts, worse support, predatory bonus changes — we update the review and adjust the score. Active partnerships do not grant protection from honest assessment.
Silence about problems
We disclose UKGC penalties, regulatory actions, and corporate issues on our casino network pages. A commercial relationship does not buy our silence about an operator's history.
Why We Believe This Model Works
The affiliate model catches criticism, and some of it is deserved. There are genuinely poor affiliate sites that rank casinos by commission rate and present it as a recommendation. The model has been misused enough that scepticism is healthy.
But the model itself is not the problem — the execution is. Affiliate revenue is what allows Sister Guide to exist as a free resource. Without it, we would need to charge readers for access or accept direct payments from operators for content, both of which would be worse for independence.
The affiliate model, executed properly, creates a reasonable alignment of interests. Operators want quality referrals from players who have a good experience. Readers want honest information that helps them find casinos worth their time. Sister Guide wants to produce content good enough that readers trust us, click through, and the referrals convert. If our reviews are inaccurate — if we recommend bad casinos — readers stop trusting us, traffic drops, and revenue disappears.
Our financial incentive and your interest as a reader are not perfectly aligned, but they are not opposed either. The gap between them is where editorial standards and structural safeguards live, and we have invested in both.
Affiliate Revenue and Responsible Gambling
Earning money from casino referrals comes with a responsibility we take seriously. We are directing people to gambling sites, and gambling carries real financial and emotional risks. That reality must never be obscured by commercial interests.
Every casino we list is assessed on the strength of its responsible gambling tools — deposit limits, session timers, cooling-off periods, and self-exclusion options. Operators that make these tools difficult to find or activate are penalised in our scoring.
We include links to support services across our site because they matter. GamCare provides free, confidential advice for anyone affected by problem gambling. GamStop offers a national self-exclusion scheme covering all UKGC-licensed sites. Our Responsible Gambling page provides a detailed guide to every tool available to UK players. These resources exist for moments when gambling stops being entertainment, and no affiliate commission is worth pretending those moments do not happen.
We will never frame gambling as risk-free. We will never suggest that bonuses guarantee profit. And we will never prioritise a commercial relationship over the wellbeing of someone reading our site.
