Affiliate marketing is one of the most talked-about acquisition channels in iGaming, yet one of the least critically examined. The pitch is seductive: a performance-based model where you only pay when a player deposits. No wasted impressions, no brand spend disappearing into the ether, no guesswork. Just results.
Except the question most online casino operators forget to ask is: results measured how, and profitable for whom?
If you’re building or scaling an affiliate programme, this is the conversation worth having before you sign another CPA deal.
What are Affiliates in iGaming?
Affiliates are publishers, websites, content creators, comparison portals, tipster communities and YouTube channels. Affiliates can be found in many mediums, with the sole purpose to drive traffic to online casino brands via tracked links in exchange for a commercial arrangement.
The deal structures:
The three main deal structures are CPA (a fixed fee per acquired player), RevShare (a cut of that player’s net gaming revenue over time), or a hybrid of both.
The affiliate ecosystem is mature, competitive, and enormous. The best affiliates rank for the exact keywords your players are searching such as “best online casino UK,” “top slots bonuses,” “safe betting sites” and they’ve spent years building domain authority you can’t replicate overnight. That’s genuinely valuable. The problem is that the value of an affiliate relationship is almost never as simple as the volume of first-time deposits they send you.
The FTD Illusion:
First-time deposits are the currency of affiliate marketing in iGaming. They’re what CPA deals are built around, what monthly reports are structured around, and what most affiliate managers are measured on. They are also, bluntly, a misleading metric for profitability.
An FTD tells you one thing: a player deposited once. It tells you nothing about whether they’ll ever deposit again, what stakes they play at, whether they claimed a Welcome bonus and immediately churned, or whether their 90-day LTV comes anywhere close to covering the cost of acquiring them.
Here’s where the critical thinking matters. In competitive markets, industry behaviour suggests a significant portion of affiliate-referred players, particularly those arriving via bonus comparison sites, make a single deposit, claim the welcome offer then leave. They’re not players in any meaningful sense.
They’re bonus arbitrageurs, and if your CPA deal doesn’t include wager-through protections, minimum deposit thresholds, or clawback provisions for early churn, you are paying full commission for players who will never generate profitable GGR.
The FTD as a success metric flatters the affiliate and obscures the operator’s actual position. Before you celebrate a record month of affiliate-driven deposits, ask what percentage of those players made a second deposit. That number will tell you far more about the health of your affiliate programme than FTD volume ever will.
The Opportunity Cost Nobody Quantifies:
This is the part of the affiliate conversation that gets skipped most often, because it requires operators to look critically at their own budget allocation rather than just at the affiliate’s performance.
Opportunity cost, in this context, is simple: every pound you spend on affiliate CPA fees is a pound that isn’t being spent on something else. The question is whether affiliates represent the best use of that pound relative to your other acquisition options.
Consider the maths. If you’re paying £150 CPA across your active affiliate portfolio and your average 90-day player LTV is £120, you are structurally loss-making on first-time deposits before you’ve factored in welcome bonus costs, payment processing fees, KYC overhead, or customer support.
You’re betting (and it is a bet) that retention will eventually close the gap. Sometimes it does. Often it doesn’t, and by the time you’ve run the cohort analysis, the budget has already been spent.
Now compare that against the marginal return from equally-funded investment in owned channels (CRM, Social, Content, SEO). The opportunity costs is understanding, what ROI could you get from £150 in your owned channels?
Affiliates present their channel as cost-efficient because the cost is visible only at the point of conversion. The opportunity cost to you is spending this budget on alternative channels for example, SEO content or link buying to increase you brand search rankings which has moments of being intangibility. That invisibility is doing a lot of heavy lifting and often overlooked.
This doesn’t mean affiliates are the wrong channel. It means they need to earn their place in your acquisition mix the same way any other channel does.
Finding Partners That Actually Add Value
If you’ve accepted that FTD volume is not the right north star, you need a different framework for evaluating affiliate relationships and for deciding which ones to build, which to renegotiate, and which to walk away from.
Segment by player quality, not player volume. Pull your affiliate-referred players into cohorts by source and run 30, 60, and 90-day LTV by partner.
You will almost certainly find that a small number of affiliates are responsible for the majority of your profitable player base and that several partners are sending you acquisition spend you’ll never recover. Treat those numbers as a renegotiation mandate, not a dashboard metric.
Diversity in acquisition source is vital but you need to do this in a ‘safe’ manner, balancing volume and player value. Interrogate traffic sources before you sign. Ask prospective affiliates for their traffic breakdown.
Organic search from content that builds genuine user intent through game reviews, strategy guides and sport-specific betting content that produces meaningfully better players than bonus comparison pages optimised purely to arbitrage Welcome offers. Organic traffic source will likely produce higher value and long term retention at lower conversion rate % vs efforts to acquire.
The affiliate who drives 50 players with strong second-deposit rates is worth more than the one driving 200 single-deposit bonus hunters.
Structure deals that align incentives properly. A pure CPA deal incentivises the affiliate to optimise for the deposit event. A RevShare or hybrid deal incentivises them to care about what happens after. For your most important affiliate relationships, this alignment matters enormously. If your partner profits whether or not your player ever deposits again, you don’t have a partnership, you have a transaction.
Protect your compliance position. One affiliate promoting your online casino to the wrong audience, in the wrong market, with non-compliant messaging, can generate regulatory exposure that dwarfs their entire FTD contribution. Vet compliance posture as rigorously as you vet traffic quality.
The Bottom Line:
Affiliates can be a legitimate and valuable part of an iGaming acquisition strategy. But they are not cost-free, they are not low-risk, and the first-time deposit is not the right measure of whether they’re working.
The operators who win at affiliate marketing are the ones who treat it like any other significant marketing investment: running the real numbers, asking hard questions about opportunity cost, and building relationships with partners who send players worth keeping, not just players worth counting.
Run your cohorts. Interrogate your CPAs. And the next time an affiliate sends you a record FTD month, ask what it cost you to get there.
