What Are Sub-Affiliate Networks?

Affiliate marketing plays a vital role in the growth of the iGaming industry, providing operators with a cost-effective and performance-driven way to acquire new players. While most affiliates are familiar with the standard model of promoting brands in exchange for commission, fewer fully understand the potential of sub-affiliate networks. These systems allow experienced affiliates to build a second tier of income by referring other affiliates into the program, creating an additional revenue stream and fostering a broader, scalable network.

The basics of Sub Affiliates

A sub affiliate is simply another affiliate who has been referred into an affiliate program by someone already within it. Instead of only earning commission based on the players you directly refer to a casino or sportsbook, you also earn a smaller share of revenue from other affiliates that you bring into the program.

This is often called a two-tier or multi-tier affiliate structure. You earn a commission based on the net revenue those sub affiliates generate for the operator. You are not earning from the customers themselves but from the performance of the affiliates you recruited.

For example, if you refer an affiliate who then earns $1,000 in commission through a specific casino program, and your sub-affiliate share is five percent, you would receive $50 of that amount each time they hit that figure. While that may seem small at first glance, the power of sub-affiliate models lies in volume and consistency. With multiple affiliates under you, those figures can build quickly into a passive and scalable revenue stream.

How Sub-Affiliate Networks Work

The process of working with sub affiliates is straightforward:

This model suits affiliates who have a wide network of contacts or strong authority within the iGaming space. It also appeals to content creators and marketers who may not want to compete in high-cost, high-volume acquisition channels but are well-positioned to bring others into the affiliate ecosystem.

Why iGaming Is Well Suited to Sub Affiliate Models

The iGaming industry is crowded and competitive. Larger affiliates tend to dominate top search results, have significant budgets for PPC campaigns, and are often years ahead in terms of backlinks and reputation. For smaller affiliates or those just starting out, it can be difficult to carve out a profitable niche using traditional acquisition methods.

Sub-affiliate networks offer an alternative approach. Instead of competing head-on, affiliates can act more like network builders, earning through others who are actively promoting casinos and sportsbooks. This model works particularly well in iGaming because the lifetime value of players is high and most affiliate programs offer recurring commissions. As long as your sub affiliates are active, you continue to earn without needing to bring in new players yourself.

In essence, this is a model that rewards mentorship, strategy, and relationship-building, rather than simply chasing traffic at scale.

Where to Find Sub-Affiliate Opportunities

Many of the major affiliate platforms support sub-affiliate structures, although it’s not always clearly advertised. If you are already part of an affiliate program, the first step is to check whether the platform offers a sub-affiliate or referral component. You can also reach out directly to your affiliate manager for confirmation.

In some cases, you will find platforms that offer white-label solutions which include affiliate management tools as part of their service. These can be particularly useful if you're looking to build a branded affiliate network of your own.

Benefits of Sub-Affiliate Networks

Passive Revenue Potential

Once you refer an affiliate who knows what they’re doing, you continue to earn from their success without any ongoing effort. This creates a layer of passive income that can support or supplement your core affiliate activity.

Increased Stability

Sub-affiliate revenue can help balance fluctuations in your own performance. If your site traffic dips or you experience seasonal drops in conversions, your sub-affiliate income can provide more consistent earnings.

Scalable Without Significant Overhead

Instead of hiring staff or investing heavily in ad spend, you can grow your income by building out your network of sub affiliates. With the right relationships, this creates a self-sustaining system that requires relatively little maintenance.

Brand and Community Building

Those who actively support their sub affiliates with training, onboarding resources, or strategic guidance often build stronger relationships that result in better long-term performance. It also enhances your reputation in the affiliate community.

Challenges to Consider

Quality Control

You won’t always have visibility into how your sub affiliates operate. If they use misleading advertising, break compliance rules, or otherwise behave in a way that violates program terms, you may be held partially accountable by association.

Modest Earnings per Affiliate

The percentage you receive from sub affiliates is usually quite low, often between two and ten percent of their net earnings. While this can scale, it means you need either a large network or high-performing individuals to generate meaningful income.

Ongoing Engagement

Although it’s considered passive income, a successful sub-affiliate strategy does require some level of engagement. Checking in, offering support, and helping new affiliates get started can make a significant difference, especially early on.
