The gambling industry is one of the most profitable verticals in affiliate marketing, and popunder ads (also known as “pops”) are still one of the best traffic sources for promoting gambling offers. With the right approach popunder traffic can give you high conversion rates while keeping costs lower than other ad formats like push notifications or native ads.
In this guide from ROIads experts, we’ll cover how to promote gambling on popunders in 2025, including campaign setup, best practices, ad creatives, landing pages and optimization strategies. Whether you’re an experienced affiliate or just starting with gambling pop ads, this guide will help you maximize ROI on popunder campaigns.
What Are Pop Ads and Why Gambling Promotion on Popunders is Effective?
Popunder ads are a type of ad that opens in a new browser tab behind the main window when a user clicks on a website. Unlike intrusive pop-up ads that appear on top of the content, popunders remain hidden until the user closes or minimizes their main browser window.
Why is Promoting Gambling on Popunders a Good Idea?
Popunder advertising is one of the best channels for promoting gambling offers due to its high visibility, affordability and no restrictions compared to other traffic sources. Here’s why pop ads are a great choice for gambling promotion.
- No Strict Restrictions on Gambling Advertising
Unlike Facebook, Google Ads and mainstream influencer marketing, popunder ads do not have strict gambling-related restrictions. Many ad networks allow direct gambling promotion, so affiliates can run campaigns without worrying about compliance issues or account bans. This makes popunder traffic one of the few scalable and sustainable options for gambling promotion.
- High Visibility and Engagement
Pop ads appear in a separate tab behind the user’s main window. So they remain open and visible even after the user moves on from the initial page. Once the user closes or minimizes their active browsing session, they will notice the popunder ad, so higher engagement rates compared to other intrusive formats. Since the ad does not immediately interfere with the user’s browsing experience, it reduces ad fatigue and banner blindness.
- Affordable Traffic with Low CPM Rates
Compared to native ads and paid social traffic, popunder ads have lower CPM rates. This means affiliates can test multiple campaigns and optimize traffic sources without burning big budgets. And with low cost per impression you can scale successful campaigns more efficiently and get better ROI on gambling offers.
- Broad Audience Reach Across Mobile and Desktop
Popunder advertising supports mobile and desktop traffic, so affiliates can reach a wider audience across different devices. Since gambling users are active on multiple platforms, running targeted campaigns for mobile and desktop users separately can give you higher conversion rates. Pop traffic sources cover premium and remnant inventory, so you get a mix of high-quality and scalable traffic at different price levels.
- Ideal for Soft Conversions and Lead Generation
Gamblers need multiple touchpoints before signing up and depositing. Popunders are great for soft conversion offers, like free spins, welcome bonuses and no-deposit incentives. Since the traffic is cheaper, advertisers can drive large volumes of traffic to their landing pages and nurture leads and retarget them through other marketing channels.
By using pop ads for gambling campaigns, affiliates can benefit from a cost-effective, unrestricted and scalable traffic source that performs well across multiple geos.
Why is Promoting Gambling with Popunder Ads a Valuable Strategy?
In this section, we’ll cover the gambling market, its size and growth potential. But first, let’s break down the different types of games in the gambling vertical.
Types of Gambling Offers
Let’s take a quick look at the iGaming industry and outline the main types of games it includes. iGaming offers can be divided into five main types:
Casino
In casinos, players test their luck and show off their skills in a variety of games where there’s a chance to win big. Key mechanics include slot machines, roulette, blackjack and other popular games. Casino offers are for players looking for variety, interactivity and to hit the big jackpot.
Sports Betting
Betting is another major branch of the gambling industry. It’s betting on sports and eSports events. Types of bets can vary: straight bets on a winner, bets on the number of goals or points scored, exact scores and many other variations. Betting offers are for sports enthusiasts and those who enjoy using their analytical skills to make money.
Poker and Card Games
Card games include not only the super popular poker, but also Texas Hold’em, Omaha, blackjack and many other variations. The main difference with these games is that players often play against real people, not just algorithms. This means users can rely not only on luck but also on their skills. This vertical has many betting options for any budget.
Bingo
Bingo is a fast and fun game where players try to be the first to mark off the correct numbers on their cards and win prizes. This category is for players looking for quick entertainment and easy wins as bingo sessions are short and the chances of winning small prizes are high.
Lotteries
Lottery offers are about massive wins with minimal investment. Players rely on luck in this category. There are many types of lotteries, scratch cards, raffles and instant win games. This category often uses big winner stories and targets the widest audience possible.

The Best Ways to Promote Gambling on Popunders: 5 Steps
Now that we’ve seen why pop ads are effective for gambling promo, let’s go through the steps to launch a successful gambling promotion on popunders. Follow this guide to maximize conversions and scale campaigns.
1. Choose the Right Gambling Offer in an Affiliate Network
Selecting the right offer is the foundation of a profitable popunder campaign. Gambling offers come in different formats, and their success depends on several factors:
1. Geo Targeting – Some gambling offers are geo-restricted, meaning they only accept traffic from specific countries. Tier 1 geos (USA, Canada, Germany) offer higher payouts, but are also more competitive and expensive. Tier 2 and Tier 3 geos (Brazil, Indonesia, India) have cheaper traffic and can be a better choice for affiliates testing pop traffic.
2. Payout Model – Gambling offers usually work on:
- CPA (Cost Per Acquisition) – Payment per first deposit.
- RevShare (Revenue Share) – You earn a percentage of player losses.
- Hybrid (CPA + RevShare) – A mix of upfront payout and long-term earnings.
Bonuses and Promotions – Offers with no-deposit bonuses, free spins or cashback deals convert better. These should be reflected in your landing pages and ad creatives.
2. Understand Your Gambling Audience
Gambling campaigns require exact targeting. Popunder traffic is broad but different segments respond to different pre-landing landing pages.
Two Main Gambling Audience Types:
1. Players Looking to Win Money – This audience wants high bonuses, winning strategies and fast withdrawals. Your ads should highlight:
- Success stories of big wins.
- High RTP (Return to Player) rates.
- Exclusive deposit bonuses and cashback offers.
2. Players Seeking Entertainment – These users gamble for fun, adrenaline and excitement. Your ads should focus on:
- The thrill of betting or spinning reels.
- The game atmosphere, visuals, and animations.
- Engaging slogans like “Experience the thrill!”
💡 Pro Tip: Use demographic insights for each geo — age, interests, and payment methods. For example, players in Brazil use PIX payments, Indonesian users use local e-wallets.
3. Design High-Converting Landing Pages for Pop Traffic
Unlike, for example, of native ads, which require killer ad creatives to grab user attention, popunder traffic works differently — it doesn’t rely on banners or ad copy. Instead, the key to success is having a high-converting landing page that engages the user instantly. In some cases, using a pre-landing page can warm up traffic before sending them to the final offer page.
Many CPA networks provide pre-made landing pages for their gambling offers, so you don’t need to create one from scratch. But if the offer doesn’t come with its own landing page, follow these guidelines:
Best Practices for Landing Pages to Run Gambling Campaigns on Popunders:
- Fast Load Speed – Popunder traffic is high-volume. Slow pages = lost conversions. Use lightweight designs.
- Auto-Play Elements – Animated banners, spinning wheels or flashing bonus offer works well.
- Localized Content – Show text in local language and use country-specific currency.
- Simple Registration Flow – Reduce steps to sign up. Single-click registration or social login improves conversions.
High-Performing Gambling LP Types:
- No-Deposit Bonus Pages – “Claim $10 Free Bonus Now!”
- Spin-to-Win LPs – Interactive scratch cards or spinning wheels.
- VIP Club LPs – Exclusive high-roller programs for serious players.
4. Set Up Your Gambling Popunder Campaign
Launching a pop campaign requires proper targeting and bid strategy. In ROIads, you can start a promoting gambling on popunders with these targets:
- Geo, Device, OS, Browser, Connection Type.
- Micro Bidding to adjust source-level bids.
Recommended Campaign Settings for Gambling Popunders:
- Broad Targeting to Start – Run a wide campaign first to collect data, then optimize.
- Bid Adjustment by Device – Mobile popunder traffic converts well, but desktop users have higher deposit rates.
- Ad Frequency Capping – Set to 1-2 impressions per 24 hours per user to avoid ad fatigue.
💡 Optimization Tip: Gambling offers perform best on Chrome and Android. Exclude Safari and older OS versions if they show poor conversion rates.
5. Monitor Performance and Optimize Your Gambling Campaigns
Tracking conversions is crucial for scaling gambling pop ads. Use postback tracking with tools like Voluum, Keitaro, RedTrack or BeMob to track:
Key Metrics to Track:
- CR (Conversion Rate) – Are users signing up?
- FTD (First-Time Depositors) – The main KPI for gambling campaigns.
- ROI (Return on Investment) – Ensures long-term profitability.
💡 Optimization Tips:
- Increase bids on high-ROI traffic sources and exclude low-performing publishers.
- Adjust targeting for specific browsers and devices that perform best.
- Use AI Bidding to automate traffic source optimization.
Conclusion
Gambling is one of the most profitable verticals in affiliate marketing and pop ads offer the best of both worlds — affordability and scale. By using high-converting offers, LPs and smart bid strategy, you can drive FTDs and long-term profits.
