Popunder ads are still one of the best traffic sources for affiliate marketers: they offer high visibility and cost efficiency with low restrictions. In 2025, this format will continue to thrive because of its ability to bypass ad blockers, ensure uninterrupted user engagement and conversions across multiple verticals like gambling, betting, finance, dating, antivirus.
Advertisers are increasingly turning to popunder ads traffic because of its affordability and scalability. With the right approach, popunder ads can generate big ROI while having relatively low cost per impression (CPM) compared to other ad formats. In this guide from ROIads experts, we will explore what popunder ads are, where to buy popunder traffic and the best strategies for 2025.
What Are Popunder Ads and How They Work
Popunder ads are a type of online advertising where an ad opens in a new browser window or tab behind the main content.
Unlike intrusive popup ads which demand attention and can be blocked by browsers, popunders remain hidden until the user closes their current window, so they are less disruptive while still offering high visibility. This format is effective because it allows the user to engage with the ad on their own terms rather than being forced to interact with it.
How Popunder Ads Work
When a user visits a site that has a popunder ads script, an ad window opens behind their active tab. When the user closes or minimizes their main browsing session, the ad is revealed, capturing their attention. This way the user is no longer distracted by their main browsing activity.
Key Advantages of Popunder Traffic:
- Non-intrusive engagement: Ads don’t interrupt the user experience right away, so better interaction rates.
- Fewer restrictions: Popunder ads in ad networks have fewer restrictions compared to other formats, so easier to launch and scale.
- No need for creatives: Unlike push or display ads, popunder campaigns don’t need complex creatives — just a quality landing page or pre-landing page for conversions.
- Bypass ad blockers: Many ad blockers don’t detect popunders, so higher visibility.
- Higher conversion rates: Users who interact with popunder ads are often more interested, so better conversion potential.
- Cost effective: Compared to native or display ads, popunder traffic is relatively cheap and offers big reach.

How to Buy Pop Traffic the Right Way
Buying popunder traffic is easy, but optimizing for conversions is a different story. A successful campaign is not just about clicks, it’s about getting engaged users who will take the desired action, whether it’s registration, deposit or purchase. Below are the key steps to get your popunder campaigns to deliver high ROI.
1. Choose the Right Ad Network
Not all popunder traffic is the same. Some networks offer premium traffic with higher engagement rates, others focus on volume-based low cost-impressions. Consider these when choosing an ad network:
- Traffic quality: Look for networks with bot filtering and high engagement rates.
- Supported verticals: Ensure the network performs well in your niche (iGaming, dating, finance, etc.).
- Targeting options: The more granular the targeting (geo, OS, device, time of day, etc.), the better control you have over your campaign.
- Bidding models: Check whether the network supports CPM, CPA, or hybrid bidding strategies.
- Reputation and reviews: Research past advertiser experiences to avoid low-quality or fraudulent traffic sources.
2. Define Targeting Parameters
A well-targeted campaign ensures your ads reach the right audience and don’t waste budget on irrelevant impressions. Adjust these:
- Geos: Where your offer converts best. Look at local laws, cultural factors, competition.
- Devices: Desktop and mobile traffic behave differently. Mobile traffic has more volume, desktop users convert more for some verticals.
- OS: Some offers do better on specific OS (e.g. Android vs iOS).
- Connectivity: Wi-Fi users have longer session duration, mobile data users convert differently.
- User behavior: Some networks allow retargeting, frequency capping and segmentation based on past user interactions.
3. Test Bidding Strategies
Bidding is key to balancing cost and profitability. Try these:
- Start with competitive CPM/CPA bids: If your bid is too low, you won’t get enough impressions to generate meaningful data.
- Micro Bidding: Adjust bids for different traffic sources, devices, or Geos to optimize cost.
- A/B test bid levels: Experiment with different CPMs or CPAs to find the best balance between cost and conversions.
- Automated rules: Some networks have AI-driven bidding adjustments to maximize performance.
4. Optimize Landing Pages
Landing page is the last step before conversion, so even the best traffic won’t work if your landing page isn’t good. Adjust:
- Speed: Popunder users will abandon slow pages quickly.
- Mobile friendliness: Since most popunder ads traffic comes from mobile, your page must be fully responsive.
- Clear CTA: Users must understand what to do (e.g. sign up, deposit, buy).
- Localization: Tailor content to the audience’s language and cultural expectations.
- A/B testing: Test different designs, messaging and CTA placements.
5. Monitor Traffic Quality
Not all traffic sources are equal and some will bring bots or low quality traffic. Here’s how to maintain traffic quality:
- Analytics tools: Track conversion rates, bounce rates and session duration to identify weak traffic sources.
- Postback tracking: Proper conversion tracking allows you to see which sources are generating real results.
- Blacklist non-performing sources: If some publishers don’t convert, remove them from your campaigns.
- Monitor fraud indicators: Sudden spikes in impressions without conversions, unusual IP patterns and high bounce rates may indicate bot traffic.
By following these steps you can optimize your popunder campaigns, avoid wasting ad spend and increase conversions. Popunder advertising is all about data driven optimization and continuous tweaking.
Cheap Popunder Ads Traffic vs. Premium: What to Choose?
Not all popunder traffic is equal. While buying cheap popunder traffic may look attractive, it often lacks the quality for profitable campaigns. Premium traffic is more expensive but converts better.
Key Differences Between Cheap and Premium Popunder Traffic
| Feature | Cheap Popunder Traffic | Premium Popunder Traffic |
| Price | Low | Higher, but justified |
| Traffic Quality | Mixed, sometimes bot traffic | High-quality, real users |
| Conversion Rate | Low to medium | High |
| Best Use Case | Volume-based campaigns | Targeted, high-ROI campaigns |
For long-term profitability, invest in premium traffic, especially for verticals like gambling, finance and dating. For example, ROIads offers premium traffic only, so you get better quality and better conversion rates for your ads.
How to Optimize Popunder Ads for Maximum ROI
Once your campaign is live, optimization is key. Follow these strategies:
- A/B Test Landing Pages:
Test different layouts, CTAs, content. Test variations in headlines, button placement, colors and offers to see what drives the most engagement and conversions. Use heatmaps and session recordings to see how users behave and optimize page elements accordingly. - Use Micro Bidding:
Bid at a granular level to maximize efficiency with Micro bidding feature. Increase bids for top-performing traffic sources and decrease bids for underperforming ones. Segment bidding by geo, device and ad placement to optimize cost. - Monitor Traffic Sources:
Blacklist underperforming sources. Regularly analyze which traffic sources bring quality conversions and blacklist the ones that bring high bounce rate or low engagement. Work with ad networks that provide traffic sources transparency to make data-driven decisions. - Leverage Frequency Capping:
Control how many times a user sees your ad to avoid fatigue. We recommend setting a frequency cap of 1-2 impressions per day to avoid banner blindness and get better user engagement and higher conversion rates. Test different frequency caps across campaigns to find the optimal balance between exposure and user interest. - Analyze Conversion Data:
Use postback tracking to measure performance and adjust campaigns accordingly. Set up proper tracking to attribute conversions accurately and optimize based on real-time data. Identify key drop off points in the funnel and adjust landing pages, targeting and ad creatives to improve conversions.
Future of Popunder Ads Traffic: What to Expect in 2025

- AI-Driven Optimization: More networks will introduce machine learning-based bid adjustments.
