Popunder Advertising: Quick Start (Setup, Anti-Fraud, and Metrics)

Learn how to attract potential customers through popunder advertising for as little as $0.0002. Let’s break down the format’s unique features, setup, and key metrics.

What Is Popunder Advertising in 2025?

It could be the right low-cost strategy for you, delivering a massive number of quality leads. Pop traffic can generate up to 120 million clicks per day and deliver consistent revenue. Advertisers can easily find publishers willing to feature this ad format at a low cost. 

Main Features of the Popunder Format

Popunder is an ad format that automatically opens in a new browser tab behind the page a user is viewing. A popunder (aka click-under or one-click) ad is displayed in the background, but the key is that the user cannot simply scroll past it. It remains visible until the user actively closes it.

It’s a non-intrusive format that respects the user’s browsing session and UX. Meanwhile, advertisers benefit from maximum visibility and excellent CPL and CPI metrics.

Why Advertisers Choose Popunder Campaigns

Popunders thrive on volume and engagement. Set them up properly, match them with the right offers, and you’ll get a steady stream of leads and an impressive ROI.

It’s a flexible format that performs across the full spectrum of verticals, from compliant offers to adult and high-risk categories and more aggressive “grey-hat” niches, including:

• iGaming (betting, casinos)
• Nutra offers (health, weight loss)

This form of advertising is effective for international traffic (targeting Western countries with high click-through rates).

Here, we’ve gathered the main advantages of the popunder format:

• Affordability. You can start running popunder ads for as little as $0.0002 per view.
• Low CPC bids starting from $0.001. You can conduct split testing without incurring high financial costs.
• No restrictions. Popunders work across all platforms and with diverse mainstream verticals, including finance, adult content (18+), movies, games, and software.
• Scalability. You can achieve millions of clicks per day.
• Auto-optimization. Popunders are compatible with other webmaster tools and can be optimized for maximum efficiency.
• Simple adoption. Campaign setup is relatively simple, and you do not need to design complex push creatives.

First Steps: How to Launch Popunder Ads

We’ve created a short guide for those planning to use pop traffic for the first time. It involves just three stages: deciding what to promote and where, defining your target audience, and setting your budget.

Offer Selection and Ad Configuration

To get the most out of this massive web traffic source, register with Kadam. We offer low-cost ad placement, a 100% fill rate, and up to 120 million clicks per day. Our iGaming clients have achieved an ROI of over 320%, proving the service’s effectiveness.

Note that your chosen ad network should provide tools for campaign setup, retargeting, integration with trackers, and a reporting system. 

Deciding on Profitable GEOs: Popunder

After registering, simply upload your artwork and the link to your landing page and configure your display settings. Here, you’ll need to define the region and audience that best match your offer. 

Then, you’ll need to decide on the right popunder targeting. African countries are ideal for some niches, while developed markets work better for others. For example, statistics show that LatAm and India are high-performing GEOs for betting ads.

Budget Planning and Payment Models

Popunders primarily use the CPC (Cost per Click) model, so you pay for each click. All cost information will be available in your account dashboard (under the “Clickunder” section). The price depends on the site categories and regional settings, but it starts at just $0.0002.

To gather reliable statistics, we recommend setting aside $20–$50 for Tier 2 countries and $100–$200 for Tier 1 countries. It’s worth testing several campaigns with unique designs.

Popunder Settings and Optimization

Popunder optimization is easy, and you will need it to increase the relevance of your offers. The main components include:

• Adjusting frequency based on overall statistics.
• Optimizing the landing page design and user flow.
• Adjusting CPC bids based on campaign performance.

Ad Frequency: Popunder Timing

A good frequency is 1–2 impressions per user per day. Seeing pop ads too often can become annoying. Also, don’t forget about popunder timing: in some markets, conversion growth can be seen in the evenings or on weekends.

Testing Visuals

Find the “campaign management desk” and your campaign name. Then, change the visuals using your landing builder to run A/B or split tests. This might help you determine what works best: bright or minimalist designs, video elements, or static images.

Conversion Tracking

In your Kadam dashboard, you will see which web or mobile traffic categories are performing best and can quickly turn off underperforming sources. To optimize your budget and boost revenue, use trackers and monitor CR and CTR.

Fighting Popunder Fraud and Ensuring Traffic Quality

To get the most out of push and pop ads, advertisers must ensure that they reach real users. Sometimes, fraudsters and bots get in the way.

Types of Fraud

The most frequent issues include:

• Bots, botnets, and clickers that mimic real user behavior.
• Farmed traffic – clicks generated from a single source (farm) to inflate numbers.
• Viruses that aggressively open tabs behind the user’s active tab.

Anti-Fraud Tools Popunder Advertisers Use

Kadam uses a multifactor mechanism to ensure traffic quality. The platform can detect and block low-quality and fraudulent sources. To achieve this, we’ve implemented services that protect against bots and click fraud, along with IP blocking.

Ad Filtering and Moderation

Before launch, every campaign undergoes an automated review. We do this to ensure it complies with the networks’ policies. We do not display ads on low-quality sites and help you set up popunder targeting by mobile operators, platforms, and browsers, as well as configure blacklists, whitelists, smartlinks, auto-rules, and proxies.

Popunder Metrics and Analytics for Advertisers

To see if your pop ads are working, you need to analyze their performance and be aware of the stats.

CTR, CR, and eCPM in Popunder Campaigns

Here are the basic terms you must learn:

CTR popunder (Click-Through Rate) shows the percentage of users who clicked on your ad.

CR (Conversion Rate) reflects how many people completed a target action, e.g., registering.

eCPM popunder (Effective Cost Per Mille) is a metric that shows your revenue per 1,000 impressions. It helps compare the effectiveness of different traffic sources.

How to Interpret Campaign Statistics

Since popunders (landing pages) open automatically in a new tab, their view rate is effectively 100%. Hence, the traditional CTR metric is not that relevant.

A good CR popunder rate depends on the niche, but it typically ranges from 3% to 8%. For crypto, the rates should be higher, while for e-commerce, they may be lower.

The higher the eCPM, the more profit you get. For example, a campaign with 100,000 views and $200 in profit has an eCPM of $2. If the metric drops, it’s time to revise your designs.

Common Mistakes in Analyzing Metrics

Avoid drawing conclusions from small sample sizes, as the data may not be representative. It’s better to wait than to rush into a redesign.

A popunder campaign is part of a larger ecosystem. Segment your metrics by region and device type to learn which segments yield the best results.

We also recommend looking at numbers week by week instead of chasing instant results. Check which channels bring real leads and how well you can keep them coming back.

Should You Run Popunder Campaigns in 2025?

Yes, and the pop case studies prove it. It’s the most affordable and effective way to get a steady stream of visits, cheap clicks, and massive reach without harming the user experience. Plus, website monetization increasingly relies on popunders, so many publishers are willing to host them.
