Popunder advertising may not be the first thing that comes to mind, but it can be very useful for advertisers and affiliate marketers. Learn more about it and see how you can make it work for your campaign.
What Is Popunder Traffic?
It is traffic derived from a popunder ad. Instead of the more familiar pop ads that obstruct the user’s view, this version is slightly more discreet.
Here’s how popunder ads work in terms of display and function
With popunder ads, there will be a creative and/or a link on the publisher page, which will open another website. The difference with popunder is that it goes under the page that the user is currently viewing.
Difference between popunder and popup
Many mistakenly see this as pop vs popup, when the former is a more general term that refers to both pop-up and pop-under. However, popunder ads look exactly like pop-up ads. The only difference is where they appear.
Why Popunder Is Still Relevant in Affiliate Marketing
Even though the advertising world doesn’t hear about it that often, popunder for affiliates is still highly relevant. If you’re looking for high visibility at a low cost, this is normally a good match.
Key benefits for affiliates
Popunder ads are great for:
- Getting a lot of eyeballs on the offer at a low cost.
- Improving immunity to banner blindness without being intrusive.
- Minimal effort to scale.
Challenges and limitations
Should you use popunder traffic, you may get colder leads. The user may not be interested in making a purchase, so the click may just be driven by curiosity instead of intent. This means that you may have to do more work to achieve conversion.
There are other risks, such as increased bot traffic and limited brand safety. However, these can be addressed by using trusted ad networks like Kadam that support anti-fraud measures and placement filtering.

How to Launch a Popunder Campaign
After choosing a platform, follow the steps below to run the campaign.
Set up the offer and landing page
Since you’re an affiliate, the brunt of the work is connected with choosing a profitable offer. If the landing page is provided as well, your job is basically done. Otherwise, make sure that it loads quickly across all devices.
Identify campaign parameters
Here, you need to identify your target audience based on the various parameters supported by your selected platform. Then, limit how frequently the ad can be shown. If supported, also show the ads at the times that you think they will convert best.
Track and measure performance
If you’re using Kadam, you can track everything within the platform. Monitor key metrics such as CTR, CPL, conversion rates, and ROI. This way, you can make changes to the campaign if required.
How to Work with Popunder Traffic Efficiently
Popunder advertising can yield great results. So, keep this discussion in mind to help you do things right.
Common mistakes to avoid
Certain things can decrease the effectiveness of your campaign, such as:
- Using low-quality offers
- Not filtering unprofitable sites
- Not setting an ad frequency limit
Even if the offer isn’t mobile-specific, everything must be mobile-friendly.
Testing and optimization strategy
Since the general idea is to cast a wide net, start with broad targeting. Then, based on the initial data, limit your audience accordingly. Also, consider split testing to find out which creatives and audiences yield the highest ROI.
When to scale or stop a campaign
It’s good to scale when you’ve found the best audiences and the campaign is still highly profitable. However, consider pausing or stopping if the traffic quality drops or you’re not getting a positive ROI.
