In the world of online Gambling advertising, getting traffic and conversions is key. One of the best ways to promote iGaming offers is popunder ad format — a gentle but effective type ad advertising that opens behind the main browser window. Unlike pop-ups, popunders let users focus on what they’re doing and come back to the ad when they’re done.
This article will go into the nitty gritty of promoting popunder traffic in Gambling, the types of offers, and how to run a successful campaign.
Popunder is a part of pop ads. This is a type of online advertising that opens in a new window behind the main one when users navigate the browser. So they stay open even if the user closes the page they were on.
Unlike pop-ups which can be super annoying and irritating to users, popunders are more subtle. And because they don’t interrupt the user’s experience, pop ads can grab attention without frustration. Users will notice these ads when they’re done with what they’re doing on the page, so they’re more receptive to the content.
This ad format is flexible and can be used for various Gambling purposes like promoting online casinos, special offers, or new games.
When it comes to Gambling, Facebook and Google Ads have strict rules. Popunder ads in Gambling instead have less restrictions, so affiliates can run their campaigns without the hassle of compliance issues or account suspensions.
Popunder ads open in a new tab behind the main one, so they stay visible even when users close the original page. When users close their browser they will notice the popunder, resulting in higher engagement rates compared to other ad formats. Since these ads don’t interrupt the user right away, they minimize ad fatigue and the chance of users ignoring them.
Compared to native ads and paid social media traffic, popunder ads have lower cost per thousand impressions (CPM). This means affiliates can test different campaigns and optimize their traffic sources without overspending.
Popunder ads in Gambling work on both mobile and desktop, so affiliates can reach a bigger audience. Since gamblers engage on multiple platforms, running separate campaigns for mobile and desktop can result in higher conversion rates.
