Popunder advertising can be a format where an ad opens in a very new browser window or tab behind the person’s active window. It’s built to be less intrusive than pop-ups, appearing only as soon as the user has left or minimized the primary site window, creating a more seamless browsing experience. Popunders might be highly effective for advertisers looking to reach engaged users while minimizing the disruption caused by more overt ad formats.

What is Popunder Advertising?
Unlike traditional pop-up ads, which open directly while watching user’s screen, popunder ads appear “behind” the key browser window. Because they remain hidden before user closes or minimizes the principal window, they’re less interruptive and have lower odds of causing frustration. This format is popular in web marketing because it can reach users effectively without compromising the browsing experience.



Why Use Popunder Advertising?
Popunder advertising offers several unique benefits:

Higher Engagement: Because they don’t interrupt the person’s primary browsing session, popunders often generate more engagement and clicks than other ad formats.
Improved Visibility: Popunder ads stay visible even following the user has finished with the key site, increasing the likelihood of interaction.
Less Intrusive: Popunders are less likely to annoy users compared to pop-ups, causing higher user tolerance and engagement.
Lower Cost: Due to their low-profile nature, popunder ads typically have lower costs per click or per impression in comparison with other ad formats.
Wider Reach: Popunders work well for various forms of campaigns, including e-commerce, affiliate marketing online, app installs, and subscription-based services.

To maximize the impact of your popunder campaigns, follow these best practices:

Target the Right Audience: Use detailed targeting options like location, device type, operating system, and interests to reach the most relevant users. Precise targeting improves engagement rates and minimizes wasted impressions.

Craft Compelling Landing Pages: Since popunders open a whole new page in the shadows, ensure your landing page is optimized for engagement. Use clear calls to action, engaging visuals, plus a streamlined design to encourage conversions.

Experiment with Different Offers: Popunders perform best for campaigns that don’t depend upon immediate action, like sign-ups, surveys, downloads, and other leads generation offers. Test various offers to find the most effective one for the audience.

Leverage Retargeting: Use retargeting to interact users who previously interacted along with your site but didn’t convert. Popunder retargeting ads work well in re-engaging prospective customers and can drive more conversions.

Monitor Performance and Adjust: Regularly review your campaign analytics to find out which aspects are working and which aren’t. Adjust your targeting, budget, and bidding strategy when needed to optimize results.
