What is a Popunder Ad?

A popunder ad is an online advertisement that instead of appearing in front of the user, it opens in a new tab or browser window behind the main window the user is actively viewing.

It remains hidden until the user closes or navigates away from their active window or tab.

How Popunder Ads Work?

Popunders are used for advertising and work by combining timing, precision targeting and visibility.

They are triggered by actions such as:

  • User clicking on a CTA button or link
  • Spending a specific amount of time on a website
  • Scrolling past a certain point on a page

The delayed visibility is more likely to boost engagement because the users see it at a moment when they are less distracted.

Strategic Planning

With the right strategic planning, popunders can be used for advertising sale deals, free rewards, VPN offers or mobile applications.

Campaign Goals

Define your campaign goal (lead generation, app installs, product sales, etc) as it determines how you design your landing pages and ad creative.

Global Reach

Promote your products and services to users of different demographics and interests across the globe.
