What are Popunder Ads?
Popunder ads are a type of advertisement that opens in a new browser window behind the main window. In ad networks, these are used to increase user visibility without interrupting the current browsing experience. Since users see the pop-up after closing their active tab, it often gets more attention and longer exposure. Ad networks that offer popunder inventory typically monetize these ads based on views (CPM) or clicks (CPC).
They’re popular with publishers because they can deliver high revenue, but they may also be blocked by browsers or considered intrusive. Advertisers use them for promoting high-payout offers like downloads, adult content, or financial services due to their aggressive visibility and ability to bypass ad blindness compared to traditional banners.
