Pop-Under Fraud: The Hidden Leak in Your Ad Budgets
Pop-under fraud is a deceptive advertising practice where fraudulent ads appear behind the main browser window. These ads generate fake clicks and attract low-intent users who have little to no engagement with the website.
Key Signs of Pop-Under Fraud:
High impressions but low engagement (no clicks or conversions).
Traffic spikes from low-quality placements or unknown publishers.
Ads appearing in hidden windows or background tabs.
Sudden rise in bounce rates and bot-like activity.
Pop-unders can be further exploited for cookie stuffing, allowing unauthorized tracking without the user’s knowledge. This also raises brand safety concerns when the pop-under displays content unrelated to the user’s intent or triggers without any direct user action, such as a click. We recently analyzed a campaign where pop-under traffic was unusually high, with most users coming from odd screen resolutions, a clear mismatch compared to the organic traffic trend.
