How to Handle 'Pop-under' Ads and Verification

"Pop-under" ads (ads that open in a new window behind the current one) are some of the most elusive units on the web. They are often used for high-frequency campaigns or affiliate marketing. Because they are hidden from the user until the main window is closed, they present a major challenge for automated verification.

The Elusive nature of the Pop-under

Most "Standard" screenshot tools only capture the active tab. They have no visibility into other windows or background processes.

How AdShot Pro provides Visibility into the "Backstage"

1. Multi-Window Monitoring

AdShot Pro's browser engine doesn't just "Look" at the tab; it monitors the entire browser instance. When a script triggers a window.open() event, our system flags it.

2. Auto-Focus and Capture

When a pop-under is detected, our engine can be configured to "Focus" on the new window, clear any local cookie banners, and snap the high-resolution proof before the session ends.

3. Verification of "Exit Intention"

Pop-unders are often triggered by a user's intent to leave a site. AdShot Pro can simulate these exit events (like moving the cursor outside the viewport) to ensure the pop-under is actually firing as contracted.

Building Transparency in "Grey" Ad Formats

Pop-under campaigns are often subject to "Ad-Blocker" interference. Use AdShot Pro to prove to your clients that their pop-under creative is indeed loading and active, even on sites with complex anti-popup scripts.

Summary

Don't let your ads hide in the background. Use a verification engine that sees everything happening in the browser, not just the front-and-center.
