OnClick (Pop-under) ads open in a background browser window without interrupting the user's main browsing session.
A user performs an action on a website such as clicking a link, button, or any interactive element. This triggers a new browser window that opens behind the current one, remaining hidden until the user closes or minimizes their main tabs. The ad becomes visible only when the user actively finishes their current session.
Key features
Ads appear behind the main browser window after user action
No creatives needed, only target URL required
Users see the ad when closing/minimizing current tabs
Key benefits
→ Guaranteed visibility: The ad opens in a full browser window, ensuring your offer is displayed prominently rather than competing with other content on the page
→ Cost-effective: Lower CPM rates compared to other premium formats, making it an efficient choice for high-volume campaigns
→ Non-intrusive experience: Pop-unders stay hidden until the user is ready to engage, resulting in a more user-friendly experience
Best practices
Use OnClick for brand awareness campaigns. Full-window visibility captures attention effectively
Scale campaigns across large traffic volumes without exhausting your budget quickly
Optimize your landing page to capture attention immediately when users view the ad
Experiment with different user actions (clicks, time on page, exit intent) to find what generates the best quality traffic for your offer
Target social browsers (Facebook, Instagram, TikTok, etc.) to reach highly engaged audiences without redirecting them away from the platform
