Popunder Ads Explained: How They Work and When They Make Sense
By Adsonmarket Editorial Team ·
A popunder opens a new window behind the current one, so the visitor sees it when they finish browsing. It delivers huge volume at low cost — and demands care.
How they work
Triggered by a click on the page, the ad opens in a background tab with a full landing page.
Pros and cons
Large volume and full-page attention, but lower intent and possible annoyance.
Best uses
Simple offers with fast-loading landing pages.
- App installs
- Sweepstakes and sign-ups
- Broad consumer products
Example
Frequency capping
An advertiser capped popunders at one per user per day. Volume dropped 30%, but conversion rate doubled.
