Popunder ads with sensible frequency caps
A new tab opens behind the current page on the user's first click, so the user keeps reading while the ad waits in the background.
How popunder ads work
A popunder opens an advertiser page in a new browser tab or window behind the page the user is on. The visitor sees it only after closing or switching from your site.
Popunders do not cover your content, which is why many entertainment, download and utility sites use them. MS Ads Network applies frequency capping so the same user is not hit on every click.

Where it works best
Download and tools sites
One popunder per session adds revenue without placing banners over the tool itself.
Streaming and entertainment sites
Audiences that browse many pages per visit work well with a capped popunder.
High-traffic, low-CPM geos
Popunders often monetize traffic that display ads under-serve.
Placement tips
- Use one popunder per session or per day; more hurts returning visitors.
- Never combine popunders with misleading "fake buttons".
- Watch bounce rate and returning-user share after enabling.

FAQ
Will popunders get my site penalised by Google?
Google's guidelines focus on intrusive ads that cover content. A popunder opens behind the page, but heavy use still hurts user experience, so keep it capped.
How often will a popunder show?
It is frequency-capped per user. Contact support if you need a stricter cap for your site.
Are popunder offers safe?
Advertiser landing pages are checked against our policies, which exclude adult, gambling and crypto offers.
Can I use popunders with banners?
Yes. Many publishers combine one capped popunder with a few banner units.
