Pop-Under Advertising
Pop-under ads open behind the browser: discovered when users finish their session, when attention is all yours and competition is zero. AdsNetwork is the popunder ads network and pop-under traffic network built for high-volume crypto, iGaming, and affiliate campaigns, fraud-protected, publisher-verified, and priced at the lowest CPM of any format on the network.
Premium Pop-Under Formats
Three delivery types with different quality signals and CPMs.
Full browser window opens behind the active session on page load. The highest-volume delivery type on the pop-under advertising network. Best for mass reach at the lowest possible CPM, with fast-loading, direct-response landing pages that convert users who discover the window after their session ends.
Triggered by a user click anywhere on the publisher page. Click-triggered traffic is higher quality than load-triggered, the click signals active engagement rather than passive browsing. Higher CPM, measurably better post-click behaviour and lower bounce rates.
Opens your landing page in a new browser tab behind the active tab, not as a separate window. The most user-friendly pop format and the lowest close rate of the three. Users are more likely to return to a new tab than a new window, which is why tab-under consistently generates stronger post-click metrics.
What Is Pop-Under Advertising?
Pop-under advertising is a display format where a new browser window opens behind the user’s active session, appearing only after they close or minimize their current window, allowing them to discover the ad on their own terms without interrupting their experience.
Pop-under is also the most cost-efficient digital advertising format, offering the lowest CPM and high impression volume, making it ideal for crypto, iGaming, and affiliate campaigns that need scalable verified reach on AdsNetwork.
Why Brands Choose AdsNetwork Pop-Under Traffic
The reason pop-under has a reputation problem in some verticals is bad networks selling unverified traffic. Here is what we do differently.
Pop-Under Advertising for High-Growth Industries
Pop-under is for advertisers who understand traffic quality, have tested landing pages, and need volume that premium formats cannot deliver at the right price.
iGaming pop-under ads drive casino and sportsbook player acquisition at the highest volume and lowest CPM of any format. Our iGaming-verified publisher inventory ensures pop-under traffic comes from genuine gambling content audiences, not general interest inventory dressed up as gambling traffic.
Crypto pop-under advertising drives maximum awareness for exchanges, token launches, and DeFi protocols during narrow launch windows. High volume at low CPM makes pop-under the most efficient format for broad crypto audience awareness, especially in Tier 2 and Tier 3 geos where CPC-based channels are cost-prohibitive.
Performance affiliates running CPA offers in finance, nutraceuticals, and sweepstakes depend on pop-under for scale. Our pop-under traffic network provides verified pop traffic with full postback tracking, so every conversion is attributed accurately and campaign optimisation is data-driven from the first impression.
Forex brokers, CFD platforms, and financial comparison sites reach finance-active audiences at scale. Pop-under CPM rates on premium finance publisher inventory are significantly lower than search or social — with audience quality that general pop networks cannot match.
Event-driven sportsbook campaigns around football seasons, racing events, and major tournaments use pop-under for the one thing it does better than any other format: delivering high-volume impressions to sports content audiences at efficient pop-under CPM rates, at exactly the right moment in the event calendar.

Read ArticleFrequently Asked Questions
Pop-under advertising is a display format where a new browser window containing your ad opens behind the user's active session. Unlike pop-up ads that interrupt the current experience, pop-unders are discovered when the user finishes their session — reaching them at a natural transition point with full attention, after their task is complete.
In the pop-under vs pop-up comparison: pop-up ads interrupt the active session by opening in front of current content — which is why most modern browsers block them. Pop-under ads open behind the session and are discovered after it ends. Pop-unders have lower close rates, generate less user frustration, and are not blocked in the same way. For professional media buyers, pop-under is the only pop format worth running.
Pop-under CPM rates are the lowest of any display format — typically $0.50–$3.00 depending on geo, vertical, and traffic quality tier. Tier 1 markets (US, UK, DE, AU) sit toward the higher end of pop-under CPM rates. Tier 2 and Tier 3 offer significantly lower CPMs for high-volume awareness campaigns. We provide geo-specific CPM estimates before you launch.
