Best Pop-up Ad Networks for Publishers [2026]

If you run a website and want to turn your traffic into revenue, pop-up and popunder ads are still one of the fastest formats to get approved for and start earning from, no minimum traffic thresholds on most networks, same-day integration, and payouts that don’t require months of history to unlock.

But “pop-up network” covers a wide range of payout terms, fill rates, and support quality, and the difference between a good fit and a bad one is often 2-3x in actual RPM.

This guide ranks the best pop-up ad networks for publishers in 2026, starting with the one built specifically around fast approval, low payout minimums, and popunder-first monetization.

What Are Pop-up Ads (for Publishers)?

From a publisher’s side, a pop-up (or popunder) ad is a piece of code you paste into your site that opens a new browser window whenever a visitor interacts with the page, a click, a page load, sometimes a scroll trigger. The advertiser pays for that impression, and you get a cut, typically on a CPM (cost per thousand impressions) basis. Unlike display banners, pop formats don’t need dedicated ad space on your layout, which is a big part of why they’re popular with publishers who don’t want to redesign a page just to monetize it.

Most networks that sell pop formats to advertisers are also the ones publishers sign up with directly to serve that inventory, so “best pop-up ad network” is really the same list from two sides of the same marketplace: advertisers buying the traffic, and publishers supplying it.

How Publishers Earn From Pop-up and Popunder Ads

The mechanics are the same across most networks:

1. Register your site: submit your domain, wait for approval (this ranges from under an hour to a few days depending on the network)
2. Create an ad zone: configure format, frequency cap, and any targeting rules
3. Paste the script tag: into your site’s header or footer, no plugin required on most CMSs
4. Traffic gets matched to advertiser demand: in real time, via the network’s ad exchange
5. You get paid: on a CPM basis, according to the network’s payout schedule and minimum threshold

The two numbers that actually determine your income are fill rate (what percentage of your traffic gets a paying impression) and eCPM (effective revenue per thousand impressions after fill rate is factored in), a network advertising a high headline CPM with a low fill rate can pay out less than one with a modest CPM and near-100% fill.

What to Look for in a Pop-up Ad Network as a Publisher

• Minimum payout threshold: ranges from $5-$100 across networks; lower minimums mean faster access to your first payment
• Fill rate: how much of your traffic actually gets monetized rather than wasted on unfilled requests
• Payout speed and methods: daily vs. weekly vs. net-30, and whether they support PayPal, Paxum, Payoneer, crypto, or bank wire
• Approval speed: same-day approval matters if you’re testing a new site or need revenue fast
• Ad quality / anti-malware filtering: low-quality or malicious ads hurt user trust and can get your site flagged by browsers
• Format flexibility: networks that support popunder plus native, push, or banner let you diversify without adding a second network
• Support: a real account manager matters once you’re past a few hundred dollars a month in revenue

Best Pop-up Ad Networks for Publishers in 2026

1. Mondiad

Why it’s #1: Mondiad is built by the team behind PopCash, one of the original popunder networks, and it shows in how the publisher side is set up: a $10 minimum payout, daily withdrawal requests (or automatic recurring payouts), and campaign approval that runs under an hour during working hours, most of the friction that slows down other networks is stripped out. Fill rate sits close to 100% thanks to a broad global advertiser base, so very little of your traffic goes unmonetized.

Beyond popunder, Mondiad also runs push, native, banner, and interstitial formats, so you can diversify inventory without adding a second network, plus a 5% referral program (up to $1,000) for publishers who bring in others. [INSERT: real avg. eCPM by GEO / vertical from Mondiad’s publisher data]

• Minimum payout: $10
• Payout methods: PayPal, Paxum, Payoneer, Capitalist, bank wire, crypto (BTC, ETH, USDT, USDC)
• Payout speed: 24–48 hours; daily or automatic scheduling available
• Formats: Popunder, push, native, banner, interstitial
• Approval time: Under 1 hour (working hours)

2. Monetag

Monetag runs a multi-format stack (popunder, push, in-page push, vignette banner, SmartLink) with an AI optimization layer that routes each visitor to whichever format converts best, rather than locking you into one. It has one of the lowest payout minimums in the category at $5, with weekly payouts and no minimum traffic requirement, making it accessible for brand-new sites.

3. PropellerAds

PropellerAds brings a very large advertiser demand pool, which tends to translate into strong fill rates even for less common GEOs. It supports popunder alongside push, native, and interstitial, with a self-serve dashboard for managing ad zones and reporting.

4. Adsterra

Adsterra pairs popunder inventory with a dedicated Partner Care Program and 24/7 support, a meaningful advantage for publishers who want a responsive account manager rather than a ticket queue. Onboarding is fast, with site moderation typically completed in under 10 minutes.

5. HilltopAds

HilltopAds focuses specifically on popunder monetization with ad-safety filtering and quality controls designed to keep malicious or low-quality creatives off publisher sites. It’s positioned less around a single standout feature and more around consistent demand and transparent payout reporting.

6. PopAds

PopAds remains a straightforward, popunder-only option with no minimum traffic requirement, which makes it a common starting point for very new sites. Its single-format focus is also its main limitation, publishers who want to test push or native alongside popunder will need a second network.

7. Galaksion

Galaksion supports popunder, native, on-page notification, push, interstitial, and mobile push under one publisher account, backed by over a decade in the market. It vets advertisers and creatives before they go live, which is a plus for publishers concerned about ad quality.

Why Popunders Earn Publishers More Than Pop-ups

This distinction matters as much for publishers as it does for advertisers, arguably more, since it directly affects both your revenue and your site’s user experience.

That guarantees the ad gets seen, but it also means a meaningful share of visitors close it immediately, sometimes before it even finishes loading, which drags down advertiser click quality, and advertisers who see poor performance from pop-up inventory bid it down over time.

Pop-ups are also the format browsers target most aggressively with built-in blockers, which caps how much of your traffic can even be monetized this way.

The interruption happens on their terms, not yours, which means steadier click quality for advertisers, and advertisers who see better performance bid higher for that inventory over time.

Browsers are also generally less aggressive about blocking popunders than pop-ups, so more of your traffic converts into a paying impression in the first place.

That combination, better advertiser performance plus less blocker interference, is a direct explanation for why popunder eCPMs tend to hold up better than pop-up eCPMs over time, and it’s the reason Mondiad’s pop inventory is popunder-only rather than split across both formats.

Site Types That Monetize Best With Pop Traffic

Pop formats tend to perform best on sites with high page views per session and content that doesn’t require a highly “premium” ad-free feel:

• Streaming and download sites: high page-view volume, format tolerance is high
• Entertainment and meme/content aggregators: fast browsing sessions suit pop triggers well
• Blogs and niche content sites: easy to add without a layout redesign
• File-sharing and utility tools:task-completion moments are natural popunder triggers
• News and forums: steady repeat traffic, good for frequency-capped monetization
• Gaming and betting-adjacent content: where local regulations permit, this vertical tends to pay some of the highest eCPMs
