Popunder is the oldest performance format on the open web and still the cheapest way to buy volume in 2026. It’s also the easiest place to burn a budget, because low CPMs hide wide swings in traffic quality. Picking a pop network is less about who has the biggest number on their homepage and more about four things you can actually measure. Here’s how to read the market, and where Adexium fits — including where it doesn’t.
What popunder actually is
A popunder opens your landing page in a new tab or window behind the one the user is on. They see it when they close or switch tabs. It’s sold on CPM (cost per thousand impressions), carries no creative to design — the landing page is the ad — and delivers the highest raw volume of any format. That makes it the default for single-decision, high-volume offers: sweepstakes, casino, crypto, dating, VPN, utilities, and app installs.
Because there’s no creative and the format is cheap, pop traffic attracts both real users and a lot of noise. The whole game is separating the two.
The four things that actually decide a pop network
Ignore the homepage impression counts. Judge on these:
1. Volume in your GEOs. A network with 5 billion daily impressions is useless if 90% of it is in three countries you don’t run. Ask for volume in your specific targets — Tier-1, LATAM, SEA, CIS — not the global total.
2. Real price, after the auction. The floor CPM and the price you actually clear at differ. On self-serve networks you set a bid; what matters is the delivered CPM at the volume you need. Adexium’s popunder floor starts at $0.30 CPM, but like any auction the clearing price rises with competition in premium GEOs.
3. Traffic quality and fraud filtering. This is where pop budgets die. A good network runs bot filtering, proxy detection, and click/impression validation before it charges you. A network that sells you unfiltered pop volume at a great CPM is selling you nothing. Ask what antifraud runs on the traffic — Adexium filters through its Kaminari/Aegis pipeline and validates clicks before billing.
4. The conversion you pay on. Most pop networks bill CPM and leave optimization entirely to you. Networks with CPA or target-CPA (Auto CPA) bidding shift some delivery risk toward the conversion — a meaningful difference on a format this noisy.
The comparison, by approach
| Approach | Volume | Pricing | Fraud filtering | Pay-per-conversion |
|---|---|---|---|---|
| Adexium | Web pops plus Telegram Mini App / bot inventory | From $0.30 CPM, auction | Kaminari/Aegis pre-bill validation | Yes — CPA + Auto CPA |
| Established pop networks | Very large web-only footprints | CPM, auction | Varies by network | Often CPM/CPC only |
| SSP resellers | Aggregated third-party supply | Cheapest, most variable | Depends entirely on the source | Rarely |
Established web pop networks have years of scale, and for pure Tier-1 volume they’re a sensible first stop. What Adexium adds is conversion-based bidding and Telegram inventory on the same self-serve account, plus antifraud that runs before you’re billed — useful precisely because pop traffic is the format most exposed to junk.
Practical tips that save budget
- Frequency cap from day one — one or two impressions per user per day. Uncapped pops burn budget on the same users.
- Whitelist, don’t just blacklist. Start broad, find the sources and placements that convert, then concentrate spend there.
- Use a prelander for anything but the most direct offer — pops are cold, and a prelander warms the click.
- Judge on the deposit/sale, not the visit. Pop volume makes registrations cheap and meaningless; measure the paid event.
Where Adexium is the wrong choice
- You need only the absolute largest Tier-1 web pop pool and already run a network that delivers it — a second source may not beat it on raw volume.
- You want a managed/done-for-you buy — Adexium is self-serve.
- Your offer is licensed brand advertising in a regulated market — a compliant DSP fits better than any pop network.
Adexium fits best when you want cheap pop volume with conversion bidding and antifraud built in, a low $100 entry to test, and Telegram inventory alongside the web.
How to choose in one minute
- Ask for volume in your GEOs, not the global number.
- Ask what antifraud runs before billing — if the answer is vague, walk.
- Prefer CPA / Auto CPA over pure CPM on a format this noisy.
- Cap frequency, use a prelander, measure on the paid event.
FAQ
How much does popunder traffic cost in 2026? It’s the cheapest format — floors start around $0.30 CPM (Adexium’s floor) and clear higher in competitive Tier-1 GEOs. The real cost is quality: cheap unfiltered pops waste more than they save.
Is popunder traffic full of bots? Pop is the format most exposed to invalid traffic, which is why fraud filtering matters more here than anywhere. Networks that validate clicks and impressions before billing (Adexium filters through Kaminari/Aegis) give you a cleaner base to optimize on.
Popunder or push for my offer? Popunder for cold volume and single-decision offers; push for retargeting and time-sensitive offers. Many buyers run both.
What’s the minimum to test? On self-serve networks, low — Adexium starts at $100. Cap frequency, run one GEO, and judge on deposits or sales.
Adexium is a self-serve, multi-format performance network — popunder from $0.30 CPM, plus push, in-page, and Telegram Mini App / bot inventory — with CPA and Auto CPA bidding and antifraud before billing. Start a campaign.
