Choose your format

Create an advertiser account and choose the matching web format. Review deposit requirements and payment fees in the dashboard before funding your account.

Set up a focused test

Prepare your landing page: it opens in a window or tab after a publisher-site interaction. Standard billing is CPM, with a minimum bid of $0.30 per 1,000 impressions. Start with one country and device segment, set your bid and budget, and submit the campaign for moderation. Delivery depends on approval, available inventory and your bid.

Measure results before scaling

Connect conversion postbacks and distinguish registrations, first deposits and repeat deposits. Compare spend and results by source before increasing the budget.

How it works

From campaign setup to measured results

  1. Click triggers your URL

    When a visitor clicks anywhere on a participating site, a new browser window opens behind the active tab and loads your landing page.

  2. Your landing page opens

    The destination opens in a browser window or tab. Visibility depends on the browser and user behaviour; measure landing visits and conversions to evaluate the traffic.

  3. Frequency capping per user

    Default 1 popunder per user / 24h. Configure 1/3/6/12/24 hours from the dashboard.

FAQ

Popunder, frequent questions

How do I buy popunder traffic on Adexium?
Create an advertiser account, add funds (the minimum deposit is $100), then create a campaign and choose Popunder. Set your countries, devices, operating system, budget and frequency cap; add your landing page and conversion tracking. The minimum CPM bid is $0.30, separate from the deposit minimum. Review registrations and deposits in your tracker before scaling.
What landing page should I use for popunder?
Use a lightweight page that matches the ad and states the offer clearly. Put the main call to action and key terms near the top, then test page variants using your conversion tracker.
Can I buy popunder traffic on CPC?
Popunder campaigns use CPM bidding, with a minimum bid of $0.30; standard CPC billing is not available for this format. If you want to optimize toward a conversion cost, self-serve Auto CPA keeps CPM billing while the bidder adjusts bids by traffic source toward your target. Fixed CPA is in beta and available on request for direct-publisher popunder inventory; it supports tracked registrations or installs, not deposits.
How do you filter fraudulent traffic?
In-house antifraud plus Kaminari, our independent verification partner, screen for bots, datacenter IPs, repeat fingerprints, and headless browsers before the impression is counted.
Can I pay per conversion (CPA)?
Two ways. Auto CPA bidding is self-serve: keep CPM billing, set a target cost per conversion, and the bidder tunes bids per traffic source to hit it. Fixed CPA pricing — you name the price of a conversion and pay only when it happens — is in beta and available on request, because it runs on direct-publisher popunder inventory only and works when the tracked event is a registration or install rather than a deposit.

How do payouts work for publishers?
Automated payouts every 3 business days. Minimum payout is $25. We pay in USDT on TON, TRC-20, BEP-20 and ERC-20. On withdrawals of $50 or more we cover the network fee, so you receive the full amount; below $50 the network fee is deducted from the payout ($3 on TRC-20, $1 on TON, BEP-20 and ERC-20). No manual approvals, no hidden fees.
What tracking and postbacks are supported?
Server-to-server (S2S) postbacks, pixel tracking, and macros for all major trackers: Voluum, Keitaro, Binom, RedTrack, BeMob. Real-time conversion reporting.
How does anti-fraud work?
Three layers, none of them a black box. Before the auction, the bidder rejects requests from iframes, datacenter ASNs, hammering IPs and malformed user-agents; proxy/VPN traffic is blocked on SSP supply and targetable by a flag on direct placements. On the click, a JavaScript challenge by Kaminari — an independent antifraud vendor — filters bots before the redirect. Daily, every placement is scored on outcomes: enough clicks with zero conversions for any advertiser, or the same email registering across accounts, and it is blocked network-wide. Confirmed fraud is refunded.
Can I whitelist or blacklist sources?
Yes — whitelist and blacklist by source ID, app ID and zone, per campaign. There is no optimizer that silently drops sources for you. If you want automation, Auto CPA re-bids per source toward your target cost per conversion and leaves the source list under your control.
Can I pay per conversion instead of CPM/CPC?
Yes, two ways. Auto CPA bidding is self-serve on every format: you set a target cost per conversion and the bidder tunes CPM/CPC bids per traffic source to hit it. CPA pricing, where you pay a fixed price per conversion and nothing otherwise, is in beta and available on request — it runs on direct-publisher In-Page Push and Popunder inventory only, so we agree the conversion event and geos with you first. Both require S2S postback conversion tracking.
