Popunder Ad Network: Buy Popunder Traffic on Youtarget

How a popunder impression actually works

A visitor opens a page on a publisher's site and interacts with it: a click, a tap, a scroll. That interaction triggers a new browser tab that loads your URL and stays behind the current window. The user finishes what they were doing and finds your page when they close or switch tabs.

Technically that means two things. First, the impression is a full page view, not a placement inside someone else's layout, so you control every pixel the visitor sees. Second, the visitor arrives without having expressed interest in your offer. They did not click a banner. Your landing page has to do the work that a creative would normally do: state what is on offer in the first screen, and make the next step obvious.

What popunder traffic costs and how to read the bid

Popunder is sold per thousand impressions. The recommended CPM differs between countries by an order of magnitude, and it moves with demand, which is why those CPM values are pulled from the platform rather than typed into the page.

Bidding below the recommendation does not stop your campaign; it changes which inventory you win. At a low bid you take the impressions nobody else is bidding on, which is a legitimate strategy for a broad test and a bad one for a narrow, high-value audience.

The number that decides whether the campaign works is not CPM. It is the cost per conversion: CPM divided by the conversion rate of your landing page, per country. Two GEOs with the same CPM routinely differ by three times in cost per conversion, and you only see that after the first data comes in.

What it costs to start

Nothing is signed and nothing renews. The account runs on a balance you top up when you want to, and $50 is enough to open it, topped up by crypto, e-wallet or bank transfer.

That matters more in popunder than in most formats, because the sensible first move here is a wide, cheap test rather than a careful one. You are buying impressions at a fraction of a cent to find out whether an offer converts cold traffic at all, and that answer costs tens of dollars, not thousands.

Frequency capping and why it decides your budget

Without a cap, a small number of active users can absorb a disproportionate share of your impressions. They see the same page repeatedly, do not convert the second or third time, and the campaign reports a CPM that looks fine next to a conversion rate that does not.

A cap of one impression per user per 24 hours is a reasonable default for a test. Once you know which sources convert, raising the cap on those sources is a deliberate decision. You are paying to reach the same person again because the data says it pays.

Check the split between impressions and unique users in your statistics after the first day. If the ratio is far above your cap, the problem is the targeting, not the format.

Which verticals fit the format

Popunder rewards offers that make sense to a visitor who arrived with no context. Mobile utilities, VPN and software installs work because the value proposition fits in one sentence. Sweepstakes and lead generation work when the form asks for one action. iGaming and betting work in countries where the category is legal and the offer is recognisable.

The format struggles with anything that requires prior trust or a long consideration cycle. High-ticket B2B, insurance and finance offers that need a comparison stage usually perform better in native, where the reader arrives from a content context and is already reading.

If you are unsure, popunder is still the cheapest way to find out. A short test tells you whether the offer can convert cold traffic at all. That answer is useful regardless of which format you scale with.

Landing page requirements

Because the visitor did not click anything, the first screen has to carry the entire message. State the offer, show one action, and make the page load fast on a mid-range mobile device over a slow connection, a large part of popunder volume comes from exactly those devices.

Avoid anything that assumes context: "as we mentioned above", multi-step funnels that start with a quiz, or pages that open a second popup of their own. Do not use aggressive back-button traps either; they inflate short-term numbers and get placements blocked.

One technical detail matters more than it looks: the page must work when opened directly, without a referrer. Landing pages that redirect based on the referring URL frequently break on popunder traffic and silently lose the whole campaign.

How to launch a popunder campaign

Create a campaign, choose the popunder format and paste the URL of your landing page. Add your tracker's parameters to the URL if you use one: Youtarget passes macros for country, device, OS, browser and traffic source, which is what you will need later to cut the data.

Next set the targeting. Start with one country and one device type per campaign. Mixing several countries in a single campaign saves setup time and costs you the ability to bid differently for each of them, which is where most of the optimisation happens.

Then set the bid and the caps. Use the recommended CPM in the table above as a starting point, set a daily budget you are willing to lose entirely, and add a frequency cap. Launch, let the campaign collect enough impressions to be statistically meaningful, and only then start cutting.
