What are popunder ads, in plain English?
A popunder introduces a full-page destination through Pop inventory. Your landing page is the central advertising asset: it needs to explain the offer when someone arrives without a long introduction. Browser and supply conditions affect how the page opens. Avoid treating the name of the format as a promise that every visitor sees an identical window arrangement.
Pop uses full-page delivery, so the destination must explain the offer to an unfamiliar person. Prepare it with a real advertiser identity, accurate terms and an obvious next step. You are buying an audience opportunity; whether the visit becomes a useful customer action depends on the offer and the actual journey.
Keep the advertiser and publisher roles clear when learning Pop advertising. This page helps you buy traffic for an offer. Installing advertisements to earn publishing revenue is a different task with different terms. Choose the advertiser route when your goal is to send visitors to your destination, and check the relevant account requirements before funding a purchase.
Which buying terms should a beginner understand?
Learn the unit you are charged for before comparing prices. CPC means cost per click under the stated buying model; CPM means cost per thousand measured impressions. Neither number, by itself, tells you the cost of an accepted customer. Keep the campaign's actual billing unit beside the result when you review a report.
Media buying becomes easier to understand when each number has one job. The deposit funds an account, the campaign allowance limits a purchase, the bid affects auction participation and the accepted-action cost relates actual spend to useful outcomes. Read the definitions below before making a decision based on a low headline rate.
| Term | Meaning in your plan | Question to answer |
|---|---|---|
| Account deposit | Money added to fund the account under its applicable terms. | How much have you funded, and what amount will this campaign use? |
| Campaign allowance | The spending amount you authorize for a particular test. | At what limit will you review the result before buying more traffic? |
| Bid and billing unit | The offered amount and the unit used to charge eligible delivery. | Are two prices expressed in the same model and comparable conditions? |
| Recorded action | An observed visit, form, signup or order within your measurement setup. | Does this observation represent the business outcome you actually need? |
| Accepted-action cost | Actual campaign spend divided by outcomes meeting your stated acceptance rule. | Which costs, rejected actions and timing limits are excluded from the calculation? |
Write your own one-sentence plan before opening campaign settings: the offer, eligible market, destination, useful action and maximum learning allowance. Keep it next to the reports. When a setting seems attractive, ask whether changing it serves that plan. A recommendation from another provider or a published case study should be investigated in its own context, not copied as your expected result.
