When a user interacts with a publisher's page, a pop or popunder opens your landing page in a separate window or tab. There is no creative to design – the user lands directly on your page – which makes pop one of the fastest ways to drive large volumes of visits.
On FroggyAds, pop is priced per visit (CPV) from $0.0001, so you can test offers at scale across many GEOs quickly and cheaply.
