Popunder
In plain English
What does Popunder mean?
An ad that opens the advertiser's page in a new window or tab behind the current one when the user clicks anywhere on a publisher site.
Pops are the cheapest traffic on the web and among the coldest: the user did not ask for the page. They suit landers that grab attention in seconds and offers with broad appeal (sweeps, dating, utilities, gambling). Priced per thousand views (CPV/CPM); fraud filtering and publisher targeting decide profitability.
