What’s new?

Mobile Fullpage Interstitial

We have created a new ad format called Mobile Fullpage Interstitial which shows a 900 x 1600 banner overlay on vertical mobile screens. This banner leads to a destination URL, and has a Close button on the top right.

What can this new feature do for me?

For Advertisers this ad format is high impact:

  • It covers the whole screen and gives a high CTR and viewability.
  • It provides a simple 900 x 1600 image or video banner.
  • Available at the same minimum price as popunders.

For Publishers, this ad format will reach the 95% of users that are viewing in vertical position, is secure and generates high revenue:

  • Its expected eCPM is comparable to popunder.
  • It is fully covered with a 100% fill rate.


  • This ad format shows as a fully responsive page overlay which takes 100% of the width and height of Vertical mobile screens. It is a 900 x 1600 banner which leads to a destination URL.

  • There is a small padding so that the Publisher’s site is still visible underneath.

  • It is preloaded and triggered when the user clicks on a link in the Publisher’s site and an impression is registered.

  • There is a Close button on the top right, if the user clicks on the Close button, they are redirected to the URL of the original click, in the original tab.

  • It will only show if there is an ad available.
