We’ve recently released a new ad format: mobile interstitial. Fullscreen interactive ads will show up in a modal window over your site, instead of opening a new tab. The user can then return to your site by clicking on the close button. Log in to your publishers account to generate the new delivery code and give it a try. Also, you can see a demo of it here.
We also have more new and exciting ad formats in the works that will both improve user experience and payouts to publishers, so be sure to check back often!
If you have any questions, please contact your account manager and we will gladly help you in any way we can.
