These units are full-page, interactive ad units that are placed between two pages of a participating publisher’s web pages as a user surfs the site.

“Our publishers continue to ask us for more options to monetize their sites, and we now have CPM banners, pop-unders, CPC text ads, raw clicked traffic and interstitial ad units,” said Sarah Taylor, co-founder and director of network services.

Ads for the new program can be displayed anywhere on the publishers’ websites and will include a button to skip the ad and continue viewing the publisher’s website.

“We view this as a significant incremental revenue opportunity for publishers to further monetize their existing traffic, and will be launching two more incremental revenue opportunities in the fourth quarter of 2007,” said co-founder and CEO Daniel Rand.
