interstitial, interstitial ad

Interstitial advertisements are usually full-page ads displayed while a user is in transit from one page to another, triggered by code included in the link. CPM rates can be as high or higher than popup and popunder rates, and interstitials, due to their similarity to traditional television advertising (i.e., their resemblance to a commercial which is juxtaposed between two television shows), are often viewed as far less intrusive. The Fastclick network (see related review) has recently begun selling interstitial ads, with considerable success.
