Online video ads may have a halo effect on the display business. That's because sites like MSNBC.com only serve video ads when they're in the "viewable" section of a page, explains Charlie Tillinghast, President and Publisher of MSNBC.com in this interview with Beet.TV. This inventory placement approach ensures brands are only billed for ads that are viewable, rather than just stuffed at the bottom of a page, as some display ads are. The upshot is click-through rates of about 1%, much higher than the industry average, Tillinghast explains to Beet.TV. The success of this selling approach may rub off on display ads, he says.
