Advertising Age has a story about how Facebook is seeking 7-figure “tentpole” advertising deals, by giving members of its advisory council some peeks at new ad formats and techniques. Diageo appears to be one of those council members that is actually committed to some bigger spending. Late last week, Facebook introduced some new engagement metrics – while traffic watcher comScore has some of its own. Mathew Ingram offers his take on the challenge for Facebook to move marketers away from clicks. Gary Stein also offers some thoughts, and advises marketers to give it a try but not spend much doing so. Facebook might be better served by building comparison tools for advertisers rather than wean them from measurement techniques they’re comfortable with. Steve Rubel notes that hybrid media – publishers with some social DNA – are emerging as a force in this relatively new social advertising landscape.
