Clarification: The headline of a story (“Facebook Exchange Adopts Ad
Verification, Intent Retargeting”) in in the Oct. 16 issue of Online Media Daily inaccurately implied Facebook is adopting an ad verification system, which it is not. The story reported that
third-party ad companies have begun using search intent data to support Facebook ad targeting, and use Facebook's always visible floating ad model to verify “viewability” in the
iFrame.
