Targeting data is threatened by new privacy constraints, so 99% of marketers are working to replace it, says this Forrester study for data verification vendor SheerID. Most (85%) see “zero party” data (data that customers share voluntarily, such as survey responses) as critical for effective personalized experiences, but 36% worry that customer answers are not always accurate.  Adding to the challenge: 42% of marketers have access to zero-party data but don’t know how to use it effectively.

Procrastinators of the world can throw a party whenever they get around to it: Google has once more pushed back complete third-party cookie deprecation.  The new target is “early next year.” Reasons for the delay include concerns expressed by U.K. data regulator Information Commissioner’s Office, an ongoing inquiry by the U.K. Competition and Markets Authority, and widespread discontent in the advertising ecosystem.
