The Date: Enhanced Campaigns Rollover Starts July 22
Paid search managers: mark your calendars. Buried toward the bottom of today’s announcement on ad group-level mobile bids becoming available in enhanced campaigns is this:
We will begin automatically upgrading all AdWords campaigns to enhanced campaigns starting on July 22, 2013.
The post, from group product manager, Bhanu Narasimhan, includes no other details about the transition timeline. At this point, PPC managers should expect their legacy campaigns to become enhanced campaigns on that date.
