Since introducing Enhanced Campaigns earlier this year, Google has regularly been conducting webinars to help advertisers get acquainted with the changes, and to help them optimize their campaigns.

Google has uploaded a new webinar specifically on optimizing mobile strategy:

This week, Google launched the Enhanced Campaigns upgrade center, which provides a tool to help you transition to the new campaigns ahead of the date (July 22) when all campaigns will be upgraded automatically.

Google also added social annotations and availability for mobile app advertisers.
