Enhanced Campaign Improvements
In April, it was announced that Enhanced Campaigns will also include social annotations where they can improve performance, without additional edits required to campaign settings. All you need to qualify is a Google+ page with at least 100 followers and a linked website that matches the URL in your ads. Social annotations display the number of Google+ followers an advertiser has under the ad text.
Although social annotations have existed for more than a year now, the main difference is that they can now show automatically and don't need to be manually set up.
Advertisers can now also reach app users, with ads in apps based on context such as location, time of day and type of device with Enhanced Campaigns. Google claims that the powerful bidding tools within Enhanced Campaigns will allow advertisers to reach the right people with the right ads, at the right time - as you can adjust bids across demographics, interests, topics and remarketing at ad group level.
