Social extensions make it possible to link your Google+ Page to your AdWords campaigns, so that all your +1s – from your page, your website, ads and search – will get tallied together.
Consumers will be able to see all the recommendations your business has received, whether they are looking at an ad, a search result or your Google+ Page, meaning your +1’s will reach not only the 40 million users of Google+, but all the people who come to Google every day.
