Google is extending the use of its new social sharing feature, the +1 button, to its paid advertisements.

The search giant informed AdWords users of the change through an email. Google believes by adding the +1 button to AdWords campaigns, advertisers will be able to generate more qualified.

“Think of the +1 button as a way for fans of your business to recommend what you offer, for all their friends and contacts to see,” ClickZ cites Google's email as saying.

While the +1 button already appears beside most organic search results, it will have a staggered release among ads over the next few weeks. While marketers may have to wait a bit to see whether +1 drives more relevant ad leads, those who have integrated the button onto their sites can start assessing the impact of +1 on driving relevant traffic to their sites. As Brafton reported, the company announced new analytics reporting with +1 metrics.

Google also recently launched the +1 button on a global scale. It was previously only available with English-language searches to begin with, but now +1's will appear on German, Japanese and French websites, enabling brands that target non-English speaking audiences to extend their social search marketing campaigns.

The search giant launched the +1 button in June with the intention of adding a social signal to its algorithm a layer of social recommendation to search results. Microsoft did something similar earlier this year, integrating Facebook “Like” data with searches conducted on Bing.
