A new experiment from Google lets you share pages on Google+ directly from the search results. I personally haven’t seen this option yet but Berian Reed, head of search marketing AutoTrader UK spotted the ‘Share on Google +‘ after performing a search.
As you can see in the screenshot below the option is placed to the right after the URL of the search result where currently the +1 button is placed. After clicking the button you can add your own comment and choose circles before sharing on Google+.
