Google Plus + Explained

Google’s new social media effort overlays your friends, colleagues and acquaintances recommendations against your search results and allows searchers to see a stream of bookmarked material from those who you trust. It uses the concept of circles to arrange your contacts into groups allowing you to manage what you tell them, and what they tell you.

Google believes that Google Plus + will increase search traffic to those sites marked with a +, and increase direct traffic to recommended sites through people’s Google account. They have provided free tracking tools in your Google Webmaster account to monitor the impact.
