Google+ is Google's social media network launched in 2011 with over 300 million active users. It functions similar to Facebook by allowing users to connect, share content and engage in discussions. Using Google+ can influence search results because the people and pages a user connects with on Google+ can impact how their content ranks in search results. It also provides opportunities for better content engagement through features like Hangouts on Air and communities. Determining if Google+ is right involves considering if these benefits fit your business needs and customer base.
