Although Google Plus and LinkedIn drive the fewest social referrals, they bring in some of the best visitors: Google Plus users, on average, find themselves spending north of three minutes diving into things shared by connections in their circles. They also visit 2.45 pages during each visit, and bounce only 50.63 percent of the time. LinkedIn users generally spend 2 minutes and 13 seconds on each link they click, viewing 2.23 pages with each visit and bouncing 51.28 percent of the time. Although many sites see minimal traffic from both Google Plus and LinkedIn, now may be the time to invest in building communities within those networks if engagement really matters to your business.
