There are many ways to gauge the strength of a social network: users, page views, monthly active users and time spent per page are all effective. One that I like to look at is referrals, which look at how often a social network is sourcing a link to great content. For instance, if a blog post goes viral and gets 100,000 views overnight, it’s interesting to look at the breakdown and see where all the viewers came from. Netmarketshare is a company that tracks this type of data, and their November outlook has revealed that Google+ is losing its power to refer content.
