LinkedIn have launched Group Statistics whereby you can view the statistics for each group that you’ve joined. I recently just left a few groups which I felt were full of spammers, feeds, no discussions or lack of engagement, lack of value and no real growth. The new stats may help marketers identify which groups they should join to get the best value from. Alternatively if you have your own corporate LinkedIn group these stats will help you understand how your group is performing and help you identify growth, target audiences, job functions etc.
Take a look at the stats for the CIMCIG group (one of which I enjoy participating in and advise all marketers within the construction industry to join):
Pretty simple hey? Look at that growth chart especially in 2011 with a 23% WoW growth! Wonder what the stats are for other popular LinkedIn groups?
