Linkedin has been quietly adding analytics to the platform since the end of April, but the change is now official.
What this essentially means, is that as well as knowing who has viewed your profile, you can now see who has viewed your individual posts in the last six months. At the moment, it's only really able to provide you with information on the logged-in visitors, but this will hopefully change in time.
It's a natural move for Linkedin, which has been increasingly focusing on its publishing tools: a good way to get users to stay on its website a little longer.
More practically, writers regularly using Linkedin to publish their articles will have a better way of finding out which of their posts are making the most impact. A good way to refine your content writing and publishing strategy.
