Do you check your LinkedIn analytics?
TCM Branding Quick Read
One of the great features of LinkedIn is that you can always track the level of engagement of your activity. If you are not already routinely doing this, it's good practice to incorporate doing so.
For your regular posts, you can see the overall number of views of the post right below the post. This includes the number of Likes, Comments and total Views. This provides you a gold mine of people you can possibly add to your LinkedIn network. If you have engagement from individuals who are not 1st level connections, you can view their profiles and decide if you want to send them a connection invite. This feature is very helpful for seeing the reach of your published articles as well. You can see the number of Views, Likes and Comments next to the right of your name at the top of your articles. The actual Comments are shown after your article.
