I came across an interesting article today. Surprisingly, and in my opinion, absolutely against the logic of the network, sharing a post or an article has much lower effect than a plain comment or like.
John Espirian, a LinkedIn Expert says ....."Liking and commenting is much better for LinkedIn engagement
Most people think that using LinkedIn’s Share button is a good way to spread the word about posts they like or find useful.
But LinkedIn shares don’t receive many views.
In fact, sharing a LinkedIn post is about the worst way for you to help it succeed.
A much better approach is to click the Like button and add a meaty comment."
