While I agree with the sentiment of the article it’s very social Selling circa 2016. 

The article is 100% in saying you need a great Linkedin profile.  But the suggestions put forward are great examples of bad practice not best practice. 

The reason for it is simple, your title is your “why” and not your “what”. It is supposed to create intrigue and your prospect will read further. 

If, as a prospect, they have 20 minutes to evaluate various competitors, then you want the person to spend 15 minutes on your profile and less time on the competitors. 

These suggestions will make the reader move on to the competition.  That isn't what you want.  The world has moved on since 2016, we are all older, wiser and the world of the internet, social and mobile has moved on.
