Besides that, adding a profile headline and summary would be real helpful to make an impression.
The headline gives yourself a professional ‘identity’, a front that may or may not showcase some of the more detailed parts of your profile, hidden away from viewers who are not connected to you. A summary would bring out your personality which can complement your Curriculum Vitae (CV) if an employer were to view your profile.
It’s also important to use keywords in your headline, summary and throughout your entire profile. The keywords could consist of your main passion or profession and will help your LinkedIn profile turn up more often on search engine results.
