Good article from Business Insider showing what Recruiters look at when reviewing a LinkedIn profile via a heat map. It’s a good refresher course in keeping your profile interesting to those folks you might want to hear from if you’re engaged in a search or even just passively interested in hearing about opportunities.
Typical progression is
Picture – do you have one? Is it professional?
Status – have you updated it recently?
Current/Past employer in main area – is it properly reflected, and does it actually reveal something about other than the title?
Right side (“Send a message”, etc) – I think this is something of a reflex – there’s nothing you can enter on the right.
References – do you have any and are they relevant?
