Your Linkedin profile is no longer an extension of your resume. At least that's not how you should look at it. It's evolved. And it's way too powerful to be taken for granted.
This is your brand. It's your long game. You are connected with people who care about what you have to say and share. And, it just so happens, that it's a super effective way to not only build trust and recognition but also do business.
Five years from now, you'll wish you had spent more time sprucing up your Linkedin to attract a specific kind of audience. You're a greater expert than you think! So share what you know and be consistent with it.
Funny thing is, optimize your Linkedin accordingly, it also ends up being way more attractive to recruiters and hiring managers—if that's something you care about right now.
