Many folks I know just put their title in that space. I think that’s a mistake. It’s probably the most read part of your profile. Heck, they call it a headline because like a newspaper headline your goal with this text is to draw in interested parties.
At one point I’m fairly sure Linkedin called this field “Title” or sometime along those lines which is why yours may in fact be your title. As you can see they now call it Professional Headline. Why not go back and edit yours to draw in those types of individuals you would be interested in working with. Linkedin is after all a professional network.
That’s my favorite Linkedin tip, what’s yours?
