Take advantage of the new LinkedIn page design

LinkedIn profile pages will be undergoing changes within the next few days. Before your page gets its makeover, you may want to give it a quick update.

• Update the headline: Tell people what you really want them to know about your skillset. Your title often does not accurately describe your talents. So instead of "Account Manager" write "Accomplished Sales Professional." That description gives a more accurate view of what you do to someone you're never met.
• Slim down older job descriptions: Just like a resume, you must treat more recent experience as more relevant than experiences you had ten years ago. YES, it's great that you were the editor of your college newspaper before the internet was even invented, but are those cutting table skills still relevant? Answer: Not so much.
• Post a new photo: Update your photo so that when you run into contacts, they actually recognize you. I know that Glamour Shots snap of you is your favorite, but normal people don't pose with their hand in front of their chin.
• Use the "Share an update" feature to appear in your contacts' news stream. And make comments on other people's updates. 

LinkedIn is particularily helpful for keeping in touch with professional contacts, but can be used much more proactively with just a little bit of attention. Log on to your profile once in a while and manage your public image. It's one of the most prominent things that people will find when they search for you on Google.
