Your LinkedIn profile might be a digital shrine to yourself, but you can also use it to help others — and in turn attract more attention to yourself. Find students you went to school with or past coworkers and endorse them for skills you know they're good at. This not only will help them look better to potential employers, but it could also lead to traffic back to your profile. You never know: someone could be looking at an endorsement you made and then click on your name to check you out, even if they were originally looking at another person's profile. It's also just good karma to do this. Do unto others, they say, and this is the perfect opportunity to do just that.
