If you've gone to the trouble of creating and maintaining a LinkedIn profile, it's important to let people know you're on the site. Many contacts will find you through your professional network, but one of the best ways to promote your profile is to link to it in your email signature.
"Most people don't use that very important real estate," says Caroline Ceniza-Levine, a career expert with SixFigureStart in New York. "If you put your LinkedIn URL in your email signature, every email correspondence essentially has your resume attached."
Adding your LinkedIn profile to your signature line shouldn't set off alarm bells with your current employers either, she says, pointing out that being on the site is an expected part of being a professional these days. Just make sure not to include it on your work account. However, if an employer sees a "flurry of activity" it may raise some eyebrows, she says.
