The One Thing Missing From Your LinkedIn Profile

With now more than 200 million members, LinkedIn has become a social media powerhouse -- and a vehicle for many job hunters. But merely creating a profile and posting your resume on the site won't result in offers of employment suddenly flowing in.

Experts say it's important to take at least one more step -- adding a photo. "People think that when they upload their resume, they're done," says Wayne Breitbarth, a social-media trainer and consultant. By adding a head shot, you can "bring a friendly identity" to your page. LinkedIn profiles without photos signal to many recruiters that a candidate isn't as credible as someone who's taken the time to create a fuller profile, he says.
