LinkedIn is a social networking site for the business community and the world's largest professional network. It was founded in 2002 to allow members to establish professional networks of people they know and trust. Users can build their professional profile by adding details like their current position, education, skills, and connections to other professionals. Maintaining a complete profile with a photo increases the likelihood of being found in searches. Users can also follow companies, join groups in their industry, and find potential jobs and business opportunities through their growing LinkedIn network.
