Linkedin is a professional networking tool that facilitates job searching and maintaining connections. It allows users to create a public profile highlighting their experience, education, and skills to be searched by potential employers, recruiters, colleagues and connections. The document recommends users fully populate their profile, build their network by connecting with associations and groups relevant to their industry or career goals, and utilize their growing network to search for potential opportunities, both posted and unposted jobs. Networking, maintaining visibility online, and helping others in your network are key strategies for leveraging Linkedin's professional social platform.
