What is LinkedIn?

LinkedIn is an interconnected network of experienced professionals from around the world, representing 170 industries and 200 countries. You can find, be introduced to, and collaborate with qualified professionals that you need to work with to accomplish your goals.

When you join, you create a profile that summarizes your professional expertise and accomplishments. You can then form enduring connections by inviting trusted contacts to join LinkedIn and connect to you. Your network consists of your connections, your connections’ connections, and the people they know, linking you to a vast number of qualified professionals and experts. Through your network you can:

  • Manage the information that’s publicly available about you as professional
  • Find and be introduced to potential clients, service providers, and subject experts who come recommended
  • Create and collaborate on projects, gather data, share files and solve problems
  • Be found for business opportunities and find potential partners
  • Gain new insights from discussions with likeminded professionals in private group settings
  • Discover inside connections that can help you land jobs and close deals
  • Post and distribute job listings to find the best talent for your company

 Relationships Matter

Your professional network of trusted contacts gives you an advantage in your career, and is one of your most valuable assets. LinkedIn exists to help you make better use of your professional network and help the people you trust in return.
