As of 2 November 2010, LinkedIn had more than 80 million registered users, spanning more than 200 countries and territories worldwide. The site is available in English, French, German, Italian, Portuguese and Spanish.
Quantcast reports Linkedin has 21.4 million monthly unique U.S. visitors and 47.6 million globally.
The purpose of the site is to allow registered users to maintain a list of contact details of people they know and
trust in business. The people in the list are called Connections. Users can invite anyone (whether a site user or not) to become a connection.
This list of connections can then be used in a number of ways:
- A contact network is built up consisting of their direct connections, the connections of each of their connections (termed second-degree connections) and also the connections of second-degree connections (termed third-degree connections). This can be used to gain an introduction to someone a person wishes to know through a mutual, trusted contact.
- It can then be used to find jobs, people and business opportunities recommended by someone in one’s social group.
- Employers can list jobs and search for potential candidates.
- Job seekers can review the profile of hiring managers and discover which of their existing contacts can introduce them.
- Users can post their own photos and view photos of others to aid in identification.
- Users can now follow different companies and can get notification about the new joining and offers available.
Users can save (i.e. bookmark) jobs which they would like to apply for.
