LinkedIn has introduced a new feature that lets users endorse members of their professional networks.
The Endorsements feature is essentially another form of offering a reference on a LinkedIn profile. It also gives more credibility to skills and expertise listed on a profile in comparison to what might be listed on a paper resume. Similar features exist on other sites that depend on social connections, such as Airbnb.
The professional social network has tried to make offering endorsements as easy and painless as possible. LinkedIn already has programmed recommended endorsements on profile pages, so at a base level, all you have to do is go in and confirm them with just one click.
If you want to be really proactive, you can suggest some more skills and expertise qualities for said contact on your own. From there, LinkedIn will both e-mail you when you have received an endorsement and list who endorsed you on your profile.

LinkedIn touts that the benefits include being able to recommend the skills of contacts and while building your own online professional identity at the same time.
