Since we first launched endorsements in 2012, more than 10 billion endorsements have been shared by connections for skills ranging from leadership to machine learning. The goal of endorsements is to provide a way for your connections to recognize you for your skills and expertise. The skills and endorsements on your profile help people viewing your profile understand your strengths and help you get discovered through search. This is important, because people with at least five skills listed on their LinkedIn profile receive up to 17x more profile views.

Linkedin endorsements are now more targeted on Mobile, and soon on Desktop.
