You can create a secondary profile for each language you wish your profile to be displayed in. Viewers will see your profile in the language they're using on the site. If they're using the site in a language that you haven't created a secondary profile for, they'll see your profile in the language that is your default profile. It's not possible to make a secondary profile your default profile.
All of your language profiles will appear in search engine results on and off LinkedIn and can be accessed directly with a unique URL.
