It seems several people have viewed this question and some might agree that it needs another answer. What you’re looking for is a LinkedIn widget that can display LinkedIn feed on your Wix website.
There’s a plugin called SociableKIT that can help you with this. You can search it in Google. It can help you add or embed LinkedIn profile posts (feed for personal LinkedIn account) and LinkedIn page posts (feed for company LinkedIn account) on your Wix website.
You can use SociableKIT’s free version if that works for you. The premium version looks so much better though.
