A few tips I would add as well is to make use of the additional features a company linkedin profile has to offer, specifically the "Events" listing. If you are doing live or virtual events the "Events" listing on your company profile allows you to invite and tag the speakers you have coming to your event.

It also comes down to the content you're offering. In my experience you will want to share original content more than content written by others, even if it's industry related. Blog posts have always done well for me as well as case studies and brief research posts.

I would also recommend testing animated gifs to go along with your content offers, movement in your posts can cause scrollers to pause on your post and pull them in. Video is also a great option, especially if you apply for the LinkedIn live stream.

Hope this is helpful, feel free to reach out if you have more questions or would like to talk further!
