What content should be on a CV vs. LinkedIn when applying to graduate school? I tried asking this elsewhere and got answers from people who do not know the difference between a resume and a CV. I figured academics would.

I ask this question because my LinkedIn is pretty detailed. It has a lot of the same content as my CV, except in the terrible organization enforced by LinkedIn. I figure it might be more effective to use my LinkedIn more like a resume with the highlights, pointing to my CV (which is linked) for extra details. But I'm not sure how to go about it.

For context, I am an undergraduate applying to graduate school. I have many research presentations, awards, and experiences so it is a lot of content to shove on a LinkedIn. I only included content relevant to my research or related technical experience, but it is still a lot to read.
Academics don't use LinkedIn, so it doesn't really matter what you've put there.
