also another interesting thing I found,
Linkedin has a newer feature, where you can contribute to articles, so they ask things like contribute to this article "How can we improve teamwork"
I've been doing this, I think this raises your profile a bit, you are seen to be interacting and contributing, plus a lot of this can be seen as interviewing type questions.
So recruiters can see you contributing and talking about your job..
I had a recruiter reach out to me for a role, I still didnt pay for premium
