It used to be the case that if you wanted a new job, you could strategically update your profile and over the next several days you would get bombarded by recruiter messages, some of which would actually be high-quality leads.

I once got a cold LinkedIn message that got me a job that I loved. When I was looking this year though it did NOT have the same results. Lots of bots and just recruiters who see a open to work and just add you out of no where with nothing. I did get help from people I actually know on LinkedIn, but other than that it was definitely not helpful in the job search.
