Now I'm wondering, is GoogleBot able to find those posts automatically or does it need a little hand?!
It's probably not a very strong backlink, but if nothing else, I'd like Google to be aware of those posts of mine. I noticed that I would get backlink info from my posts here on Warrior Forum (which is probably much better than LinkedIn anyway, isn't it? :-) )
Have you seen LinkedIn backlinks in your Google Search Console?
