With social media posts, I always want to direct people to my website, my home base, that I own and control.
This means posting a link on social media. I do that on Twitter (because there isn’t room for the full post) and on Facebook (because a link is all I have time for).
I do this on LinkedIn too, but I don’t see many other people doing that. Instead, they put their entire post on LinkedIn. But I don’t recommend that. Direct them to your website.
