Linkedin for local SEO is kinda weird... posting alone usually just fills the profile, doesn’t really drive calls. The clients come when you get specific with who you’re talking to, like owners of dentists, med spas, roofers, etc, then leave a real comment, connect, and send something short that points out one obvious issue in their GBP or site. Broad “SEO tips” get likes, not meetings.
The bit that seems to work best is a tiny audit first, no pitch dump. If the first message feels like a sales blast, it dies there. 2nd or 3rd touch is where it starts moving, imo.
