I post consistently and get no traction. What's wrong?
Here's what I'd say. What you should work on is not trying to fix this.
It's trying to understand from your personal side what's holding you back.
Because most times it's not really a posting problem or a personal branding problem. It's a personal problem that shows up in the posting. And you have to be aware of that if you're going to be posting consistently.
You're holding something back. You're not saying the thing you actually think, because you're worried about how it lands, or who's watching, or what someone from your old job will say. So what comes out is safe, and safe is invisible.
That's not a strategy problem. No amount of hooks or posting times fixes it.
So before you go and change your content plan, ask yourself what you're not saying. That's usually the thing that would have worked.
