“As far as when to post to Facebook, I keep seeing studies that tout early afternoon. That’s never worked for me. It may be that more people are online and sharing then, but I think that just means I’m lost in the crowd. I find it best to post before 6:30am Pacific, or after 8:30pm. I post 2–3 times per week.
Schedule your posts in advance right on your Facebook Page”
