Here are a few things not to do when posting to social media:

iphone1.) Never ignore your followers. When it comes to good or bad reviews and comments, acknowledge them with either an apology and desire to correct things or gratitude for the positive feedback.
2.) Never repeat post. Your followers want to see new and fresh things. It’s better to wait until you have fresh material than repost old things.
3.) Avoid offensive topics like politics, current issues, sports teams and such. Most likely you have a vast and varied  group of followers so the less you post potentially offense material, the better.
