The number one objection we hear from people about opening social media accounts is "what if someone posts negative online reviews?". At this point, your customers, clients, supporters or patients are online, and they are talking about you. The real question is "are you listening?".
Receiving that first bad review stings, I won't lie to you. Try as you may, neither you and I will please all our customers all the time. We are human, and we just plain mess it up sometimes. If we get lucky, we have a chance to fix it.
