Martin Brossman has a strategy for dealing with negative posts about your business.
How do you handle a negative posting? Imagine a restaurant owner finding a bad comment on a blog where her restaurant was reviewed. It might read: “I had to wait too long for the food and the server had an attitude!” A good responsive post would be, “I regret that you had anything less then an excellent experience. We are committed to providing great food, at a fair price, with friendly service. If you are ever having a problem, just ask for me or my shift manager.” Give a simple apology, state your commitment, and provide a guideline for future problems.
