What is a Marketing Consultant?

I'm often asked, what it is that I do or why do I need a marketing consultant? The truth is that not all marketing consultants are the same and each individual will have a different approach on how they handle their clients. If I had to give one general answer to the question as to, what is a marketing consultant, I would say that a marketing consultant is a person that can help develop a strategy for a business and the key being that the consultant asks the questions that are not being asked.
