Website content is best written by the owner of the business. No one will know more about the business, what customers want to know and how to address questions than the owner or operator.
This is not to say, however, that you are on your own when it comes to writing content. While you probably have all of the information needed for good quality content, you may not have it prepared in such a way that will most benefit your website.
Website content should be written for Search Engine Optimization and for User Experience. To achieve these two very important goals you and I can work together to create and refine your content.
