There are quite a few business owners who like the idea of being able to do everything on their own. They learn a bit about the use of content management systems and they use stock templates to create their website. The problem is that many other business owners looking to save are doing the same thing. This means that the same website design is being used by hundreds if not thousands of business ventures.
This is usually going to have a very negative impact in your business if people see that same design in other sites.
