Search Engine Optimization and Web Design are important to the survival of any business and need consistent maintenance.  In terms of SEO it is important to have constant content with useful keywords and phrases along with metadata tags, this can be an overwhelming task for business owners who have many other parts of their business to worry about.  Likewise maintaining a website can prove a daunting task with the need to add content, fix links or change out-of-date pages.  Having a freelancer on call to spot check a website or go through keyword analytics is the best solution as they can concentrate on a specific task without having the added expense of a full time employee.
