An effective Web site structure enhances user experience and allows search engines to determine the subject matter and relevancy of your site. You should create a blueprint of your site before you begin your design and content creation. It is important to keep all related Web site content grouped together into categories.
For example, if your Web site is about gourmet food, you would have a cheese section, a sauce section, and a section on dry goods. Each of your categories should have unique directory and file name structures, so that when your Web site is indexed by search engines, your site demonstrates a wide breadth of content related to the subject.
By doing this, your Web site can be viewed by the search engines as an authority across various areas of gourmet food. You need to spend time working on your Web site structure. Failure to have a properly structured site can make it difficult if not impossible for search engines to properly index your Web site. Such a failure may lead search engines to omit your Web site from the search results and conclude that you are not an authority on the subject matter of your site.
