Utility of a Flat Directory Structure

The site's directory structure should be flat, horizontal, rather than vertical deep down in the directory structure. The flat ones are easy to reach by the Search Engine. Obviously, the search engine takes time to reach the pages deep down. The page that contains the link directory should be up front. One such example is the following URL where google.html is six level down.

A page that deep is not generally inspected. The page ranking also goes down. Why people organize things that deep? Because one finds it difficult to organize things logically in a horizontal manner. In cases when it has to be a vertical structure one should strategically place a sitemap built by Free Online Sitemap Generator.
