This website appears to be organised! Amazon allows users to navigate to products through a menu of predefined topics. This approach provides for a hierarchal data structure logically following the same defined structure as the menu system. A search option and the many dynamically changing recommendations that are made provide for a user defined version of the main page. Links from the search facility this user generated page creates a web structure individual to each user. Parts of the website are sequential such as the ordering process and registering as a user. The most dominate of the structures is hierarchal with the other structures serve specific functions and build upon the underlying hierarchy.
