A rapidly growing segment of the Internet is e-commerce. The future of economic competitiveness for most enterprises relies on entrance and active participation in the ecommerce market. About a third of the time users fail when they try to purchase products on an e-commerce site. An essential problem with e-commerce is that the controls and organization are different for each site. There is no standard way of building the navigation of the e-commerce site. Most sites do not have a global navigation system and the local one may be confusing, like solving a maze. The objective of this study is to provide an implementation method by which an agent of the artificial intelligence (AI) user interface creates a standard navigation menu to increase the usability of e-commerce. The selected menu items of the ecommerce standard user interface are based on a study of the graphical user interface (GUI) used in Windows environment and an evaluation of one hundred and two (102) e-commerce sites. The ideal standard navigation menu, E-menu, could cross over entire e-commerce sites in the World Wide Web (WWW) environment. The E-menu system considers the global level, which is simply to say “buy-your-stuff-and-leave” by clicking on a very straightforward navigation standard menu.
