With recent developments in World Wide Web technology, expressiveness of web sites and web applications is starting to converge to the functionality offered by Open Hypermedia Systems. In this paper, we examine how link typing, and an appropriate link taxonomy can be used during the web site design process. Different existing approaches to link categorization are reviewed before going into closer detail to the concept of link and its properties. Finally, a useful taxonomy from a web design point of view is proposed. The presented taxonomy defines four categories of links, with a description of how each of them can be exploited to enhance the usability of the web site. Explicitly modeling the types of the links as belonging to one of these four categories during the design phase allows for better usability, multiple customized presentations, and other automatically generated enhancements to web sites (e.g. site map, in-page navigation structures, ...).
