Graphical user interface and web site evaluation tool for customizing web sites

A computer-implemented method for displaying patterns of utilization of a resource, wherein said resource includes a plurality of objects of interest, and wherein the plurality of objects of interest are linked by a navigation structure, the method comprising the steps of:

• accessing structural data regarding the navigation structure of the objects of interest in a resource, wherein said resource is a web-site;
• defining a task sequence as a predetermined sequence of accesses to one or more objects of interest of said plurality of objects of interest, wherein an object of interest is a web-page;
• accessing session data representative of one or more sessions of user interaction with the resource where a session identifies a sequence of user accesses to said one or more of said plurality of objects of interest, wherein at least one of the user accesses is to an object of interest that is not in the task sequence;
• filtering the data representative of one or more sequences of user accesses to include only a set of sessions based on a filter criteria by comparing the task sequence to the data representative of one or more sequences of user accesses;
• and
• graphically displaying a hierarchical representation of objects of interest and their navigation structure, overlaid with a representation of the filtered session usage data.
