Web Content - Organization
Limit page information only to that which is needed by users while on that page.
Do not overload pages or interactions with extraneous information. Displaying too much information may confuse users and hinder assimilation of needed information. Allow users to remain focused on the desired task by excluding information that task analysis and usability testing indicates is not relevant to their current task. When user information requirements cannot be precisely anticipated by the designer, allow users to tailor displays online.
An example of extraneous information. In this case, the user is looking for a weather forecast for Manchester, United Kingdom. The site provides this information, but also indicates tonight's vacation weather for Prague-this information is extraneous to the users original task.
