•Server errors, even minor ones, are likely
to cause a user to leave the Web site and
look elsewhere for information or services.
•Reading speed on a computer monitor is
approximately 25 percent slower than
reading speed for hardcopy. Therefore, do not force the user to read voluminous amounts of text.
•Avoid “under construction” signs—they raise
expectations and cause an
unnecessary link that is sure to disappoint.
•Users prefer not to scroll. Important
information should be placed within the
dimensions of a typical browser window.
•Navigation menus and headbars should be
designed consistently and should be
available on all pages that are available to the user. The design should not
rely on browser functions to assist in navigation.
•Aesthetics should never supersede
•Navigation options should be obvious, even
to the casual user. The user should
have to search the screen to determine how to link to other content or services.
