Information Domain • The totality of information collected during the Research and Idea Generation phase. • Also known as Presentation Content
Information Objects • Any fully defined unit of information that expresses a single complete thought as perceived by the viewer. • Also known as “chunks”, each information object results in a Web page element. • Information objects are mutually exclusive and collectively exhaustive.

Design Considerations • 40% to 60% of a Web page should be white space • Average surfer views a page for under seven seconds • Web design is often best done by teams
Text Analysis • Start with Information Objects • Review text associated with the object’s source (document, form, etc.) • Discard irrelevant text
Writing Goals • Complete or Comprehensive • Accurate or Accuracy Labeled • Easy to Read • Clear • Useful To At Least One Defined Audience • Concise
Text Composition Elements • Layout • Placement of text on a Web page • Typography • Typeface • Type style • Type Size • Color • hyperlinks, legibility, mood, tone
Text Arrangement • Proximity • places similar or related items near to each other • Alignment • position relative to edges • Contrast • used to establish focal point • Repetition • repeated consistent use of design elements
Text Grouping • By location • Alphabetic • By time • By quantity
Page Formatting • Methods of screen presentation and the division of space on a page • Menus • Image maps • Frames
Hyperlinks • Intrapage Hyperlinks • Move within a page (at same URL) • Intrasite Hyperlinks • Move between information objects at same web site • Intersite (Free) Hyperlinks • Move user to other web presentations
Criteria For Intersite Links • Information on the site is complete and accurate • Relationship works to your site’s competitive advantage • Tone of site is compatible with yours • Site appeals to your expected audience • Site support your page or site goals
Linkage Evaluation • Ratio of Possible to Actual Links should be in 40% to 60% Range • Seven or Less Hyperlinks Per Page (Not including intrapage links) • One Intrapage Hyperlink Per 10-20 Lines of Text • Use Intrasite links if your pages have 150 Lines or more
