- Design is a key determinant to building online trust with consumers. For motivated users of an information site, bad design (busy layout, small print, too much text) hurts more than good design helps. – Sillence, Briggs, Fishwick, and Harris, 2004.
Also see Stanford University’s “Guidelines for Web Credibility”.
- Layout on a web page (whitespace and advanced layout of headers, indentation, and figures) may not measurably influence performance, but it does influence satisfaction. – Chaperro, Shaikh, and Baker, 2005.
- Experience matters: Blue links are easier to click than black ones, even though black ones have higher visual contrast and are easier to see. – Van Schaik and Ling, 2003.
- It’s important to consider the users when you have a choice of icons, links, or both. Initial performance is best with the link alone. Frequent users can use either equally effectively. Icons are not faster, relative to text links alone. – Wiedenbeck, 1999.
- Rules of thumb for icons: Make them as large as feasible, place frequently used icons in a persistent task bar, and arrange them either in a square (first choice) or in a horizontal layout. – Grobelny, Karwowski, and Drury, 2005. Read more…
