Studies of how users read on the Web found that they do not actually read: instead, they scan the text. A study of five different writing styles found that a sample Web site scored 58% higher in measured usability when it was written concisely, 47% higher when the text was scannable, and 27% higher when it was written in an objective style instead of the promotional style used in the control condition and many current Web pages. Combining these three changes into a single site that was concise, scannable, and objective at the same time resulted in 124% higher measured usability.
