Be succinct. Write no more than 50 percent of the text you would have used to cover the same material in a print publication.
Research has shown that reading from computer screens is about 25 percent slower than reading from paper. Even users who don’t know about this human-factors research usually say that they feel unpleasant when reading online test. As a result, people don’t want to read a lot of text from computer screens. Therefore, you should write 50 percent less text—not just 25 percent less—because it’s not only a matter of reading speed but also a matter of feeling good. We also know that users don’t like to scroll: one more reason to keep pages short.
Because it is so painful to read text on computer screens and because the online experience seems to foster some amount of impatience, users tend not to read streams of text fully. Instead, users scan text and pick out keywords, sentences, and paragraphs to interest while skipping over those parts of the text they care less about.
The following table shows five different ways of writing the same web content for a site about tourism in Nebraska (see facing page). The table shows how much better each variation was compared with the original text, which served as the control condition in the study.
Skimming instead of reading is a fact of the Web, and it’s been confirmed by countless usability studies. Those who write for the Web must acknowledge this fact and write for scannability:
Structure articles with two, or even three, levels of headlines (a general page heading plus subheads—and sub-subheads when appropriate). Nested headings also facilitate access for visually impaired users with screen readers.
