Web-usability is improving

According to a survey conducted in late 2003 by the Nielsen Norman Group, usability on the web is on the upswing.

Some results from the survey:
- The overall success rate of completing a site-specific task was 66 percent and 60 percent for web-wide tasks. This compares to an overall success rate of 40 percent in a similar survey conducted in 1997.
- For site-specific tasks, the success rates of the less- and more-experienced groups were 59 percent and 72 percent, respectively, while web-wide tasks were completed at a rate of 52 percent and 67 percent, respectively.
- Web users are being more precise in their choice of search terms. In 1994 the mean length of a search query was 1.3 word, in 1997 1.9 word, and in 2003 2.2 words.
- One area in need of improvement is site search. While 56 percent of the searches done using a popular search engine were successful, only 33 percent of searches using a specific site's search tool succeeded.
