NN/g has tested 42 users performing investment-oriented task on 20 company websites. Some of the results showed that:
- 70% of the users completed the tasks
- 35% of the users couldn’t get a copy of the company’s latest quarterly report
- 77% couldn’t find the high/low share prices for an earlier quarter
Jakob Nielsen concludes that:
- Individual investors are intimidated by overly complex IR sections and need simple summaries of financial data.
- Professional investors are using other sources of financial information and just want management’s visions about the company’s future
- Both individual and professional investors want company background information and overview of recent news
If you can afford it, NN/g offer a 121 pages report with 65 design guidelines for improving IR usability ($248).

Usability News has tested the correlation between perceived usability and aesthetics.
The results showed that when the test participant where asked to the predict usability of a site, they ranked the site with balanced colours and layout highest.
However, user satisfaction reported after the sessions were related to successful navigation more than aesthetic appearance.

According to Jakob Nielsen, only 39% of the space of web site front pages is used for areas of user interest (when including browser tool bars and borders). In a study, the following use of browser real estate was found:
• Unused: 20%
• Navigation: 20%
• Content of interest to users: 20%
• Operating system and browser overhead: 19%
• Self-promotions (ads for the site's own stuff): 9%
• Welcome, logo, tagline, and other site identifications: 5%
• Filler (useless stock art, such as "smiling ladies"): 5%
• Advertisements: 2%
I especially like the "Filler (useless stock art, such as "smiling ladies")". This is properly what others would call "graphic design" or "branding" elements.

"This exploratory study was conducted to determine whether participants used the breadcrumb trail as a navigational tool within a site. We found the overall usage of the breadcrumb in site navigation to be low. Breadcrumb users were not found to be more efficient than users who did not use the breadcrumb."

Another Jakob Nielsen Alertbox is out. This time he covers the key metrics behind recruiting test participants for usability studies (i.e. what does it take to get a warm body in to take user tests, who is doing it, what are the known problems, etc.).

Luc Carton discusses the ancient question about whether links should be blue and purple. Findings from study of 100 top American retail sites showed that only 27% of the sites still use the standard blue colour for links. Moreover, 61% of the sites do not use different colours according to whether the links have been visited or not, and only 13% of them use the colour purple for visited links.
On account of this study, Carton concludes that the blue/purple standard no longer exists, and since the main characteristic of a link isn’t the colour, but the underlining of the text, colour doesn’t matter.

UIE learned that using a web site is a progressive process, where users are inadvertently filtered out at each stage, as they work to accomplish their goal. The stages act as a sieve. At the e-commerce sites studied, 66% of the purchase-ready shoppers dropped out at various stages in the process because of bad design, inadequate information, or wrong deliveries. By understanding these stages and how they work, we can learn a lot about building better sites.
