Web Site Usability: A Designer's Guide

The typical user of the product may be different than the audience on the web.

Users do not think about site structure at all.

Every search for information is a new guessing game.

Navigation bars at the top and bottom did better. Users looked at the top and bottom for answers.

Need a clearer 'You Are Here' indicator for navigation.

site maps clarify where the links lead.

Many people would return to the home page upon getting lost, even if it had the same navigational links as the page they were on.

Descriptive text links were better, especially if followed by a descriptive blurb.

People pick links based on their expectations of the page the link will take them to.

Avoid ambiguous links.

Too many links on a page cause confusion. Can help people by providing redundant links (different people use different words).

Embedded links can distract people who skim. Make sure the words in the link are clear.

Make sure a site search provides clear search results and the scope of the search is clearly defined.

Websites that sell products should help users make decisions.

People skim; help the skim.

A more white page is not better - less success in finding info.

White space spreads out information and slows skimming.

Users look for the button at the bottom.

Web Usability

Animation makes it hard to concentrate.

Download time was not important. The quality of graphics has little impact on users' ability to find and process information.

Designing for surfing versus designing for information retrieval.

Liking a site is not the same as using a site successfully.

Disliking a site - usability problem.

Ask yourself what are the obstacles to the users accomplishing their goals/ What do we change to remove those obstacles?

The more readable (on a readability scale) the text, the less successful the site was for finding information.
