Inside the Mind Of A Usability Expert Alaska

In order to keep Internet users at your website longer, WSM has outlined some general usability issues and their respective solutions.
  

Design Consistency:  There are few things as frustrating to end-users as inconsistent design. While unique landing pages or home pages are perfectly acceptable in the minds of most users, the remainder of a website should have the same look and feel. One way to achieve this is through the use of cascading style sheets (CSS) which enable designers to formalize font sizes and styles across an entire website.
  

Site Navigation: Site navigation is an integral part of a highly usable website. While some usability experts will tell you to link only to page related to the page a user is visiting, others recommend grouping related navigation in clusters and making all sections immediately available. Cluster grouping (most ideal for ecommerce sites) provides users one click access to every section of a site and the pages within those sections which receive the most traffic from users. This type of link grouping is easily integrated into existing designs using server side includes (SSI).
 

Search Functionality: Providing end-users with the ability to effectively search for individual pages containing information on products or services should be considered a usability priority. When search boxes or available links are easily accessible, visitors and current customers alike will use the search function to locate information you may not make immediately accessible through site navigation such as archived materials. Higher end on-site search tools also enable site owners to see what users are searching for.
