Navigation is an important aspect in designing a Web site in order to make the information easy to find, however the task of organizing and structuring information from a website can become complex as the set of information and services provided increases. The aim of this study is to investigate the effect of eight different types of menus while performing two tasks for each menu. The target for the experiment was of people aged over 40 and some experience in using the Internet. The experiment revealed that menus which presented properties more commonly found in web applications, the task completion time and number of errors was lower, during the sessions.
