No matter how good a site's navigational tools, site visitors will not use them if the menu categories are ambiguous. Users have to know what to expect when they click on a particular menu item. If the categories are not intuitive, users will have to resort to the site's search engine, ignoring the entire structure. The Pennsylvania Medical Society site (http://www.pamedsoc.org) had been plagued with poor menu labels until it took a step back and improved them.
无论一个网站的导航工具多么出色，如果菜单类别含糊不清，网站访问者都不会使用它们。用户在点击特定菜单项时必须知道会看到什么。如果类别不直观，用户将不得不求助于该网站的搜索引擎，而忽略整个结构。宾夕法尼亚医学协会网站（http://www.pamedsoc.org）在改进菜单标签之前，一直饱受菜单标签不佳的困扰。
