Site Map Usability

Site Map Usability (Jakob Nielsen's Alertbox): "Despite the prevalence of good site maps these days, users don't use them very much. So why bother making a site map for your website? Because it can help users understand your site and what it offers.

I still recommend site maps because they're the only feature that gives users a true overview of everything on a site. One could argue that a site's navigation serves the same purpose. For example, some navigation offers drop-down menus that let users see the options available in each site section. But even with these menus, users can see only one section of content at a time.

A site map lets users see all available content areas on one page, and gives them instant access to those site pages. Site maps can also help users find information on a cluttered site, providing a clean, simple view of the user interface and the available content. Site maps are not a cure-all, however. No site map can fix problems inherent in a site's structure, such as poor navigational organization, poorly named sections, or poorly coordinated subsites.

If site maps required a major investment to design, they wouldn't offer sufficient ROI to be worth doing. But because all of our guidelines call for site map simplicity, making a good one doesn't require a lot of work, and it will help some of your users. More importantly, it will help users at a critical time:"
