sitemap or site map
A Web page included on many Web sites, its purpose is to help users navigate large, complicated sites. The sitemap usually lists text links to the content of a Web site in its entirety, on one page. For example, when you click on a nav bar link to a sitemap, you will see a hierarchical listing of the entire Web site's content; you can then click on a link to whatever content you are interested in.
