A site map rsp. sitemap, or less commonly: site overview is the complete hierarchical and structured representation of all individual documents (websites) in a web presence or website (page structure). Ideally, the site map also shows the hierarchical link structure of the sites.

A site map is provided by a website operator in order to give visitors an overview of the scope and structure of the website. In very extensive sites, the site map may not be able to display all individual documents, and must be restricted to representing the hierarchical structure.
