What is a Site Map?

A site map (or sitemap) is a representation of the architecture of a web site. It can be either a document in any form used as a planning tool for web design, or a web page that lists the pages on a web site, typically organized in hierarchical fashion. This helps visitors and search engine bots find pages on the site.

While some developers argue that site index is a more appropriately used term to relay page function, web visitors are used to seeing each term and generally associate both as one and the same. However, a site index is often used to mean an A-Z index that provides access to particular content, while a site map provides a general top-down view of the overall site contents.

Why do I Need a Site Map?

Site maps can improve search engine optimization of a site by making sure that all the pages can be found. This is especially important if a site uses Adobe Flash or JavaScript menus that do not include HTML links.

Most search engines will only follow a finite number of links from a page, so if a site is very large, the site map may be required so that search engines and visitors can access all content on the site.
