Sitemap makes it easy for administrators to tell search engines what pages they can crawl on their site. The simplest form of Sitepmap is an XML file that lists the URLs in the Web site and other metadata about each URL (the time of the last update, the frequency of changes, and how important it is relative to other sites on the site) so that search engines can crawl the site more intelligently.
Web crawlers typically look up pages through links within the site and from other sites. The Sitemap provides this data to allow the Sitemap-enabled crawler to crawl all the URLs provided by the Sitemap and to learn about URLs that use related metadata. Using the SITEMAP protocol does not guarantee that pages will be included in the search engine, but can provide some hints to web crawlers so that they crawl the site more effectively.
Sitemap 0.90 is provided in accordance with the terms of creative public authorization-shared (attribution-sharealike Creative Commons License), and is widely used by Google, Yahoo! And the support of many vendors, including Microsoft.
