Sitemaps is a simple way for webmasters to tell search engines about various pages on their sites that are accessible for crawling. In its simplest term, a Sitemap is an XML file which lists URLs for a site all along with additional metadata about all URL (when it was finally updated, how often it typically changes, and how significant it is, relation to other URLs in the site) so that search engines like Google, Yahoo, Msn etc can more astutely crawl the site.
Web crawlers generally discover pages from links inside the site and from new sites. Sitemaps supplement this information to permit crawlers that support Sitemaps to pick up every URLs in the Sitemap and study about those URLs using the related metadata. Using the Sitemap protocol does not assurance that web pages are incorporated in search engines, but provide hints for web crawlers to do a superior job of crawling your site.
