From Google, Inc.:
"The Sitemap Protocol allows you to inform search engines about URLs on your websites that are available for crawling. In its simplest form, a Sitemap that uses the Sitemap Protocol is an XML file that lists URLs for a site. The protocol was written to be highly scalable so it can accommodate sites of any size. It also enables webmasters to include additional information about each URL (when it was last updated; how often it changes; how important it is in relation to other URLs in the site) so that search engines can more intelligently crawl the site.
Sitemaps are particularly beneficial when users can’t reach all areas of a website through a browseable interface. (Generally, this is when users are unable to reach certain pages or regions of a site by following links). For example, any site where certain pages are only accessible via a search form would benefit from creating a Sitemap and submitting it to search engines.
This document describes the formats for Sitemap files and also explains where you should post your Sitemap files so that search engines can retrieve them.
Please note that the Sitemap Protocol supplements, but does not replace, the crawl-based mechanisms that search engines already use to discover URLs. By submitting a Sitemap (or Sitemaps) to a search engine, you will help that engine’s crawlers to do a better job of crawling your site.
Using this protocol does not guarantee that your webpages will be included in search indexes. (Note that using this protocol will not influence the way your pages are ranked by Google.)"
