Google Sitemaps is an experiment in Web crawling by using Sitemaps to inform and
direct Google search crawlers. Webmasters can place a Sitemap-formatted file on
their
Web server which enables Google
crawlers to find out what pages are present and which
have recently changed, and to crawl your site accordingly. Google Sitemaps is
intended for all web site owners, from those with a single web page to companies
with millions of ever-changing pages.
