Google Site Map
What are Sitemaps?
Sitemaps are an easy way for us to inform search engines about pages
on your site(s) that are available for crawling. In its simplest form, a Sitemap is
an XML file that lists URLs for a site along with additional metadata about each URL
(when it was last updated, how often it usually changes, and how important it is,
relative to other URLs in the site) so that search engines can more intelligently
crawl the site.
Web crawlers usually discover pages from links within the site and from other
sites. Sitemaps supplement this data to allow crawlers that support Sitemaps to
pick up all URLs in the Sitemap and learn about those URLs using the associated
metadata.
Using the Sitemap protocol does not guarantee that web pages are included
in search engines, but provides hints for web crawlers to do a better job of
crawling your site.
