A Google Sitemap is a very simple XML document that lists all the pages in your website, but the Google Sitemaps program is actually much more important than that. In fact, the Sitemaps program provides a little peek inside Google's mind - and it can tell you a lot about what Google thinks of your website!

Until Google Sitemaps was released in the summer of 2005, optimizing a site for Google was a guessing game at best. A website's page might be deleted from the index, and the Webmaster had no idea why. Alternatively, a site's content could be scanned, but because of the peculiarities of the algorithm, the only pages that would rank well might be the "About Us" page, or the company's press releases.
