Earlier this year, Google released the specifications for a new XML-based sitemap protocol that would lay down virtual routes for its spider. Google Sitemaps is Google's experimental web crawling initiative. Sitemaps take the blindfolds off web crawlers, giving direction and making the page-indexing process a whole lot more efficient. Implementing sitemaps is a good choice if you want your website to rank higher as Google's coverage of the web grows.

Because Google indexes websites in cycles, it would previously have been normal for updated pages to be indexed after anything up to a few days. By making a Google Sitemap-formatted file available on your Web server, you will be making sure that your entire website is indexed at one go. Keep your Google Sitemap updated using Diadematus for Google or Diadematus for Google CLI, and you will be making sure that all your sites' pages are indexed regularly and in their entirety
