"We're undertaking an experiment called Google Sitemaps that will either fail miserably, or succeed beyond our wildest dreams..." -- Google Blog

Google Sitemaps is a new service released today - I haven't seen this mentioned on any other search engine websites yet.

The new service (at its beta stage) aims to help Google keep track of your new pages.

"Google Sitemaps is an easy way for you to help improve your coverage in the Google index. It's a collaborative crawling system that enables you to communicate directly with Google to keep us informed of all your web pages, and when you make changes to these pages."

The first step is to create the sitemap file (in XML format), this is done by using a program called Sitemap generator. After, this XML file is placed on your server and you need to "add a sitemap" when logged into the Google sitemap service and locate the sitemap file. Google will then analysis this should located any pages Googlebot can't locate.
