Google Sitemaps

Google Sitemaps is a new free service that allows webmasters and marketers to submit XML feeds of the URLs they would like Google to index and how often the content is refreshed and in need of a new crawl. This will go a long way towards getting more of your sites into the Google index and keeping them updated. Some basic reporting will be provided such as when you last submitted a Sitemap and when Google last fetched it. Search Engine Watch has a great interview with Shiva Shivakumar, Google's technical lead on the project.
