XML Sitemap

XML Sitemap automatically builds a sitemap for you, and optionally submits the sitemap to a number of search engines. Sitemaps are used by Google and other search engines to more efficiently crawl your content and display search results. From my reading, there is debate over how important sitemaps are at the moment, but this module makes it easy to generate them, so why not?

If you're using Drupal 6, be aware that this module is still in development and doesn't yet have a stable release. However, I'm using the development version of it and it seems to be working fine so far. The version of this module for Drupal 5 is stable.
