This plugin creates a sitemap for your WordPress powered site. This is not just another XML sitemap plugin, but rather a true sitemap generator which is highly customizable from its own options page in the WordPress admin panel. Some of its features include: support for multi-level categories and pages, category/page exclusion, multiple-page generation with navigation, permalink support, choose what to display, what order to list items in, show comment counts and/or post dates, and much more.

This plugin generates a XML-Sitemap compliant sitemap of your WordPress blog. This format is supported by Ask.com, Google, YAHOO and MSN Search.

More information what XML-Sitemaps are and how they can help you to get indexed by the major search engines can be found at Sitemaps.org and the searchenginewatch blog.
