Google (XML) Sitemaps Generator for WordPress
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 about 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.
If you have questions about XML-Sitemaps or run into problems, have a look at my Sitemaps FAQ.
Note: The XML-Sitemap format was introduced in 2005 by Google and adopted in 2006 by YAHOO, Bing (formerly MSN Search) and Ask.com so thats why it’s often called "Google Sitemaps".

Installation:
Simply download the Zip-Archive and extract all files into your wp-content/plugins/ directory. Then go into your WordPress administration page, click on Plugins and activate it. After that you will have a new menu point called "Sitemap" under the "Options" menu. You can alter the default change frequencies, filename and other options there. Click once on "Rebuild Sitemap" to create your sitemap the first time. If you receive an error that the sitemap files could not be written, continue reading.
The script needs write access to your Blog directory. Check out the WordPress Codex or have a look at the FAQ for help.
Professional Support:
If you require professional support from the plugin author or sell WordPress to your clients, you can subscribe for Support & Upgrades. The professional version also includes a “white label” switch which will hide all backlinks and donation information.
