We've already configured WP to automatically notify the major blog search engines each time you update or publish content. Wouldn't it be nice to do the same for the major search engines such as Google, Bing, Ask.com, and Yahoo? The same XML technology can be used to create a sitemap, or a list of pages on your site available to users and crawlers. The good news is that you can leverage a WP plugin to do so with a few clicks. The Google XML Sitemaps plugin is authored by Arne Brachhold <http://www.arnebrachhold.de/>, the homepage is: http://www.arnebrachhold.de/redir/sitemap-home/*
