wordpress-plugin: Google Sitemap Generator
Google Sitemaps is a relatively unkown feature allowing webmasters to control exactly how the search engine crawls their site. by setting up an XML-file in the root-directory of the website, siteowners tell Google’s bots which pages to avoid/index and how frequently to do so. Google Sitemap Generator automatically generates & refreshes the sitemap-file each time a post is added or edited on your Wordpress 2.x-blog. furthermore, the plugin allows tweaking of intervals between indexing and pings Google as soon as content on your blog is changing.
