Google XML Sitemaps

1. Install the plugin like you always install plugins, either by uploading it via FTP or by using the "Add Plugin" function of WordPress.
2. Activate the plugin at the plugin administration page
3. If you want: Open the plugin configuration page, which is located under Settings -> XML-Sitemap and customize settings like priorities and change frequencies.
4. The plugin will automatically update your sitemap of you publish a post, so there is nothing more to do :)

遗憾，这个插件貌似不太易用，改用了Baidu Sitemap Generator
