Google Webmaster Tools recently introduced the Google News Sitemaps for news publishers who are indexed within the popular Google News service. David Stansbury of KB3KAI.com has put together a Google News Sitemaps WordPress Plugin for blogs (or sites) which use WordPress as their CMS to manage news stories.
Google announced their new Sitemaps for Google News program on November 21, 2006. I checked it out and the protocol is fairly standard and simple to follow. See the URL above for more information and technical specs.
I modified a simple, standard sitemap generator script (URL) to output a Google News sitemap feed. All you need to do is download and unzip the file (below), modify the categories keywords list (click here for a list of available categories), and upload to your main WordPress directory.
