Until now, Google asked to add a three-digit numbers at the end of your web / blog contents URLs to submit contents to Google News. Now the “three-digit-number requirement is waived if you submit a Google News sitemap in order to alert our crawler to your news articles in your Blog. This tool will enable you to optimize the inclusion of your content without having to change the structure of your URLs. You can find more information about creating a News sitemap in our Publisher Help Center.”
