As of Tuesday, publishers of English-language news sites indexed by Google News will be able to include them in Google's .

This means that publishers and webmasters will be able to specify through a site map the articles they want Google News to index. A site map is a file that webmasters and publishers put on their sites to guide search engines' automated Web crawlers in properly indexing their Web pages.

Webmasters and publishers will also be able to see a list of their latest articles featured on Google News, as well as a list of indexing errors made by the automated Google crawler, so that the problems can be addressed.

Previously, publishers' control over Google News' indexing was more rudimentary, limited mostly to including an instruction to prevent the crawler from accessing certain pages.

Before launching the new site map tools, the company tested them with several news organizations, said Nathan Stoll, Google News product manager. Stoll said publishers had asked for more "transparency and control" of what content is indexed specifically by Google News
