Google News indexes tens of thousands of articles a day, but not all of them are original. Publishers can now use two metatags to help us determine us which URL we should consider the original version of an article:
syndication-source indicates which URL is the canonical version of a syndicated article.
original-source indicates which URL should be credited with breaking a story. At this time, we will only be collecting usage data for this tag in order to determine its effectiveness. For now, no ranking changes will take place based on this tag.
