Google has introduced two new news story author meta-tags for Google News: syndication-source and original-source.
The original-source meta-tag will identify the news outlet that breaks a story, while syndication-source is for everyone who repeats the story.
“Each of these metatags addresses a different scenario, but for both the aim is to allow publishers to take credit for their work and give credit to other journalists .
Although these metatags are already in use by our systems, you may not notice their impact right away. We’ll need some time to observe their use “in the wild” before we can make the best use of them. But we’re hopeful that this approach will help determine original authorship, and we encourage you to take advantage of them now.”
