Google News blog: “…today we’re excited to announce a news_keywords metatag. The goal is simple: empower news writers to express their stories freely while helping Google News to properly understand and classify that content so that it’s discoverable by our wide audience of users. Similar in spirit to the plain keywords metatag, the news_keywords metatag lets publishers specify a collection of terms that apply to a news article. These words don’t need to appear anywhere within the headline or body text. Taking the Variety example above, news keywords such as “stocks”, “stock market”, or “crash” would be helpful in allowing Google News to better understand the article content for ranking without forcing the editors to water down the creativity of a great headline. Because the metatag appears only as part of the HTML code of a page, visitors to a site won’t ever see the magic under the hood.”
