Credibility and trust are longstanding journalistic values, and ones which we all regard as crucial attributes of a great news site…If a site mixes news content with affiliate, promotional, advertorial, or marketing materials (for your company or another party), we strongly recommend that you separate non-news content on a different host or directory, block it from being crawled with robots.txt, or create a Google News Sitemap for your news articles only. Otherwise, if we learn of promotional content mixed with news content, we may exclude your entire publication from Google News.
If only Google News would whack big-profit aggregators—you know, like Huffington Post, and take away their incentives to re-report and spread gossip.
