In addition to showing users the best content from your news site, Google News also displays some of the best, most relevant posts from Google+.
The Google+ posts included in Google News can be from individual users, public figures, groups, reporters, or news organizations. Just like the articles included in Google News, posts are identified and displayed by a computer algorithm that crawls Google+ for timely and interesting content. Our algorithm looks for a variety of indications that a post is high-quality commentary on the news.
If you'd like Google News to crawl your site's Google+ posts, the first step is to create a Google+ account and start sharing public posts. Keep in mind that no human editors select which posts appear in Google News. Our team cannot provide guidance on why any given Google+ post does not appear on our homepage.
