We want to include our news into Google News, and now performing research how to properly do this. At the moment we have the same base URL for news and non-news articles (analysis, interviews, etc.), e.g.
I read official documentation about Getting into Google News but it's still not clear if we need to post all non-news articles under different base URL , or we can create Google News Sitemap and give there info about news. In favor of having just a news sitemap also says this article (option 3).
From development point of view, I would prefer to give authors possibility to mark articles as "news" and export them to news sitemap. This seems better, than rewriting logic for routing, rebuilding menu and making sure that old links didn't break.
So, the question is, in order to be included into Google News, is it safe to keep news and non-news articles under the same base URL , and just create a news sitemap?
