Appearing in Top Stories
“Top Stories” is a section that appears within Google Search whenever our automated systems determine that a query is particularly news-oriented and that there's relevant, high-quality news content to display.
Being in Google News does not guarantee that content will also appear in Top Stories. Content is automatically selected, if deemed relevant to show.
There's nothing special for publishers to do to be considered for this area other than to produce high-quality content and comply with Google News content policies. However, to be considered for the carousel section of Top Stories on mobile, content needs to be published in AMP format with article-specific structured data (support for other AMP-like formats will be coming in the future). The AMP Status Report in Search Console can help publishers identify content with AMP issues.
