If you're writing a "round-up" article, or summarizing multiple posts, you can use structured data to make your Google search results eligible for a list-like carousel display. See this Google guide for more information.
This plugin allows you to generate the necessary markup using a simple shortcode and including a list of post IDs. Example: [itemlist_markup ids="123,456"]
If you have Shortcode UI installed and are using the Classic editor, you'll get a full user interface for inserting the shortcode.
