Rich Cards are a feature offered by Google, building on the success of Rich Snippets. They display content in a more engaging visual format, allowing for a better mobile experience on search result pages.
At the time of writing, Rich Cards are available for Recipe and Video content only.
JSON-LD for SEO does support Rich Cards – however, it does require you to use an additional (free) tool called a Metafield Tool to manually add the additional data required by Rich Cards to your article or products.
This article will show you how to setup Rich Cards for Recipes.
