Rich Cards display as a rectangle in certain mobile search engine results pages (SERPs). The rectangle contains a carousel of cards that include a thumbnail image, a title, and other relevant information. If a user is searching for restaurants, Rich Cards will display their addresses and Google reviews. If a user searches for recipes, they might display the preparation time for each recipe included in the carousel.
Certain websites or businesses that may appear on Rich Card results must implement schema.org structured markup for their web pages, as it’s only by providing this structured data that Google will be able to make the cards.
