Unlike on desktop, people who do searches on their smartphones or even tablets usually need relevant answers fast. Which means less tapping. Which means seeing the right answers immediately at a glance. Google has been trying to deliver that kind of experience by turning plain search results to search results with snippets. Now it's taking another step forward by introducing Rich Cards, practically search results that visually stand out from the rest with larger preview images and larger cards with more details, to help users see the most interesting and relevant results more easily.
