Embracing Mobile Search
On mobile, a card is the basic presentation unit of a search result. Rich results are the search results that have extra information attached to it, this could be aggregate ratings, prices or availability. The end result is a well-structured presentation that is easy to grasp and quick to act upon. Another type of rich result offers a direct interaction with the search result. For instance, some restaurants now offer the possibility to reserve a table directly from the search result. In the future, there will be even more interaction possible, thus making for a much more user-friendly and efficient search experience.
Cards have a higher image resolution and visual appeal to it, aimed at improving the web search and browsing experience of the user, creating a visual appeal to your product and service.
