When you have lots of information, organizing it into related groups can help users navigate it all. When a group is connected to a specific action, use a tile to make that fact clear to users.
Tile actions can lead users to the next step in a flow, select something on the page or break the flow with a popover or external link. The actions involve the tile as a whole, so make sure to group the information logically. If you want to group static content without any actions, use a card.
