Google is testing floating “map” and “list” buttons in restaurants’ local finder on mobile.
The test makes the buttons more prominent than the usual “map” and “list” labels at the top of the screen.
Here are the floating button test screenshots next to the regular-label local finder screenshots:
Restaurants are the only type of business that has large slider images in local finder, and they are also the only type that does not have a map there. Because, perhaps, many people want to be able to see a place on the map before making a decision where to go, making the map link more prominent makes sense.
