According to SearchEngineLand:
Google Store Views will allow people to essentially walk into the store, off of Google Street Views. So imagine you are looking at this store, and then you can click on the door to enter it, all on Google Maps. Then when you enter the store, you can walk through it.
What’s next, you can then point to a product on Google Product Views and buy it?
