Staging your website can be extremely useful when you need to apply updates or make a change to your website but do not wish to apply that change to your live instance, staging allows you to create a copy of the existing live website and make the changes you need, once you have made all your changes on your staged website and all is successful you can use the Push To Live feature to apply any changes from the staging website to your live website.
