It means how far is each potential search result from the location term used in a search?
If a user doesn't specify a location in their search, Google will calculate distance based on what’s known about their location.
Think of it as where you are standing. When you do a mobile search for ~ Starbucks, you will get the nearest three Starbucks based on the "crow-flies" distance.
Or, do a search for "dentist near me". You will again get the nearest three dentists. However, drive east 4 miles, and do the same search again. You will see that you get a different set of three dentists.
