Google has always focused on offering people the most relevant results.
Location is one important factor they used for many years to customize the information that you find. For example, if you’re searching for great restaurants, reliable chiropractor, dentist or any other service business you probably want to find ones near you, so they use location information to show you places nearby.
Yesterday Google moved the location setting to the left-hand panel of the results page to make it easier for us to see and control your preferences.
With this new display we’re still getting the same locally relevant results as before, but now it’s much easier for us to see our location setting and make changes to it.
