1. Select "Edit" at the bottom of your screen
A new row of icons will appear when you do. There's one icon for every section on your website, and every section can be edited.
2. Choose the icon labeled "Location"
Not every website has a location section, but most do. Typically you'll see it near the end of the row, beside the Footer icon.
If you don't see it, choose the "Add" icon instead, and create a new location section with just a click.
3. Select the "Address" icon
In the field that appears you can either write an address, where customers can find your physical business, or a general area, like the name of your city and region.
