Google My Business
Google My Business connects Google search, maps, Google +, as well as Insights, Reviews, and Google Analytics into one convenient application. This means you can easily manage all these features in one interface and changes will update for all of Google’s services. These services allow your local business to be found more quickly and conveniently online.
This must be set up correctly and only set up one account; you can have multiple locations under that account but don’t set up more than one. I have run across people who can’t get into their account so they just start a new one.
DON’T DO THAT fixing it is a nightmare!!!
