Google My Business
To add your business details on Google local search and Google Maps you need to first create a FREE Google My Business listing here: http://business.google.com/. You will also need an existing Google account to sign in before claiming your Google business listing.
If you need to create a new Google account, go here: https://accounts.google.com/SignUpWithoutGmail.
Note: You will need to verify your business with Google, either through a phone call where they give you a pin code or they will send a postcard to the address with the special pin code that you type back in your Google My Business page.
