Setting up a GMB account is straightforward and can be done in a few steps:
Go to the Google My Business website and sign in with your Google account. Enter your business name and address. If your business does not have a physical location, you can choose to hide the address and only show the service area. Select the appropriate business category that best describes your business. Add your contact information, including phone number and website. Verify your business. Google will send a postcard with a verification code to your business address. Once you receive it, enter the code in your GMB account to complete the setup.
