We recommend that you create an buisness profile on Google. The business profile is a supplement to your website and allows you to change the information that is displayed in a Google search for your business or website. You can find instructions on how to do this here.
After you have created a business profile, we recommend that you request the ownership. If no owner is registered, anyone with a Google account can change the business's information on Google. Only as an owner you can prevent changes or correct them if necessary. Instructions on how to request ownership can be found here. Please note that it takes seven days for all functions to be activated for the new owner.
