Guidelines for representing your business on Google
Summary: Listings on Google My Business can only be created for businesses that either have a physical location that customers can visit, or that travel to visit customers where they are. Creating a successful listing that won’t be suspended requires avoiding prohibited content, accurately reflecting your business, and complying with the rest of the policies below.
We’ve come up with a list of guidelines for local businesses to maintain high quality information on Google. Following these guidelines helps avoid common problems, including changes to your information, or, in some cases, removal of your business information from Google.
For best results using Google My Business:
Represent your business as it’s consistently represented and recognized in the real world across signage, stationery, and other branding.
Make sure your address is accurate and precise.
Choose the fewest number of categories it takes to describe your overall core business.
Note: Brands, organizations, artists, and other online-only businesses should create a brand page instead of a Google My Business listing. Brand pages must follow the Google+ page content guidelines.
