Why it's important
Google My Business is the search engine's free local business directory. Claiming your Google My Business listing allows you to control the business information (address, phone number, website, opening hours, etc.) and reviews that are shown in rich snippets in Google search results and on Google Maps.
Google My Business is a big local ranking factor and helps you maintain consistencies in name, address and phone (NAP) information, which is perhaps the strongest local ranking signal.
Getting it done
Signing up with Google My Business is easy: Go to https://www.google.com/business, click Start Now and enter your business information. If you have a service area, be sure to check "yes" under "I deliver goods and services to my customers at their location". When adding your name, choose the one people would use to search for you in Google. So, for example, you'd want to use UPS instead of United Parcel Service.
