When people perform a location-specific search in Google (or Google Maps), the search results they are shown include a map with markers to indicate where businesses included in the search results are located. You can list your business for free in Google Maps at Google Places for Business.
First you will need to sign in to Google using a Google account. If you don’t already have an account, you can sign up for one using the link near the top of the Google Places for Business log in page.
You will then enter the information you want included about your business – this includes contact details, a description, category, and, of course, your address. You can even add photos (e.g. your logo, a photo of your premises…) and videos.
When you have submitted your information, Google will then need to validate your listing. They do that by sending you a postcard to the address you specified for your business. The postcard will include activation instructions.
