It is important for your website to appear in Google Maps because you want people to be able to find your contact details. Perhaps people already know your business, but don’t know the phone number. If you set up your website right, this location data can easily be found through search engines.
More importantly, people often do not know your business yet and are searching globally for general terms like “pizza”, “lawyer” or “broker in New York”. Google search engine results pages (SERPs) often display local maps listings based on users’ location and keyword search. That is why it’s of great importance that your business is listed there!
