Google+ Local

Google+ Local is one of Google’s services. It emerged from Google Places. Companies can use this service to submit their location to Google Maps and make it easier for users to find them.¹⁾

SERPs have a map at the top that displays search-related businesses in the user's proximity. The company’s website will be linked right next to that map.

Submissions to Google+ Local are free. Companies use it to add their website URL, their opening hours and pictures (e.g. of products).

Since this service is connected to Google+, it enables companies to interact directly with customers and improve their website's popularity.
