For small businesses, competition lurks around every corner. Google+ Business helps you stand out and connect with customers all throughout Google land. To take advantage of this service, set up a Google+ page, which can then be found via Search, Maps and Google+ Local
Setting up a Google+ page makes up a huge chunk of Google+ Business. With a Google+ page, businesses can build a following and keep customers coming back with news updates, event announcements, and special offers and discounts. And just like a regular Google+ page, business Google+ pages let you keep contacts in the loop by sharing status updates, photos, videos and links.
With a Google+ page, you can also integrate customers and followers into your marketing campaigns — they can leave ratings and reviews, use the +1 button to endorse your posts, and share your content on their Google+ pages and throughout the Web.
A Google+ page will also help your business rank on top of Google search results. This makes it easier for customers to find directions, business hours and contact information, whether they are searching on their computers or mobile devices
Why is this important?
Google + is as not popular as other social media networks, but it is a must for business. First of all Google + is connected to Google My Business, a directory service offered free by Google and connected to Google Maps. If you want that your business will show up on Google Map
Then in case of searches on Google, the first result will also show a small enriched profile on the right making for you easier to be contacted.
