Google Rules! General thinking is that Google search engine results favour websites that use Google products like Adwords, Analytics, Google+, Google Places and the list goes on. And this means that Google + which has integrated Google Places (formerly Google Maps) and Google Reviews is an absolute must for businesses wanting to be found on the web.
Google+ is a social media site similar to Facebook and Twitter including following, posting and commenting but with more features like Google Reviews, directions and maps etc. You also have control over who you share content with by creating circles. And of course people you share content with can share with their circles as well. It is easy to share text, pictures, and video.
You can also get a Google+ page for your business. The big advantage here is that Google search results show the Google Map results at the top of the page which also links to your website and Google Reviews providing great exposure. Specific searches for a business show your address, directions, contact information and hours. This is better exposure than the Google ads that one pays for.
