What value does G+ bring to businesses that differs from Twitter, Facebook, etc?

Google+ makes it easy to learn more about how your followers' interactions on your page affect your brand, and your business. G+ pages can easily be configured with G analytics and other google applications. Google shares a big piece of cake with rivals facebook and twitter in terms of traffic and brand. Familiarity with Google applications like mail, tube and documents will enable the user to switch to google without spending much a time in understanding the social ecosystem. Products and services will be exposed to a larger group of people who are already holding a mail account with google. Additional leverage of search feature which is basic of google will help more. Google disabled Realtime Search, which displayed tweets from Twitter and some limited content from Facebook on July 4 after its contract with Twitter expired. Google had little interest in renewing the contract because it will probably integrate its own Google+ live feed into Search.
