ANSWER:
Even if Google + is not as active or as gratifying as other social circles, it’s main benefit would be for your business is the Google search engine. You will be able to control the results of relevant searches with what you put on your Google + profile. That would be great for you instead of just relying on what the search spiders will gather on their own. So what you may not directly reap on Google +, you may benefit it through relevant searches by your target audience.
