Google will likely make Google+ increasingly useful for businesses by adding and/or integrating services, such as
- Google Places and Local Deals, making Google+ a more localized social network,
- Google Analytics, allowing you to get a better handle than Facebook Insights on what works and what fails, and
- Google Wallet, making it easier to leverage your e-shop activities and Google+ pages.
Once Google starts serving up even better value to its Google+ users, it will become another destination businesses cannot afford to ignore.
