Google+ Pages can interact with users who are not in their circles
Internet giant Google is testing to enable business managers give +1 pages, and share profiles of people who are not part of their circle. This means that, for example, if a person who is not a brand follower makes a negative comment on the Google+ profile, the company will have the opportunity to respond immediately comment regardless of whether the user is not a follower .
According to Google, the change would help improve the social experience between pages and personal profiles. It also notes that it is a benefit to business, specifically the comunity managers, as this will help to improve interaction with your audience.
While the new option gives you some freedom to companies, they should not forget that the messages sent to users are not too intrusive, otherwise they could classify them as unwanted or spam.
