A day or two ago while managing a brand page I bumped into an “audience” feature. I made sure the target box was set to “anyone and moved on. Then I was on a different Google+ page and noticed it again. It appears that Google+ Pages now have a new tab called “audience”.

Users 21 and older
The custom field allows brand managers several new options and country specific settings:
These are some great new features. There is no doubt in my mind that Google+ will tweak these as time goes on.
