Facebook users can provide feedback in the form of reviews for many well placed pages and business available on Facebook. Facebook has added a new feature to respond to public reviews and previously page admins could comment and like the public reviews and now they can respond to these reviews. This will help well placed page owners or business owners to respond to negative reviews and give reward to users for positive reviews.
According to Facebook this feature wouldn't be available immediately and this would take a time and roll out in next few weeks.
