Private messaging is now enabled for business pages. Fans can initiate messages to ask about products, special offers or even customer service issues. Although you cannot initiate messages, for spamming reasons, you can respond to them right from your Admin Panel when fans send them.
For those customers that have something negative to say, instead of posting their bad experience all over your wall for everyone to see they now have the option of privately discussing it with you giving you an opportunity to fix the problem. Any negative feedback can be dealt with privately. It will also make that unhappy consumer feel like you are taking that complaint seriously and personally.
Since you are now more accessible for customer inquires, product use, upcoming events, etc, customers will feel a sense of ease with using or buying from your company. This adds that personal feeling consumers love.
