Yes, Facebook is a business tool

Much the same way a power company connects homes and businesses with electricity, Facebook is a "social utility" designed to facilitate connections between people as well as businesses. Accordingly, it can be highly useful as a business tool.
A Facebook Public Profile (aka a Facebook Page) is an ideal place for businesses to establish a beachhead within the social network. It is, also, one of the most overlooked.
Many companies use other parts of the platform (Groups and personal profiles, in particular) to set up a presence, but they never bother to create a Public Profile.
One possible reason may be that Facebook lists Public Profiles under the advertising category, which may lead people to believe it is a premium feature. It’s not. Businesses can set up a Public Profile at no cost.
Facebook Public Profiles, which mimic user profiles in design and function, allow users to express their support of your business by adding themselves as fans. They can write on your Wall, upload photos and videos, and join other fans in expressing opinions on topics introduced in discussion groups.
