Facebook allows anyone to create a special page on facebook.com dedicated to their business, community, brand or product. Other Facebook users can "Like", "Share" and post comments on that page.
A business Facebook page may become an effective social marketing hub. This is where you collect the fans, post updates, photos and videos, run contests, and do other creative things to grab the attention of your customers and keep them interested and engaged.
For a daily-deal site Facebook page can be used as a deals newsfeed.
