I will give you Facebook Marketing Secrets

Facebook is the leading social community online. With over 300 million users, there has never been a better way to maximize your exposure, and get your message seen by a massive customer base. The greatest thing about advertising with Facebook, is the flexibility of your advertisements. You can customize your advertisements so they appear only to specific groups or segments of people based on the information contained within their profile or based on gender, location or personal preferences. For example, if your product is tailored towards single mothers, you could develop your advertisements so that they are triggered to appear only for those who have indicated that they are single mothers in their profiles, or who have demonstrated interest in similar products or services based on their personal profile, communities or groups they've joined, or other advertisements they've responded to.
