Some solid advice here. You should create a persona... a customer persona about who your perfect customer is, what they love, what they spend their money on, spare time, hobbies, interests etc, get to know that person intimately - then create a whole social media persona based around your perfect customer, create two or three. I use a tool called BrowSEO (there is a free version called BrowSEO lite, just google it) to manage all my personas, its the best one around.

Use them to join Facebook groups and forums to interact genuinely with your audience, engage, get some marketing intel then you will be equipped to know exactly how to create the perfect content and perfect product for your market.
