In this article I will do my best to describe marketing strategies that work.
So What Works?

1. Build quality relationships with people first.
   
2. Provide massive value and add quality content.
   (this includes setting up your profile, adding applications, sharing on your wall, groups and pages)

4. Engage with your friends, fans and members on a consistent basis

6. Number one most important strategy is to provide massive value.
   You may ask how can I do this?

What are some things I can do to provide this value to people? Here are some things I do to add Value.
I post motivational quotes everyday.
I get these quotes off of sites like brainy quotes

1. look for training videos on U tube relevant to my field or niche, and post these on Facebook
2. Sometimes I share a link to a good free traffic source or a product that I like.
   I do this sparingly because no one likes to be consistently sent links.
   
3. other idea is to send out tips of the day.
   

By doing these things you will build a reputation for adding quality information.
When you provide massive value on a consistent basis your content will be shared throughout the Facebook community and people will find you and want to know more about what you do.
This is a concept called attraction marketing ALERT!!! Do not make the mistake of posting hundreds of your links all over your wall or especially on other peoples profiles, groups or pages.
