Here is a tip for you when managing and posting the same content to both your personal profile and your Facebook fan page.
First go to your Fan page and post the content at that location.
Next go to your own wall and you will see your Fan Page post. – Now SHARE this post personally.
In this way it will do a couple positive things.
First – your personal friends who have not seen or liked your Fan page will see you have a fan page and access it if they like by clicking on the information you just shared.
Second – it will stop the duplicate posts in the wall of people who are both your friends and have liked your fan page.
