Facebook page owners with more than 5,000 fans will soon have access to advanced post targeting options including age, gender, relationship status and education.
Page post targeting will only apply to News Feed distribution. All posts will remain visible from the page's Timeline.

The change gives page owners more control over the messages they share to different subsets of their audience.
