Facebook has announced that Page admins can now schedule posts and segment their delivery, keeping them off the main timeline.

As TheNextWeb describes the utility, marketers can schedule multi-step campaigns, and run segmented marketing campaigns sent via sponsorship and to only users who match your demographic requirements (e.g., a post offering 50% off all women shoes in a retailer’s Manhattan stores) - not a far cry from the Foursquare, Google and Twitter capabilities announced in recent weeks, all aimed at segmentation geotargeting.
Scheduled Page Posts

Admins can now use the Pages Graph API to a post and schedule it anywhere from 10 minutes to 6 months in the future. Admins can change the schedule time or delete an unpublished post any time up until 3 minutes before the scheduled release.

Unpublished Page Posts

Admins frequently want to create Page posts they can sponsor, but, which contain information relevant to only a segment of the Pages's audience. These stories typically contain no information relevant to the Page's identity and story. Unpublished page posts allow for posts that can be promoted as sponsored Page posts, but do not show up on the Page's timeline. Such promoted Page posts appear only in the right-hand column, not on the news feed.

Page Admin Permissions

Page admins can now assign conditional permissions to other admins, for example, giving one the permission to create ads, and another permission only to read analytics.
