While Facebook has let Facebook Page administrators target Page updates to fans for a while now, the company just extended targeting to stream updates. The service mimics the functionality provided by the new status update privacy settings first demoed by Facebook back in July. While the new privacy settings have yet to go live almost 5 months later, it appears that Facebook wants to enable granular stream publishing filters for page administrators as well.

By clicking on a new stream filter toggle that shows up next to the “Publish” button, Page administrators can select which fans they’d like to make stories visible to based on their country and language. For international brands, this is extremely valuable. We even have a French version of our site however non-French speaking users probably won’t find the content on the site valuable. With this new feature we can target our French readers.
While we have not confirmed whether or not this is a site-wide rollout, I’d expect this feature to be available for all Page administrators in a short amount of time. We’ll reach out to Facebook for more information but considering that it’s almost midnight on the west coast, I doubt we’ll hear back until tomorrow.
Update
As Jim Burnell points out in the comments, the feature has been rolled out to all Page administrators as announced via the Facebook Pages notes.
