I may have misunderstood, but if you're interested in pages rather than profiles you can do the following:
SocialMediaData[{"Facebook", "mathematica"}, "Properties"]
For instance we can see how busy my colleagues are updating the official Wolfram Research facebook page with the following:
SocialMediaData[{"Facebook","mathematica"}, "ActivityWeeklyDistribution", "FormattedData"]

As Sean says you will get more from directly using the various APIs Facebook makes available.
