There have been some new amendments to Facebook that you may or may not be aware of.
Geolocate your status updates
Facebook now allows you to geolocate your status updates. This is a god sent for bands who want to target specific fans in the city they are touring in.
They are also telling you the level of interaction that are based on a loose number of impressions of the news item (Page Views, News Feeds or through a Fan Box Widget impression). I have crunched some numbers on the pages that I am Admin of and they range from a good interaction number of 1% to as low as 0.01%. What is everyone else getting?
Targetting Ad Units in real time
There is also a whisper that you will be able to start targeting people on words that they have in their status updates.
