title: How to get insights on a Facebook fan page without user login
body: <p>I'm trying to figure out how to get the total number of comments, posts, likes and fans for any given Facebook fan page and date range using the Facebook API's.  I need to be able to do this without the user having to log into Facebook to give the app permissions.   This does seem to be possible, as this site is able to do it <a href="https://app.conversocial.com/profiler/" rel="noreferrer">https://app.conversocial.com/profiler/</a> .But I don't know how they are doing it. </p>
  
  <p>I've looked into the 'insights' fql table, but this always seems to return empty results. And I've also looked into the 'link_stats' fql table but this doesn't allow a date range to be set. </p>
  
  <p>Does anyone have any idea on how to do this?</p>
