title: can google analytics tell me http referrer for each specific goal conversion?
body: <p>I have a website that allows people to create an account (that is the conversion I wish to track).</p>
  
  <p>I wish to know where a specific person is coming from.  I have google analytics installed and have set up the registration page as a goal, but the reporting tells me traffic sources as an aggregated pie chart.  It doesn't report down to the user account level to say that 'person with email xyz' came from 'facebook' for example.</p>
  
  <p>What custom variables or mark up would I need to add to GA to report at that detailed level, if that is at all possible?</p>
  
  <p>Otherwise, I will just have to record the first http_referer in a cookie and stick it in a database during the registration process.  </p>
  
  <p>Any advice?</p>
