title: Adding information to a google analytics pageview
body: <p>I use google analytics to monitor my traffic.  For some pages, I want to record extra information beyond just the page being viewed.  For example, if someone visits a profile page I might want to also record if that profile is a celebrity.</p>
  
  <p>I don't want to artificially alter the URL for this.  Can I add data to a pageview like I can with GA events?  And of course, then I'd like to analyze traffic based on that data.</p>
