title: facebook pixel: PageView vs. ViewContent
body: <p>Sorry if this has been asked many times but I really got confused on how to use facebook pixel.</p>
  
  <p>I have a landing page (success page) where I want to track how many users have landed to that page.</p>
  
  <p>I am confused between PageView and ViewContent.</p>
  
  <p>In my case, what should I use so I can track the pixel?</p>
