title: How to count clicks on pinterest's 'Pin it' button?
body: <p>I want to count the clicks on a pinterest <code>Pin It</code> button in my shop.</p>
  
  <p>I am not interested in counting actual pins, just the clicks on the button.</p>
  
  <p>Is there any way to do this, given that the button is loaded into an iframe?</p>
