title: Best way to exclude traffic from homepage to app?
body: <p>I need to set up a filter (or segment) that excludes web app traffic.</p>
  
  <p>On our site we have a button on the top right that takes the visitor to portal.domain.com which is where the web app is hosted.</p>
  
  <p>I need a GA view that shows me traffic in which they have not clicked this button and gone on to use the web app.</p>
  
  <p>Whats the best way of setting this up?</p>
  
  <p>Thanks</p>
