title: Google Analytics content experiment test effect of bypassing stage in checkout process
body: <p>Struggling to find any clear instructions / examples on this, and any suggestions would be appreciated...</p>
  
  <p>I have an <code>e-commerce</code> website which includes multiple steps eg </p>
  
  <p>1) select product </p>
  
  <p>2) select upgrade option </p>
  
  <p>3) checkout, and wish to test the effect on conversions when removing step 2 (upgrade option).</p>
  
  <p>Having trawled through documentation, I think it will require the <code>server-side</code> implementation <code>route</code>, but haven't yet found a clear example I can understand best route to implementation.</p>
  
  <p>Any suggestions / links would be appreciated.</p>
