docs: // Use this parameter to send the full URL (document location)
  // of the page on which content resides. You can use the &dh
  // and &dp parameters to override the hostname and path + query
  // portions of the document location, accordingly. The JavaScript
  // clients determine this parameter using the concatenation
  // of the document.location.origin + document.location.pathname
  // + document.location.search browser parameters. Be sure to
  // remove any user authentication or other private information
  // from the URL if present. For 'pageview' hits, either &dl
  // or both &dh and &dp have to be specified for the hit to
  // be valid.
