There are two ways to use this code.

      ga.src = ('https:' == document.location.protocol  
        ? 'https://ssl' : 'http://www')  
        + '.google-analytics.com/ga.js';  
      ga.setAttribute('async', 'true');  
      document.documentElement.firstChild.appendChild(ga);  
    })();  
    </script>  
   



2. Split the code. Half of the code will be put before the </head> tag. Another half will be put at the end of the page, before the </body> tag.
   The first half (before </head> the tag).

        ? 'https://ssl' : 'http://www')  
        + '.google-analytics.com/ga.js';
