Adding Multiple GA IDs on One Domain

You may find the need to add additional (or include your own) tracking code on a website.  Using the async analytics.js GA code, here’s an example:

<!--
UA-12345496-5 ORIG
UA-72112345-1 CNVG
US-55123457-1 UNKN
-->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-12345496-5','auto');
ga('create', 'UA-72112345-1','auto', {'name': 'CNVG'});
ga('create', 'UA-55123457-1','auto', {'name': 'UNKN'});
ga('send', 'pageview');
ga('CNVG.send', 'pageview');
ga('UNKN.send', 'pageview');
</script>
