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>
