Multiple Domain Name Tracking Google Analytics

Question

I have a website that has multiple domains attached to it. It seems the real time view only shows visits from the site setup in the actual View.

How can I get real time to show hits from all domain names?

Here is the code I am using on all my pages:

    <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','https://www.google-analytics.com/analytics.js','ga');

    ga('create', 'MY_ANALYTICS_ACCOUNT_HERE', 'auto');
    ga('send', 'pageview');

</script>

Do I need to adjust the code to track all domains? Or do I need to adjust a setting in GA itself?

Answer 1

First off, are you absolutely sure you want to track all this data in one view? Perhaps keeping the views separate might be a cleaner solution?

Have you check out the Google Analytics resource on Cross-domain tracking (https://support.google.com/analytics/answer/1034342?hl=en) already?

It explains that the initial tracking code should look like this:

ga('create', 'UA-XXXXXXX-Y', 'example-1.com');

And you should add the following code for additional domains:

ga('create', 'UA-XXXXXXX-Y', 'auto', {'allowLinker': true});
ga('require', 'linker');
ga('linker:autoLink', ['example-2.com'] );

Finally, for three or more domains that would be:

ga('linker:autoLink', ['example-2.com', 'example-3.com'] );
