But for the rest of us, how do we help marketers, business owners, and webmasters have confidence in their data? Analytics is all about clarity. It should help you see actionable statistics clearly and quickly. However, when you have a website structure with multiple domains and subdomains - which is often the case - sometimes things can get jumbled.
For instance, you are a CMO or a Director of Marketing at the enterprise and you are responsible for the performance and ROI of a large number of web proprieties. You look at your analytics reports and you can't find your ecommerce data from site A, site B is referring traffic to itself (definitely not a good thing!), and conversion data from your marketing campaign microsite is no where to be found.
This image sums up the feeling.
No need to panic. This post aims to offer an approach to help you plan your Google Analytics accounts setup in a structured fashion to help with clarity. I hope that by following the approach and the technical steps, you will be able to collect and manage all your data, make more sense of it, and most importantly, ensure what you are reporting on, trending, dashboarding and analyzing is based on accurate data.
Solution- Create a Google Analytics account for each domain (www.a.com, www.b.com, and www.c.com)
- Customize the tracking code to link the multiple sub-domains with their main domains
- Link the third party shopping cart with the main domain and install Google Analytics tracking code in all shopping pages
- Create a rollup Google Analytics account and add its code to all domains and sub-domains

Now on to the technical stuff. If you don't enjoy javascript and regular expressions, you may stop here and ask your webmaster or technical analyst to read further :-)
The How:
I will try to illustrate the technical implementation in 10 simple steps:
1- Create a unique Google Analytics account for each domain www.a.com, www.b.com, and www.c.com and then use the account number UA-AAAAAAAA-1 in the code in step 3 and use the accounts UA-BBBBBBBB-1 for www.b.com and UA-CCCCCCCC-1 for www.c.com in the code in step 8.
2- Create a Google Analytics account for the a rollup account that will oversee all domains and sub-domains (use the GA account number UA-XXXXXXXX-1 in the code used in step 3 and 8)
3- Add the following Google Analytics tracking code to the main site (www.a.com) and its sub-domains (blog.a.com, news.a.com, images.a.com, and media.a.com)
About the following code: We have a regular pageTracker object to track activity on each particular subdomain and a rollupTracker to track activity across all subdomains and the third party checkout site. (Click here to learn more about the customizations we made to the standard Google Analytics tracking code)
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-AAAAAAAA-1");
pageTracker._setAllowHash(false);
pageTracker._setDomainName(".a.com");
pageTracker._setAllowLinker(true);
pageTracker._trackPageview();
var rollupTracker = _gat._getTracker("UA-XXXXXXXX-1");
rollupTracker._setAllowHash(false);
rollupTracker._setDomainName(".a.com");
rollupTracker._setAllowLinker(true);
rollupTracker._trackPageview();
}
catch(err) {}
</script>
4- Enable E-Commerce Reporting
Analytics Settings > Profile Settings > Edit Profile Information
5- Add the following code* to all shopping cart pages on the store site (www.mystore.com)
*Make sure to add this code to the top of the pages.
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-AAAAAAAA-1");
pageTracker._setDomainName("none");
pageTracker._setAllowLinker(true);
pageTracker._trackPageview();
var rollupTracker = _gat._getTracker("UA-XXXXXXXX-1");
rollupTracker._setDomainName("none");
rollupTracker._setAllowLinker(true);
rollupTracker._trackPageview();
}
catch(err) {}
</script>
6- Add the e-commerce tracking code to the confirmation page after the GATC.

7- Change the links to the store site (www.mystore.com) on the main site (www.a.com) to use _link as following:
If the current link looks like:
<a href="https://www.mystore.com">Buy Now</a>
Change it to:
<a href="https://www.mystore.com" onclick="pageTracker._link(this.href); return false;">Buy Now</a>
8- Repeat step number 3 for domains www.b.com and www.c.com after updating the Google Analytics account number UA-AAAAAAAA-1 and the setDomainName value.
- To view the entire code for www.b.com and its sub-domains (click here)
- To view the entire code for www.c.com (click here)
9- Create a profile for each sub-domain (only if needed)
In order to track a sub-domain (ex. blog.b.com) in its own profile, follow the following three steps:
a- Create a filter that include only traffic from Hostname=
blog.b.com
b- Create a profile and name it "Blog"
c- Apply the sub-domain filter to the new profile
10- As you might have noticed from the codes that we added so far to all pages, we added an extra Google Analytics account to track all pageviews across domains and sub-domains to one Google Analytics account. We call this account “rollup account”.
var rollupTracker = _gat._getTracker("UA-XXXXXXXX-1");
rollupTracker._trackPageview();
Since in the rollup account, we will track pages from different sites and many of these pages might share the same naming convention, I suggest that you create an advanced filter that adds the hostname to the page name to differentiate between pages with same URI.
Once you apply the filter, the upcoming data will appear as following:
Note, in the example above if we didn’t apply the “Add Hostnames” filter, all home.aspx pages will appear as one page with 2685 pageviews.
If you have been with us so far, you are now ready to conduct your analysis based on clean and much more accurate data :)
- To review each domain by itself and for deep-dive analysis, use the domain profiles
- To get an overview and to see how the business is doing across all sites, use the “Rollup Account”
