I am getting to the stage where I want to implement Google Analytics and see just how much traffic I am getting on my new website.  I went to Google Analytics and started my account and started the process of getting my script to add to my site.

At this point I was thinking about having to make different profiles for each of my subdomains.  I thought about it and I didn't like that idea.  I would end up getting referrals from my own domains, and that would mess up my stats a fair bit.

Well I did what I always do when posed with an issue I am not sure how to solve.  I went to Google and did a search.  I came up with a very good site and post to help me through.  I found that I just had to add one line of script to my Google Analytics code and all would be good.

<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">
var pageTracker = _gat._getTracker("UA-XXXXXX-X");
pageTracker._setDomainName("domain.com");
pageTracker._initData();
pageTracker._trackPageview();
</script>

Notice the part of the code in bold.  pageTracker._setDomainName("domain.com");

Just change out the domain.com to match your domain and you are good to go.  Above is the simple solution, but for a very cool explanation go to the Google Analytics "Unofficial" Blog.
