You could put our version of the GA code in your page HEAD, but that could adversely affect your page load performance, so we recommend putting it at the end of the BODY, where it won't hold up loading the rest of your page until after the script has loaded. Google's newest GA code is asynchronous, meaning it doesn't hold up page loading while the script loads, so it can be placed in the HEAD without affecting page load performance. We intend to update our GA code to take advantage of Google's new async method eventually, but right now we've got our hands pretty full with completing the new Admin project and upgrading our 2CO support in response to the imminent retirement of Google Checkout.
