You don’t need to do anything if you just want Google Analytics to measure your traffic in Virtuemart. However, if you want to set a goal to track sales conversions, you need to provide Google Analytics with a unique URL for the result page in Virtuemart. Follow the below steps to do this:

1. Creating a normal html page called analytics-result.htm
2. In the body of this page you put your analytics code. Make sure you are using the Analytics code for secure sites rather than the standard code if your shopping basket is secure.
3. Save this in a location accessible through https (if you are using a secure checkout). For example: https://www.yourdomain.com/analytics-result.htm
4. Search for: /administrator/components/Virtuemart/html/checkout.thankyou.php (if encrypted, request non-encrypted version from us)
5. At the end of the php file, add this code:

   <iframe src="/analytics-result.htm" width="5" height="5" frameborder="0" 
   scrolling="no" name="Analytics"></iframe>

    
6. Setup a goal in Analytics and give it your new page as the unique URL: http://www.yourdomain.com/analytics-result.htm

What this method does is to put an iframe into the thank you page after a customer has ordered. This iframe contains a standard HTML file with a unique URL that you can set up as a goal page in Analytics. As long as everything is done through SSL your customer should not get any security errors. Only use https and SSL if you have already set this up on your domain, otherwise use http.
