1) It is simple to install. It literally took me less than one minute to download from codeis.com and install on my website.
2) It works! The only thing you have to do is enter your unique web id (provided by Google Analytics) and you're DONE! It works straight out of the box assuming that you have set up your website tracking profile in Google Analytics correctly.
This is an excellent addition for any Joomla based website. Highly recommended!!!
