Joomla analytic plugin ?

I have a very large joomla e-comm site that I need to keep track of. Can anyone recommend
a good plugin to use ? Sorry if im in the wrong section

I have been using for example this one, which is rather good:

http://extensions.joomla.org/extensions/site-management/analytics/site-analytics-google-based/6170

It automatically inserts the code to the HTML-pages.

Since you mention you have an e-commerce site, you probably need to track also the conversions?

If you pm me your URL, I can also take a look.
