GA is probably not real time but Woopra is. I trust GA more because they have a more legitimate system than anyone else in the market.
The fundamental offering purpose of Woopra over Google Analytics is that you can see the guests on your site progressively. You can likewise backtrack and track the way of an individual guest.
With the help of Whoopra you can see who is on your website, where they are located, how they found you, and what path they are finding through your website. Google Analytics is more about collecting that data, sampling it over time, and storing it so you can hammer it into whatever dataset floats your boat!
Woopra is a hit counter and analytics software another such tool I use is gostats .. GA is a popular analytics software as most of the blogs sites use it ... con it uses sampled data ...
