Sample Question
In many ways, SmarterStats analytics are more accurate than Google Analytics in terms of tracking bandwidth because

Google Analytics can only monitor store front traffic, not admin traffic (including bandwidth generated by use of the API)

Google Analytics is controlled by JavaScript. This means that if the script fails to load, or if the page doesn’t load all the way, the bandwidth will not be recorded in GA.

There are a large number of extensions for Firefox and Chrome that are designed specifically to not respond to the Google Analytics script. In other words, they allow you to “opt out”

All of the above
