If you work with Google Analytics, eventually, you’ll probably be faced with a situation where you are unsure about what data is being sent by ga.js to Google’s servers. Google recommends several different ways to troubleshoot the GA tracking code. However, if you are just trying to find out what data is being sent to Google, I recommend using the Google Analytics Tracking Code Debugger extension for the Chrome browser. This works especially well when looking at custom variables, or when you are trying to ascertain whether or not an event is firing.
