I’ve just started contributing a bit to the Wikipedia article on Web Analytics. My main focus right now: The difference between web analytics and web traffic reporting.
Analytics is the practice of analysis, where a person looks at data and attempts to draw useful conclusions.
Traffic reporting is usually done by software, like Google Analytics (a confusing name) or Omniture.
I’ve talked about this before, but I think it’s becoming my latest internet crusade. Free the analyzers! Give them credit where credit is due!
