There is one thing I hear a lot when I’m giving talks about Google Analytics: “I didn’t know Google Analytics could track that!”. Put another way, I just as often get a question like “Could you make Google Analytics track [insert anything here]?”. The short answer is always, “Yes, you can track that in Google Analytics”. Basically, you can track anything that goes on inside a browser. If it happens within a browser (a mouse click, a keyboard key click, a mouse movement, scrolling) you can track it. This means that we can make Analytics listen for and track anything that happens in the browser as long as it’s triggered by the user. Luckily, there’s a nifty thing called event listeners help us.
