Analytics: The discovery and communication of meaningful patterns in data.
Google Analytics is a funny thing. On one hand, it’s a powerful (free!) tool that offers you seemingly limitless data about your blog. On the other hand, it has the potential to be a huge distraction and an emotional roller coaster, as your mood directly reflects the ups and downs of your blog’s traffic.
If you’re new to blogging I recommend that one of the first things you do is install Google Analytics so it can start collecting data right away. After that, however, I’d do whatever you can to check it as little as possible for the first year of blogging.
