Installing google analytics, is not only easy and straight forward, but it’s absolutely essential to making sure all your blogging efforts are getting to the people you want.
Once you’ve clicked the install button, WordPress takes care of the rest. All you’ll need to do once it’s installed, is click the activate button and supply it with the necessary credentials. My suggestion is that you authenticate with your google account so that tracking your stats can be done both inside the dashboard and in the google interface.
Having this information can tell you many things about how folks are viewing your blog. Digging deeper it can be a great tool for figuring out what content readers seek the most.
