Tracking website traffic is easy with Google Analytics.
Simply grab your tracking code from Google Analytics and add it to your site by clicking Manage Site > Meta / SEO then insert your code into the Google Analytics field and save.
With that update, website traffic information will be sent to Google Analytics for tracking.
