Because links that lead away from your site are not automatically tracked by Google Analytics, you will need to manually tag all outbound links you want to track. To do this, you will add some custom JavaScript that uses the _trackEvent method to record these links and then modify the links you want to track. These instructions assume you already have either the traditional (ga.js) or the asynchronous tracking code in your pages, that you have some familiarity with JavaScript, and that you can edit your website pages to include this JavaScript.
