Event tracking is very useful to track things like how many clicks to external sites, opened PDFs. For video sites you can track how many people watched 1 min or 10 mins of a video, or event how many people mouse over your logo etc. To use, assuming you installed the newest Google Analytics asynchronous tracking code. And assuming you want to track how many people clicked on a link that leads to an external site. You can use it like: <a href="some_external_url" onClick="_gaq.push(['_trackEvent', 'Link', 'External', 'some_external_url']);">Go to the external site</a> Code (markup): Full document can be found at: http://code.google.com/apis/analytics/docs/tracking/eventTrackerGuide.html Or you can reply on this post if you need further instructions
