Since your Google Analytics tracking code doesn?t exist on 3rd party websites you link to, Google Analytics won?t track this (at least not in your account?the site you link to may also have GA, but for privacy reasons, Google won?t share their data with you). Likewise, you can?t embed your GA tracking on a PDF or WMV file.
Fortunately Google Analytics supports the JavaScript pageTracker function. Inserting this function into the events you want to track (links or file downloads) you can send this information to Google Analytics to track as a pageview.
