Have a whitepaper or some other file available for download on your site? With event tracking in Google Analytics you can track the number of times a particular file has been downloaded. Use the form to build GA Event tracking code for file downloads, then add the code to the file download link to track the event.
After you add the file download event tracking code to your site, you may want to setup a goal in Google Analytics that's related to the event. Follow these instructions to setup the goal.
