TRACKING PIXEL:
Place this 1x1 tracking pixel image on the page along with the creative:
Use this link as the click-through URL:
href="http://n4403ad.doubleclick.net/jump/gn.chud.com/redirect;adid=210075691;sect=redirect;sz=1x1;ord=[timestamp]"
IMPORTANT NOTE - BOTH of these must be on the page for the click-through to work properly. You cannot just use the click URL alone. Also, the 'ord=[timestamp]' must BE THE SAME on both the image and click URL for it to work properly. You can either dynamically change the [timestamp] variable using Javascript, or just hard code the same number on both like this:
ord=1234567890
