I need to identify my users when an ad is clicked. For example, when user A is online, I need to know that he was the one who clicked the ad unit.
When using my own ads, this was a piece of cake (using URL redirection) - however, now we are planning to switch to Adsense - which renders the Ad via javascript - hence I cannot setup a redirection there.
How do I track - which user which ad unit - in case of adsense?
Thanks alot.
