I found this thread http://forums.digitalpoint.com/showthread.php?t=82173&highlight=which+ads+where+clicked I'll give that a try guess I should have used the search feature
I use addfreestats.com Not perfect maybe, but you can combine it with your chanels tracking and your hosting webstats. And it's free
asrep is free and offers great stats. Since website logs show search engine spiders as well, asrep is also a great way to determine which pages are actually viewed by humans. It usually tied with the stats reported by AdSense.
AWSTATS is also free and it monitors both viewed traffic (human) and non-viewed traffic (bots and spiders). And it looks nice
I would recommend Awstats they show everything in detail if you have cPanel you can see the stats via awstast in cPanel. Thanks,
Have just started using http://www.adlogger.org It may not be perfect, but it is definitely the easiest to install and produces very nice, clean stats that show almost all that is possible about the visitors who click an Adsense ad. P.S. can Awstats be used to track Adsense clicks? Never seen that before and I use it daily, think they only display regular stats and that is of no use if you want to know about who/what/where/how Adsense clicks are produced.
