well the best one I found is Adlogger (just add a dot com to that to get the website) I am not sure if it works with Firefox too but the stats are usually fairely close with Google resutls.
It can also alert u when a same ip clicks on more than one Ad

Interesting. I saw a big hit on one of my sites, the Link Unit ad on that site. It just launched recently, so it's barely getting any traffic - but for 11 page views, I had 13 clicks -- all on the Link Units. Do you track your ads via channels based on ad type ... and if so, do you know if it was link units that were being so heavily clicked?

Thanks Guys!

I will try one or the other - whichever is easier...

I am not currently tracking ad units - just pages...

Every one of my pages has 1 set of ad units and 2 ad boxes (which vary a bit from page to page)...

So... I am pretty much working in the dark - but the above recomendations will surely help.

If a new ad appeared on your site that interested your visitors significantly more than the ads that HAD been there, you could see this.

Any new ads?

Well... That is a thought.... but I have an information site... everyone that visits comes only once....therefore any new ads - no one would notice.

I did optimize my format though and I am sure that has soemthing to do with it...

I added an embedded ad block of 225
I added another small skyscraper to the right....
I moved a large leaderboard from the top to the bottom...

Tinkering is all I did.... who knows...Maybe I finally got it right?

i got a 700% increase one day, thanks to playing around with new ad formats. Perhaps you did things well :)

leolapinos...

I hope you're right.... if tinkering made the difference... then I can move on to producing some more content...
