Click fraud detection software?

Looked at several PPC services but not convinced by any of them, does anyone have any recommendation?

I’m looking for either an offline tool or online service which does more than simply look for multiple clicks from the same IP.

Thanks

You probably want to use Asrep to monitor your Adsense, this way you'll be able to determine if it's the same computer systems clicking the ads. This way, you'll know about it and be able to report it to Google, before Google reports it to you, if you know what I mean.

Asrep does all types of Adsense tracking, and it's useful for finding out what ads visitor's click, what pages they do the clicks on, the clickers ip, geo-ip data, a whole ton of features. Thats definately a tool every Adsense publisher should have in their back pocket.

Thanks but I’m more concerned with the thousands I spend on AdWords each month and the occasional freaky days where CTR goes through the roof – manually sifting through logs isn’t an option and i don’t have time to write my own solution.

PuReWebDev...I have been told by my google & overture team that they have fraud protection already built in! Is that true?

they do have built in fraud protection but I personally don't think it captures nearly everything and that you still need to exercise a good degree of personal review. I recieve quite frequent credits from google for click quality adjustments which shows they do capture some stuff, however there have been numerous occasions where I have had to submit reports to them regarding suspicious activity that hasn't been picked up and subsequently led to credits back.

My best advice is get to know your traffic, experience with an account and being really anal about every little detail and variation soon leads to spotting questionable traffic second nature to spot

I am actually also currently looking into third party solutions to try and make sure I capture as much dodgy goings on as possible, so if anyone has any reccomendations they would be much appreciated
