Were you using AdLogger? Most probably you've learned about its MIA development now. Too bad since it's one of the best AdSense tracking tools that doesn't cost a thing.
Since we're into anything free, I'm quite sad to say that Asrep - this other ad tracking tool that I've just known about recently costs $50. Yes, its full-version does not come for free.
However, a yay for us freebie-lovers since its trial version which can be used infinitely or just as long as its makers keep it that way, is free!
So what are AdSense publishers allowed to do with the free version?
* Click fraud detection and prevention tools.
* Domain, page, directory and and sub-directories reports.
* Channel reports.
* Referrer domain, page, and search term reports.
* Visitor IP and Country.
* Reports of Ad Unit Colors and Formats.
* Search box search term reports.
