Any remedies besides eliminating the Content Search option for the PPC program?
jkc1,
Well if you believe that the Content Network can be made profitable otherwise, then sacrifice that one Turkish visit a year (sorry, potential customer!) and take Turkey out of your country list in your campaign Location list for starters.
Sadly, it's often not practical to let the entire world in on your list in the location list under campaign settings. "All countries" is the default.
You can also block the domain they come in through the AdWords UI. Still, click frauders have a huge array of tools available now to stymie some of the obvious defences we have. I'm sure others can suggest a few more options to keep them away from your ads.
It sounds like some "Made for AdSense" network of sites there has your ads showing since I advertise in Turkey too and never noticed an inordinate amount of traffic from there. A few other countries I have to bypass though....
Unforunately, because of the PPC model, click fraud represents a sizable amount of PPC income and if they were to be truly pro-active in preventing it, they may find a house of cards collapsing around them from a revenue standpoint.
I'm a little tired of the response that I often see that click fraud is simply a cost of doing business, like shoplifting. Where are the police though?
