Any idea as to what I can do to prevent a huge influx of click fraud from sites hosting Overture/Yahoo content managed ads? The last few days, my traffic has gone through the roof, but it's all been from visitors who are primarily in Turkey and throughout the middle east. There are others from around the world, but that region seems to be hitting me the hardest. I haven't had this problem with Overture in the past, at least not this blatantly. Is there any recourse in these cases, or do I just cancel those key words and move on? The traffic spends just a few seconds on my site and only lands on the home page and then leaves. Just curious if anyone else has been noticing this same phenomenon over the last couple days with their Overture ads.
