Now, I can see why G would be slow to move on click fraud. After all, it makes them money, and if you can't monitor your own logs to the point where you can't recognize it, then it's your own fault (I don't actually believe that but it's what I've resigned myself to thinking) but what about impression fraud?
Over the last few days I've been noticing terms (or certain variations of said terms) with unusually high impression counts. Seeing as my terms are geocentric I've been noticing the same variation of a term along multiple regions with this unusual activity whereas this particular term never had such high numbers before. For the sake of simplicity I'll do a fake example:
Terms would be...
This Widget Texas That Widget Texas These Widgets Texas Those Widgets Texas
Normally "This Widget Texas" would be the highest searched term. A run through Wordtracker would confirm this. Now "These Widgets Texas" has 8 times the impressions with the same number of clicks it would usually get. And it's the same situation with "These Widgets Florida" and "These Widgets California"...you get the idea. It reduces the CTR and drives up CPC.
Has anyone been affected the same way lately? I'm guessing it's pretty rampant in competitive markets.
