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.
I'd assume that someone would have to have an O.K. CTR and bid, then pause for a while (maybe a week) whilst the attack runs for maybe 4 days during their pause.
It's scary when you think how it effect people.
