Is there a way to find out if my competitors have initiated some kind of a click fraud campaign against me?
How would click fraud result in a CPC increase? If anything, an undetected increase in CTR (if competitors were fraudulently clicking your ads and bypassing Google's filters) would play a role in a higher Quality Score, and thus lower CPCs as a result...
Higher CPCs, to me, is more likely legitimately driven by higher bids, increased competition, or poorer Quality Score.
