Today my cpc has doubled. This is annoying because you can be almost certain that eBay's ad isnt going anywhere anytime soon. I've seen it on many other keywords and eBay never budges.
The only reason I say "google uses" is because it's very unlikely that these companies work on their own to include so many irrelevant keywords. I imagine Amazon, eBay etc work with Google to some degree.
Anyone else notice these things?
Did you know that you used to be able to bid on Matthew Broderick on eBay? You can't bid on a viral infection, but manymany searches pop an eBay result.
Why wouldn't they? Sometimes it's pretty funny ..
P.S. They use the current variant of
{KEYWORD} to get the ad-writing job done.
