I just stumbled across a keyword that apparently has a $7 CPC. All related keyword have a $5 - $10 CPC as well. However, when I search for the keyword and look for websites in the top 10 showing Adsense, none of them appear to have niche specific ads on them. All of them are for the Adwords default ad that Google sometimes puts up. The niche doesn't seem very lucrative either. There aren't even any paid ads when I search for the keyword in Google... How is it possible for the keyword tool to say $5 - $10 CPC with no apparent ads for that niche? Could it be a mistake on the keyword tool? Anyone have experience with another scenario like this?
