Am getting tired of this Google keyword tool. Or is it me doing something wrong? I intend to use it to optimise adsense on my blog. But i am getting confused now. Ok, i used the tool to look for a keyword. I got $0.05 on as the estimated avg cpc but when i checked with Google's traffic estimator, it was a different ball game entirely (giving me $0.57). I noticed this big difference. The value for the estimator is always higher than that of the tool. Is google trying to confuse somebody here?
