What is the rate per click? Google has kept it a secret. It is also against the adsense policy to disclose your CTR and income. We can assume that the rate depends on the content or niche of the site and competition in that niche. For example high competition keywords include financial products like credit card, Loan, Personal loan. These are also high paying too.
