Adsense Keyword Analysis Tool for Blogs? Any idea?

Hi, I am wondering if there is any popular tool for wordpress blogs to know which keyword has given me maximum earning? I frequently get random clicks of high earning but I am not sure which keyword(s) is bringing those earning as I mostly have general blogs.

Please advise. Paid or Unpaid script is okay.

Thanks,
bnts
