Soooo low CPC, how should I do to improve

[cuongdm]

Hi guys,
this is the issue
----------------
URL: http://www.thefamous.info
Description: this site is about The Famous People Information (such as: Paris Hilton, Britney Spear, Lindsay Lohan... )
Ads Position: I put some referrals on the left, one large vertical ads on the right, and 2 small horizental ads on the main body
Problem: the CPC is too low, when people visit a page, the adsense will show the relevant ads of this people (for ex: Paris Hilton free pics, Paris Hilton video... ) i know it will make the CTR higher but the CPC is toooo low...
----------------
What I want: The content is still about the famous people but the ads with higher payout keywords... should I change the Page Title, Keyword (now is following the content)... or put some more content target to the new keyword...
---------------
I need your suggestions...

I guess, Adsense and YPN are almost the same with regards to keyword bidding
