Is there any problem with my ad layout or content? Why CTP is so low.

I have try my best to improve the article quality, not simply copy from other site. I paraphrase them or combine sources together. Will that still be regarded duplicate content by Google? And I have tried to submit to social bookmarks.
Also, is there any problem with my AD layout? Why clicks so few....

My site is http://www.48da.com/ It's a blog based IT news site.

 

Its all About the Fake traffic and Invalid visitors ..Every ones facing this kind of problem from last 2-3 Weeks ..

Only the Solutions is do Effort on New Content and New Info wish sincere Dont create fake traffic for your web its bad for Adsense

 

I have to close some AD, the keep decreasing CTP is affecting my click price.

 

Any other opinion?

 

do you pay attention to the keywords when you rewrite? It does not matter whether clicks are few or many, what is important is the earning per click.
No point getting many one-cent clicks, best to get a few dollars per click.

 

Thanks I will improve on that
