Keywords related to an IT website !

Hello friends
I am working on my IT website which offers Database tutorials, source codes, IT news and Software downloads. URL is www.webjoogler.com
I am facing problem in choosing keywords for my google ads for this website only, I tried using some keywords related to Computer sciences, but i am not paid more than 0.75 $ on 2 to 3 clicks.
Please suggest me some good keywords which i can use to earn more..
Thanks in advance

 

I really like yourwebsite but if i could give you a small suggestion replace links with textual ads

 

Thank you so much for liking the website, What impact would my website have, if change my image ads to text ads ?

 

The top keywords are data and data recovery etc.

 

Thanks ! Do you know any other keywords?

 

You can try MarketSamurai and tools.seobook.com.
This 2 is what im using and is very user friendly and powerful.

 

Are these the keywords?

 

No, it is not.
I mean you can try this software application where its able to help you do keyword research, which keywords are more searchers, which has more CPC and etc..
