How do you find the top paying keywords.

Hey all I have been working on www . redneckrealitycheck . com for about 3 months now. I keep reading about finding the top paying keywords. Where do you go to find whats the highest paying for adsense. I am lost on that aspect. All I have been doing is researching key searches using the seo toolbook.

I dont know if this is a secret thing but any help or advice would be greatful.

Thanks in advance

 

i think keywordcountry is best for you

I appreciate both your replies, I will be checking both of these out.

 

I have bum marketing software which gives me an estamiate on the number of searches and stuff

Try to mix adwords with http://www.google.com/trends/ to find a high traffic + high paying keyword

 

this keyword country site appears to have it all, anyone else use it with any success?
