I am here to recommend you a good keywords optimization tool which can help you earn money on line easily! http://www.keywordsmaster.com
Are you sure that's a keyword tool or are you trying to promote your website. I feel its not a keyword tool at all
Finding valuable keywords can't be taught. Of course you can always take a guess at the beginning of a campaign but you only find the REAL ones by driving traffic to the specific offer/product you're promoting and THEN finding the winning keywords that are obviously making you a profit and cutting the ones that are losing you money. That's all done by always tracking everything. Every keyword, URL, headline, etc.
I just think Google and SEOBOOK are the best tools to find valable tools keywords. I always use them.
