But don´t forget to have a closer look on your opponents? Let´s say you start a online store, you sell computers. Further, let´s say you find your keywords like harddisc, cd-rom and computer. You can see that those three keywords generates ten millions search in a month. That´s great, but I guess you have some opponents with same products like you, maybe you even better. It does´nt really matters, your site has pagerank 1, microsoft, fujitsu- siemens, ibm etc. will still have a pagerank between 7-9. Even sites who not sell a product have better pagerank than you.

I think this tool is great, but as a guidance-tool to avoid keywords who does´nt help your site from day one. Of course you have to mention same keywords as your opponents, but with a tool like this you can try to change keywords with grammar and maybe a spelling mistake?
