In my country there are too little search volume to get displayed in the biggest of this services. Google KW Tool is good, but I loose a bit of the "juice" because important keywords may not be searched for more than 200-300 times a year.. For clients dealing with $million USD it is important to be visible also on low search words and phrases and this is problematic..
Thanks for the nichebot suggestion above. How about KeywordCountry.com? Anyone use it and find it useful? I'm looking at: Adwords Dominator but working up the money to get it. They also have a keyword database recently launched. How do the free ones match up to the paid ones? Any difference?
I use both google KW and wordtracker, and find googles KW tool to be more 'accurate' with traffic numbers.
