Hi, I know there are lots of types of keyword software out there, like Keyword Country, Keyword Elite, Adwords Analyzer and so on. But, is there any software that is free that will provide lots of long tail keywords and maybe the competition or searches ? Mainly for Affiliate marketing or Adsense sites. If not, what is the best paid software for this ? I just bought Adwords Analyzer to avoid paying monthly fees all the time, but I'm not sure now if it is as good as Keyword Country, for example. Thank you.
