Few days ago I went for a discussion on keywords with my client, I mentioned that I'm currently using the Google keyword tools and he said that Wordtracker is the most superior tool and that is what they use for their keyword research. However, when I mentioned that I had used Wordtracker in the past and I didn't find it all that good he stated that it takes a lot of experience to know how to use Wordtracker effectively. Is Wordtracker a superior tool than Google Keyword?
