There’s an interesting thread over at HighRankings Forums on Wordtracker and Keyword Discovery debating the accuracy, pros and cons of each. I’ve been a Wordtracker user for at least 6 years and have been dabbling with Keyword Discovery off and on for 2 or 3 years. Both have their pluses and shortcomings.
I am curious if readers of this blog can help me out and provide any insight into your use of Wordtracker and Keyword Discovery for keyword research and analysis? Likes, Dislikes? If I were to switch to just one service, which would you recommend?
