I use both Wordtracker and keyword discovery but I prefer Wordtracker and it’s the leader of the industry anyway.

One thing to consider; before using your keyword research tool it’s better to expand your keyword list and there is a little free tool that does just that. It’s called the keyword research engine.

It helps building a much better keyword list for any given market.

Hope this helps…

As with WordTracker you can also try the KeywordDiscovery – Keyword Research Tool which has a much larger keyword database. Great for tail end and niche keyword research.
