Which free keyword research tool to use?
Posted by Kev on Saturday, February 03, 2007
This has been an important week for free keyword research tools, Overture's tool has been unavailable for the last few days (now back online) while Wordtracker and KeywordDiscovery have both released free versions of their own keyword research tools. So now there seems to be much more choice to find the best keywords, but which tool is best to use?Overture

I've been using the Overture keyword tool for over a year and while the responsiveness has sometimes been very slow I have generally been quite pleased with the results. The search count has been lower than I expected as these figures ar e only based upon Yahoo! queries from the previous month and occasionally some strange long-tail results appear, such as the "beer college college..." result above but overall this gives a good idea about the popularity of keywords. Another advantage I like is how you can search to find the popular keywords in the UK using the Overture UK tool.
Wordtracker
KeywordDiscovery
I've only briefly used Trellian's KeywordDiscovery tool but I have been very impressed with the results returned. The accuracy of search figures looks to be much greater than both the Overture and Wordtracker keyword tools, mainly because search data is collected from all major search engines.
Overall I find KeywordDiscovery to provide the most accurate results and search terms but would also suggest comparing results over a couple of keyword tools to make sure your not missing out on some valuable long-tail keywords. Personally I would probably compare the KeywordDiscovery results with the Overture UK list to check that the British have the same search trends.
Google Trends or the AdWords keyword tool could also be useful options, but I'd prefer to use tools which combine keyword suggestions with search stats (although the AdWords does display a search volume indicator) so I normally wouldn't use these as regularly. What does everyone else think, which keyword tools do you prefer to use?
