Can anyone help me work out the best way of tracking down niche keywords for Organic search. I am performing keyword analysis for an eye laser surgery company. I have access to and experience with wordtracker, but it's keyword universe tool (with competition search) is only suggesting absurd keywords/keyword phrases with KEI greater than 10 for any seed keywords I enter. I'm entering all the eye treatment names and much more supplied by the customer. My questions are a) whether I'm better off with nichebot which somehow differs radically from wordtracker in its suggestions - it has made some sensible suggestions (but are these trustworthy?) b) Are the 'keywords to consider' which the Google adwords tool delivers OK to rely on for organic search? What I am doing here is looking for search volumes which are average and above and where the competition is average and below c) Are there any other tools I could use? I am not using overture because I am trying to find niche keywords not ones necessarily with high search volumes.
Any help would be greatly appreciated as I have spent all day at this and need to come up with 8 reliable niche keywords/keyphrases.
Does the client have a search box on their site? If so could you get access to that to see what visitors are searching for while on the site. That could provide you with some interesting keywords that you or the engines may not have come up with.
