I have a question that I'm hoping someone has an answer to. Does anyone have any suggestion for some software (preferably free as I'm on a tight budget) to do keyword analysis? By "analysis" I'm talking about determining whether or not a keyword is good to go after. Something like what Micro Niche Finder does with its red/yellow/green rating. I know that Market Samurai is capable of doing keyword analysis in a similar but more in-depth manner and is free but I can't get it to work--every time I try it, it times out.
I don't really need any other features, just something to speed up the keyword choosing process. At the moment I'm using Google's Keyword Tool to find search volumes for keywords and then checking promising looking ones in the main Google results to see the PR and backlinks and so forth for the sites that show up for those keywords and, while no doubt effective, it's quite time consuming. Something that I can just pop a list of keywords into, hit a button and get an "easy/medium/difficult" rating for the keywords would be nice. So, any suggestions on a way to automate this process? Any software or websites that do this or am I stuck manually using Google?
