I am looking for input about the keyword analysis tools. As much input as possible would be great to get a good resource for people looking to do keyword analysis. Please include if, free, and why you think it is good. I will start the list: GoodKeywords - FREE www.goodkeywords.com It is free, and pulls some interesting data. WEBCEO - PAID It give a nice report, and pretty accurate data, Wordtracker - Both FREE and PAID Definitely give some good keyword analysis SEOBook Keyword Research Tool Free on SEOBook.com I know I missed tons of them, so please add your favorites to the list.
We're also using those you listed, tried wordze but we're sticking with the free tools for now. The tool from seobook is pretty good.
7 Day WordTracker Free Trial ...Will give you KEI based on your Industry from Top Search Engines over a period of 90 days. Wordtracker periodically compiles a database of over 330 million search terms which is updated on a weekly basis. All search terms are collected from the major metacrawlers - Dogpile and Metacrawler. Click on the first link in my signature.
For both competitive and volume analysis - Wordze is what you need. Dont use KEI as a metric, it doesn't make mathmatical sense on a large scale. Also try SEOmoz Keyword Difficulty tool.. They created their own little KEI (Sort of) but it is really handy. It is a paid tool.
Keyword Discovery is also quite good. As far as free tools go, the SEO Book research tool is pretty handy
