IWebTool.com just released a membership based keyword tool that is pretty neat called Keyword Lookup. The registration is free and the tool is pretty cool. It allows you to see all the top searched for words in order. You can not only keep going down the list until you find the least searched for words but you can have it display up to 500 words/page. It also allows you to search for a specific keywords and find the related. Pretty neat tool I thought.
