Summary
Rapid Keyword is a very handy keyword tool. It has almost every feature you want in a keyword tool. The keyword research function allows you to enter a keyword or a keyword list into the tool and then Rapid Keyword searches every keyword in that list to find more related keywords. The benefit is that you can insert an entire keyword list into this tool rather than just one keyword at a time.
Rapid Keyword will analyze your keyword lists, which tells you how many webpages exist for that keyword, the number of searches, and the number of pay per click advertisements for Google, Yahoo, MSN, and Miva.
The other features that come with Rapid Keyword are a very nice bonus. The ones we particularly liked were the remove duplicate keywords, remove a list of keywords from another keyword list, and remove any keyword from a list that contains a certain word or phrase.
