Traffic Travis lets you organize key phrases into groups based on one specific keyword. There are a ton of filtering options (for
example, you can find partial or inverted duplicate phrases), and it costs about $100.
Web CEO organizes keywords into baskets using whichever criteria you choose. Smarty says that the tool gives users "unlimited freedom." "You can sort your keywords based on search volume or competition, term topic (e.g. general; location-targeted; brand-related searches; etc), query type (navigational vs informational), keyword potential (commercial vs informational) or any other you can think of," she notes.
