Two Free Keyword Tools from WordStream
Two new keyword tools were released by keyword research firm WordStream, a free keyword niche finder and a free keyword grouper.
The Keyword Niche Finder enables users to enter a keyword to fin valuable pockets of keyword opportunities, returning structured keyword suggestions for use in search marketing campaigns.
The second tool released by WordStream is the Keyword Grouper, which lets users enter a list of keywords or analytic data and get back related groupings to use in PPC ads or even Web copy.
Both look like pretty basic, but are another set of free solutions for your SEO and PPC tool chest.
