SEO Book Keyword Research Tool
I don’t know if I’ve been asleep or what, but I hadn’t noticed that the SEO Book website offered a version of their keyword research tool using Wordtrackers’ results. Back about a year or so ago (before Yahoo stopped Overtures updates) I would use the older tool as a semi-valuable research when considering the popularity of a search term… but once Overture stopped updating, I found the tool less & less valuable.
