Rather than trying to make this post go through all the tactics and specifics of Rebecca's already comprehensive Keyword Research Guide, I figured I'd instead provide a solid list of every which way you can look at a keyword to get an idea of metrics, value and potential from the engines themselves (rather than services like AdWords, YSM, Wortracker or KW Discovery). This is more of an "expert" level post, as you'll need to use these searches/tools yourself to figure out exactly how they apply to your business, but it's stil valuable to have all of this collected in one place.
