I dunno why this is the first time I ever saw this, but this tool essentially enables automated long-tail exploration and discovery. And while a similar valuable tool is available via SEOmoz Pro, this one is free (for now) via Yahoo. (Though obviously, SEOmoz has a lot of other tools Yahoo does not.)

I’m talking about Yahoo’s Term Extraction Tool. You give it a page, it tells you the relevant terms found there.

For example:

“Italian sculptors and painters of the renaissance favored the Virgin Mary for inspiration.”

italian sculptors
virgin mary
painters
renaissance
inspiration

Use something like that on a Wikipedia page and you’re getting into the money…
