Thanks Isobel...

Leigh, I was checking out Waypath, and they have a pretty cool tool called the "Buzzmaker".

It lets you enter 5 keywords and it will create a graph of the popularity of each keyword/phrase.

While the "Buzz" isn't search engine content, but it does add some interesting content for your visitors and could "fill up space" when you need something, anything, when trying to make a page.
