Just a thought: don't those 75% reflect rather badly on Google's search skills? Those 75% translate into 75% false hits delivered by Google - room to improve for competitors.

Although granted, there might be a barrier of human "stupidity" that can't be broken, there is only so much you can infer from simplistic search requests.

Oh good, I don't feel quite as bad about my ridiculous Google Analytics charts:

From your site: "It's still being put together so there's lots of content missing" and "This text is filler. Lorem ipsum..."

Wonder why your bounce rates are high?

I suppose it's pretty neglected. I've been "putting it together" for the last couple years :)
