Willingness to hand over credit cards and receive prescriptions relate to ecommerce...but ecommerice is a small percentage of the web! Most websites don't directly sell things.
That's an interesting idea. The very act of including these criteria may have created an e-commerce friendly algorithm.
To take it further, if you got raters to say if a site "feels like it was written by a real person" you might get a blog-friendly algorithm; if raters are asked to say "The motives of this site are pure" you'd get a bias towards non-profits and away from e-commerce.
