They're not passing the "best refrigerator" test yet: http://blekko.com/ws/best+refrigerator

Did you try adding /reviews ? Sometimes we can deliver better results without the user doing anything different from what they're used to doing, but not always.

can anyone explain what bayes and mfa mean? I picked the site http://www.basemetals.com/ (bayes (spam 8.6 > 5.3)) at random, and although it won't win any design awards I can't see what the problem with it is. Am I missing something?

I guess Bayes refers to running a Bayes-based classifier[1] on a certain site in order to infer the probability that it is a "bad"/spam one.

On the other hand, I have no idea what mfa means.

Two big problems with automated spam blocking are: false positives and changing domain names.

For the second one, how often do you revise your blocked links? what if it changed owner and the new one doesn't provide spam.

For the first one, is even one false positive tolerable? Will you deny someone presence in your index because you failed? And if so, how do you handle challenges?

mfa = Made for Adsense. That means we believe that the domain seems designed more to show ads than to provide content.

bayes = our Baysian analysis gizmo thinks bad things about this site's content. Too much Viagra, not enough content. Like all artificially-intelligent things, it can sometimes be hard to see why it's upset.
