I suppose google has a mass of data about what people appear to be searching for.
Then if they tweak their program (quite a lot) they may be able to infer whether the searchers found content that satisfied their curiosity or not, possibly something they would infer from the searchers behaviour.
Then they have what people are seeking and where that is or is not being provided. But what do they do with that information? To whom is it valuable? and why would such a reasonable process be patentable?
