Like most people, I get fed up with search results that assume I'm automatically looking for something to buy. I'd love to be able to run a search that only turned up pages without any advertising or sales orientation.

Does Google have a switch/option to do this? If not, bearing in mind that it would effectively ban pages that carried Google ads too, would they ever be likely to do so? (They could still have their advertising on the search results page)

Is this pie in the sky? I'd imagine that the quality of results for such searches would dramatically improve.

I should add, I wouldn't be looking to strip advertising out of a page. I'd be looking for websites whose raison d'etre isn't the immediate selling of a product. For example, I might be looking for the history of a company, rather than to buy the product it sells.
