Yes, precisely. What matters is the audience demographic which is attracted to the page and visits the page in the largest numbers. I'll freely admit that I'm making educated (as opposed to idle) speculation here, but, I'll reiterate, I suspect it is quality traffic that counts here, not quality content.
That is not to say that quality content is an irrelevancy. I don't think you'll get very far in the organic SERPS for instance if you don't research and write original and useful information. But I don't think quality content per se has much bearing on smart pricing.
Nor me if we were talking about pre-IPO Google with its mission to re-academise the web. But we're not, we're talking about post-IPO Google and while I think that Google still maintains that ideal to some degree, I also think that - more often than not - it plays second fiddle to other real-world concerns like providing returns for its shareholders, so it can keep raising equity to fight off the behemoth from Redmond and other contenders.
