There's definitely got to be a market for a company with better data on the value of a given site to advertisers, you just have to figure out how to get the data. What about some sort of third party google analytics that specifically targeted whatever metrics make advertising more profitable? If you could prove your metrics were worthwhile maybe you could convince sites to embed your stuff to get a good rating and you could sell ratings to whomever is selling or buying the ads. There's sort of a cart before the horse problem there. Ideas?
