As for URX, a company whose pitch is "Get paid to link into apps. It's not an ad, it's an action" probably isn't interested in improving search quality.
There's a big opportunity for Apple to move into search and offer a higher-quality experience for Apple customers. Apple makes their money selling to their users, not selling ads.
(Our pitch, of course, is to automatically do some due diligence on the company and use business legitimacy as an input to ranking. This works reasonably well, but for an ad-supported search engine, does not maximized profits. Adsense (ads on third party sites) is 30% of Google's revenue.)
