I wonder about the "quality" of those searches on each of the search engnes. Ask, for example, is going to target younger women. If successful, that would be high quality for many marketers.

Not to pick on Yahoo, but in my experience their users are more down market. Now, that is not a bad thing, depending on what you are trying to market.

But, in real estate, educational services, autos and news--the three categories I have a tad of insight into--G leads the way even more than these numbers suggest. From what I see (and it's just a tiny sample) G is closer to 75 percent in those areas.
