There are always methodology questions with data like this, but I've looked at the AOL data and am comfortable assuming that the categories are at least approximately realistic.
It's interesting to see the smooth spread across so many different categories. It's also easy to see why only focusing on a category or two may not be an effective product strategy. Shopping is the most lucrative of the verticals, and a healthy chunk at 10% of all searches. But if you focus only on shopping, that means users have to go elsewhere for the other 90% of their searches.
