Cutts: "It sounds like Hitwise's definition is "A successful search is defined as one where the consumer leaves the search engine after performing a search." In another words, the user does a query and then goes somewhere else. That doesn't sound the same as success to me; it just sounds like leaving the site.
One has to speculate on whether or not he would have been happy with the definition had the results found in Google's favour?
