One of the key arguements for collecting personal search histories is that a “perfect search engine” will use this personal information to deliver more relevant advertisements. The supposition is that the search engines benefit from selling a more detailed profile to marketers, marketers save money by presenting only relevant ads to interested users, and users aren’t bothered with irrelevant advertising.

With sharp advances in database marketing, the proliferation of data mining and the widespread adherence to principles associated with precision marketing, the logical expectation is that customer acquisition and retention rates would rise as direct marketers shift from mass marketing toward one-to-one marketing.
