A Pew study found that users of search engines were pleased with the quality of search results but opposed targeted advertising and search results, and were generally anxious about the collection of personal information by search engines. Specifically, 73 percent of those surveyed were opposed to search engines tracking their searches, and 68 percent opposed behavioral advertising. 83 percent of respondents reported using Google to conduct searches. Recently, Google began combining user data gathered from more than sixty Google products and services—including Google search--to create a single, comprehensive profile for each user.
