Summary Box: Google ranked highly despite privacy

THE CONCLUSION: Google is almost everyone’s favorite search engine, despite misgivings about data-collection and advertising practices that are widely seen as intrusive.

THE DETAILS: The Pew Internet & American Life Project found 83 percent of U.S. search engine users rated Google as their preferred search engine. That was up from 47 percent in 2004.

POTENTIAL TROUBLE: Google may be risking its popularity by trying to learn more about users in a quest to sell more advertising. Nearly three-fourths said they don’t want search engines to sift through their personal information to deliver results tailored to their individual interests.
