"Google's latest updates to its terms of service have left many privacy advocates crying foul. One new feature called \"shared endorsements\" allows your name and photograph to be used in targeted advertisements on Google property sites.\nGoogle's support page for shared endorsements claims the feature will allow for more friend-based recommendation of music and restaurants, working much like Facebook's Sponsored Stories. \nSee also: The Beginner's Guide to Google+\nShared endorsements are not unique. Many sites, apps and browsers are using your information in ways you might not entirely comply with if you'd take the time to read their privacy policies. Often, opting out is only a click away, though it may be difficult to find out where exactly to click.\nWe've compiled this list of ways various Internet companies are tracking and using your data \u2014 plus, given you the tools to opt out, if you wish.\nTargeted Advertisements\nThe privacy policies of some sites allow them to turn your Likes and reviews into personalized advertisements.

While this web personalization might make for more finely-tuned results, it could also lead to slightly warped search results, depending what your search engine's algorithm has determined to be your interests.\nThe three major search engines all allow you to turn this personalized filtering off with relative ease.\n1.
