Online privacy isn’t always an easy thing to understand—or to explain. When I recently joined the company, I was happy to learn that Google was continuing with the effort to make our privacy practices (and your choices) even clearer and more accessible. We are using YouTube to post videos that explain how, when, and why we collect information about searches, and how you can protect your privacy while using our search engine.

If you watched the first privacy video, you learned about some of the information we collect (IP addresses, cookies, and search queries) and how we use this information to improve your search experience as well as prevent against fraud and other abuses. We appreciated all of the feedback we got in response to the first video.

In response to your requests for more detailed information, in our second video we're offering a closer look at personalization and the privacy tools available when you choose to personalize your search. Personalization has been an area that raises concerns about privacy, and we want you to understand how we personalize search results while protecting your privacy.

As the video explains, search algorithms that are designed to take your personal preferences into account, including the things you search for and the sites you visit, have better odds of delivering useful results for you. So if you’ve been checking out sites about the Louvre and you search for [Paris], you’re more likely to get results about the French capital than the celebrity heiress. The privacy tools we’ve designed — such as “pause” and “remove” buttons — help put you in control of personalization.

So sit back, take a look, and then tell us what you think about this video (and the earlier one too). We look forward to hearing from you.
