It's easy to understand why privacy advocates and policymakers are sounding alarms about online privacy in general – and singling out Google in particular.
If you use Google's search engine, Google knows what you searched for as well as your activity on partner Web sites that use its ad services. Technically, of course, Google doesn't know anything about you. But it stores tremendous amounts of data about you and your activities on its servers, from the content you create to the searches you perform, the Web sites you visit and the ads you click.
The more Google knows about you, the more it can match you to an advertiser who thinks you are an ideal customer. Advertisers are willing to pay more for ads served to ideal potential customers. For instance, airlines want to target people who love to travel. Children's clothing makers want to target parents. Want to find out all the things Google knows about you?
