Web sites now routinely ask consumers to provide personal information in exchange for access to premium content, free e-mail, contests and more. Consumers have responded to these requests by readily providing that information.
It's no exaggeration to say the Internet has evolved to the point where exchanging personal data for content and services has become a regular quid pro quo. What was previously accepted as gospel--that Web sites should not ask people for personal information because it will deter visitors--has given way to a more practical balance.
The user preference and demographic information needed for personalization is not very different from what is already being collected from consumers. So companies like Yahoo and Google need only collect the most basic information. But what constitutes this "basic" information?
To a large extent, it's the same as that required for free registration at many Web sites and includes details such as gender and geographic location. For best results, services also collect information regarding a consumer's preferences. This can include very specific information, such as which sports teams a consumer follows, preferred locations for vacation travel, or news topics of interest. It can also include more abstract information such as whether a consumer prefers aggressive electronic music with a driving beat or mellower acoustic music.
Safe, effective use of personalized search requires consumers to use common sense.
Search services themselves also share the burden of making personalized search safe for consumers. Services must continue to earn the trust that consumers place in them by ensuring that their information will be used exclusively to benefit the search experience and will not be shared with third parties for any reason.
In general, we as consumers have become desensitized to the information we give up because we're so used to providing it to the companies we patronize. It's not unique to the world of the Internet either. The fact is you can't buy batteries in a Radio Shack without being asked for personal information, including your name, phone number and ZIP code.
The search wars and the advent of personalized search are drawing attention both for their promise and for their potential pitfalls. Regardless of who emerges victorious, the use of personal information will continue to be at the forefront of technology innovation. As long as people are able to remain anonymous--and search services properly safeguard the information collected-?then supplying insight into who we are and what we prefer should not sound privacy alarm bells.
