If you've been to Google's homepage lately — and the chances you have are astronomical — you may have noticed a little announcement mentioning something about changes in Google's privacy policy. You then probably ignored it — but you shouldn't.

On March 1st, 2012, Google will implement a new, unified privacy policy. The new policy is retroactive, meaning it will affect any data Google has collected on you prior to that date, as well as any data it gathers afterward. The official Google Blog has more details on what the new privacy policy means. But what does all of this legal jargon mean practically? Basically, under the new policy, your Google Web History (all of your searches and the sites you clicked through to) can be combined with other data Google has gathered about you from other services — Gmail, Google+, etc.

Previously Google kept your search history separate, which means that its profile of you was less complete. If you'd like to keep your personal data a good distance away from Google, you'll need to delete your existing search history and prevent Google from using that history in the future.

The Electronic Frontier Foundation (EFF) has more details on why you might want to turn off Google's Web History feature.

Privacy policies are ubiquitous, yet often highly irrelevant to the typical user; in this case, however, a little time spent changing your settings can provide invaluable peace of mind knowing that Google can't exploit your personal tendencies for its own purposes. Convinced yet? Read on for our guide to locking down your web history.
