Do you know every Google search you've ever performed is stored on
the search giant's servers? And that data is cross-linked to your search
data from YouTube, Google Maps and any other Google services you use.
that mountain of information, Google can tell a lot about you: where
you live, your hobbies, age, health problems, religion and more.
course, Google uses that data mostly to target you with ads. If you
spend 20 minutes doing research on a gadget, for the next few weeks
you'll probably be hounded by ads for that gadget wherever you go
Because search sites and other Web services have become so
ingrained in our daily digital lives, it isn't really an option to stop
However, you can keep a lower profile and put a
little more distance between your personal data and Google. To start,
you can clear out your Google search history.
To see what forgotten secrets lurk in your Google history, go to https://www.google.com/history and sign in with your Google account information. You'll see a list of everything you've ever searched for on Google.

Once your information is removed, click the gear icon in the
upper right corner of the page and choose Settings. Here you have the
option to turn off your Web history. This will stop Google from
recording anything else.

your information isn't really gone. Google will still keep your
"deleted" information for audits and other internal uses. However, it
won't use it for targeted ads or to customize your search results.
your Web history has been disabled for 18 months, the company will
partially anonymize the data so you won't be associated with it.
you don't have a Google account, or don't usually sign in to it, Google
still tracks your history. To accomplish this, it uses a cookie stored
in your browser.
You can wipe out the information by deleting the cookie, but Google will just start recording new information. Instead, you can opt out of interest-based ads altogether by going to http://www.google.com/settings/ads.
you're still concerned about stored information, your best bet might be
to avoid using Google Search as much as possible. Alternative search
sites DuckDuckGo and IxQuick parallel Google Search in features and performance, but don't collect any private information about you.
Microsoft's Bing Maps is a good replacement for Google Maps. Try using the venerable Firefox Web browser instead of Google's Chrome.
The more you mix and match Web services, the less any one company is able to form a complete picture of you.
forget that while you're busy surfing the Internet, your browser is
also busy making a list of the sites you visit. Anyone who gets access
to your computer can see it.
You can delete some or all of the
websites you've visited by going to your browser's options menu. Or you
can use a free third-party cleaner program like CCleaner.
you want to surf the Web without leaving a trace, all modern browsers

computer) can still track the sites you're visiting. Avoiding that
tracking requires an entirely different set of steps.
