Googling yourself is important because you never know what information about you could be floating around in cyberspace.

To
see what the Internet knows about you, start by going to the Google
site or by using the Google toolbar. Next, either type your name in
quotations or, for a more refined search, type intext: (intext with a
colon) immediately followed by your name in quotes. Now type your
address or phone number, and Google may turn up a church or a social
group directory listing. If this doesn’t surprise or outrage you, type
into Google your social security number or credit card numbers.

Instead of taking Google for granted, we need to keep in mind that criminals get the same easy access to information we get from a capable and quick search engine.

To prevent unscrupulous individuals from gaining access to confidential information about you, never put anything personal, such as your social security number on a
resume on the Internet, not even temporarily. And if you find such
information on a cached Web page (a page that has been taken off a live
site but still exists within Google, consult this page for more details.
