It seems like a good thing to do: look up you Social Security Number on Google to see if it is out there on some hacker site with your SSN listed, letting the bad guys steal your identity.
Don’t do it!
There are sites that have all 1 billion combinations of social security numbers listed, thousands to a page. These sites have been indexed by Google and other search engines. If you click on one it will pass the site the search string that you entered on the search engine. The website now knows that you searched for that number, so they know your social security number is good, and they put it up for sale. A short time later someone is taking out loans using your credentials.
DO NOT GOOGLE YOUR SOCIAL SECURITY NUMBER!!!!!!
