There is actually several ways around the tracking without using DuckDuckGo or GoodGopher.com

1.) The Safest Way (and most memory consuming)
Open a browser (like Firefox) to do the searching and have a different browser (like Google Chrome) to check your email and other internet activity. When you are done using the first browser to do your searching close it afterwards and leave the other browser up for your main internet activities.

If you need to do another search open up the first browser for just this purpose.

2.) The MOST inefficient way.
The other way is to disable all cookies on your browser and never log into your email accounts including Facebook while using your major search engines like Googles and Yahoo for searches.

You also must NOT log into your email or Facebook account until you close the browser and reopen it again to check your email or logging into Facebook.
