First, if you are a die hard Google fan and cannot live without them, one thing you can do to reduce Google’s ability to collect information about you is to avoid being signed in when you do a Google search. In other words, once you have been to Google Plus, checked your Gmail, or spent time updating or referencing your online calendar, simply sign off from your account. That does not mean that Google won’t know what IP address is searching, but it might reduce the chances they will associate you with whatever your online activity is.
Another option is to simply utilize another search provider. Ixquick is a great option for those concerned about privacy. If you are using a browser that has a quick search toolbar, you can even add Ixquick to it and choose to search using it instead of Google, Bing, etc.
The point is you do have choices, even if Google tries to prevent you from having them. As of March 1, 2012, you won’t have a choice about letting Google store your personal information if you have a Google account. While their position is that it lets them provide better service to you, it is possible you just might not agree with that. And, if you do not agree, take the above steps or research other options. Perhaps you will find another search provider offers everything you need once you have given them a chance.
