Disable Google Web History
Google is changing its Privacy Policy therefore some people have decided that it is a good idea to disable their Google web search history which is stored for targeted ads and what ever else Google wants to store your searches for, here I will show you how you can turn this off in your settings.
Search History
Sooo. do you think this matters? if not then why not see what is in your history by following Google History you can see your search history that is stored with Google.
Opt Out
If after looking at your history you decide that you now want to opt out from Google auto storing of your history then you need to click the following link and select opt out (you will need to log in to your Google account) Google History Opt Out
Opting out just stops Google storing/collecting your search history and therefore also stops targeted search ads.. note: it does not delete your account just your search history..
Privacy Policy
I suggest you read Google's new Privacy Policy here as it comes in to effect on March 1, 2012.
