Parents who continues to worry that their kids might still encounter sexually explicit web sites even when they have Google’s SafeSearch feature on can now rest easy. Google has just made SafeSearch safer with the introduction of a locking feature.
The lock feature brings SafeSearch to the stricktest level of filtering that Google can possibly provide to users, says a post from the Official Google Blog. To activate this feature, just visit the “search settings” and enter your password to turn the feature on.
Once activated, you’ll know that SafeSearch is locked if you see some colored balls on top of the page. Once this colored balls disappear, you’d know that you should turn on the lock again.
