How To Disable Google’s Personalization Of Search Results
It’s never been a secret that Google uses your personal information (web history and browser data) by default to personalize your search results. Basically what it means is that what you see for some Google searches is (slightly) different from what other people see for the same searches.
You may like the feature (but want to switch it off for some searches) or you may want to disable it completely – it’s up to you and your purposes.
