Personalized search results
When the personalized search results setting is switched on it means that we can improve your search results based on your previous search history. To achieve this we pass an anonymous unique identifier to our search partner Bing.
The differences are generally quite subtle, but the more you search with this setting switched on, the more personalized the results will become.
Why would I want personalized search results?
Let’s say you enter the search term "Australia". Without any other context it is very hard for a search engine to serve you the most relevant results for your specific intent. You might be looking to plan a vacation, or maybe you’re a movie-buff and instead you’re searching for details regarding the movie Australia.
By having the personalized search results setting enabled, it will help us provide you with most relevant results.
How do I turn personalized search results off?
If you would prefer your search results not to be customized based on your past search activity, you can turn off personalized search results at any time in your settings.
