Please guys help me to know about GPSR (Google Personalized Search Result).
gpsr means Global Positioning Satellite Receiver.
Google Personalized Search Results is a new feature of Google search in which Google will show results partially based on user's past search history.
For example, someone searching for "jaguar" will see results for the animal if they tend to search for information on animals, but will see results for the car if past searches centered on automotive information.
Here's official blogpost explaining as to how personalizes your results,
