Why doesn’t Google turn off personalization?

Google’s personalized search has come a long way since its inception and has proven to do more good than harm for the average user’s experience. The introduction of machine learning algorithms and user behavior analysis allowed Google to refine search results based on more than just individual preferences. At its core, personalization is designed to enhance the search page by delivering more relevant and contextually appropriate information to users. Plenty of words carry many different meanings and Google’s software has gotten quite good at assuming which meaning a given user is looking for. Even when a user types a single word into the search bar, Google rarely returns results for a different meaning of the term.

Here’s an example: An adult searching for “Buffalo boats” while connecting to the internet in Buffalo New York will see a list of marine dealers near them, not barges made for transporting large animals, boats with pictures of a buffalo on them, or results from any of the 13 other states that have a town named Buffalo. From that two-word search term and the user’s physical location, Google is able to deduce what they’re actually shopping for.

Factors Influencing Personalized Search

a) Search History: Google takes each user’s past search queries and interactions into account to better understand their interests and preferences. The algorithm uses this information to tailor search results accordingly: If someone visits a specific website often, that website might be intentionally pushed down because Google has assumed they are searching for alternatives.

b) Location: Localized search results have become increasingly important as Google aims to provide users with information that is relevant to their specific geographic location. As a device travels across town, the results for any localized keywords will start to change.

c) Device and Context: Google considers the category of device being used (desktop/tablet/mobile) and the context of the search (such as time of day or recent events) to deliver more personalized results.

d) Social Connections: The newest iteration of the algorithm may also incorporate social signals from a user’s prior interactions, reviews, and even email history when determining search rankings.
