The results that are displayed with a person's search done using Google, may differ depending on which PC he or she uses, the geographical location in which it is located and the frequency with which that computer is used by that same person. This is not a novelty, many have probably already noticed it because for some years numerous factors allow, automatically and without the knowledge of the user, to customize the searches.
In another article we said that any website retains the browsing and history data of those who visit it by storing its access on their computer.
Google, the most viewed site in the world, uses this technique very strongly to influence the results of searches and direct each user to the sites that he thinks are best for that person.
The factors why the results of the same search change are:
Google data centers
The different data centers that act as servers to allow this search engine to always be online, are located all over the world and are balanced so that they have the same data load in order to prevent one of them from overloading and going haywire.
Data centers are updated with new search algorithms and some of them may be based on the old algorithm, while others already use the new algorithm to display data.
The location of the world data center can also play a role in the search results that are displayed.
The geographical location of the user looking for
It is also important to note that Google tries to serve specific results for each country so that sites in Italian are displayed on Google.it or that they are specifically and explicitly aimed at the Italian public.
The history of the sites visited for a user with an Account .
Users who register and connect with a Google Account, Reader, Blogger, Gmail or any other Google-owned application, when using the search engine see different results than they would see if they had not logged in to that account.
Google in fact monitors the use of the search engine for registered users and shows results influenced by previous searches.
This therefore means that you can see completely different search results whether you log in with a Google Account or not.
Recent searches .
Google can change search results based on searches done by a user in a 30 minute period and this feature is called recent searches.
Even if you do not log in to a Google account, searches are stored in a cookie for about 30 minutes so that, while using the PC on the internet, the searches made are stored.
These recent searches can then be used to create customized search results pages.
Closing the web browser or manually deleting cookies will empty this temporary storage.
On rare occasions, recent searches can be kept on the browser for a different time duration, and this occurs during Google's experiments aimed at improving quality.
However, recent searches are not kept in the browser for more than 24 hours.
So this is good or bad "> Google Custom, a version of the engine without news, images and videos and without tracking cookies.
Otherwise you can use the browser in invisible or anonymous mode or, as Chrome writes, "incognito".
In this way cookies are not loaded nor are they stored, therefore the search does not take into account the memory.
For those who feel threatened in privacy I would just like to say that, in general, on the internet these days, for me, privacy no longer exists; the key word of the modern web is sharing and to fully enjoy the potential offered for free, hiding on the net becomes a big limit.
