Why such a situation with the coordinates of the approximate location in the Google account?

Question

Google

Hello.
Please tell me about this "problem". Relatives have several Google accounts.
One account has a lot of "Based on your previous activity" tags in "App & Web Search History" (on a desktop browser). A person often uses mobile Internet (MTS).
Others more often use wi-fi in the same place and do not have such labels. Or almost none.
The problem (or not a problem, I don’t know) is that when a person of this account uses a working wi-fi, the approximate location is indicated relatively correctly (taking into account the calculation error for the operator’s base stations), namely the coordinates 47.547352,40.897365. Geographically, this is a village (just fill in Yandex maps).
Other accounts receive exactly the same coordinates if they connect to MTS mobile communications in the village itself.
Precise geolocation (by satellite) is disabled on all phones. It remains only indirect, on the towers of the mobile operator. So we take into account the error.
When a person leaves work and connects to the mobile Internet at home (also the same village), then, in most cases, in history he receives marks of an approximate position with coordinates 47.542610.40.799024 (less often 47.522822.40.806160). Percentage of 80 cases. This is plus or minus the same place, but located in a nearby town. The distance between the coordinates in the village and in the city is quite large (10 km).
The question is the following. Can you please tell me what are the conditions for such a situation? Should the condition of the frequent presence of the account holder in this nearest town be mandatory?
It is not possible to find out reliably his actual location at the moments when he uses the search and, accordingly, the “approximate location” is indicated in his account. The man claims that he has been at home all this time, in the village.
If to obtain such coordinates the subscriber must be regularly in the town, then how often? How long should he stay there in order to regularly receive the coordinates of this city, while being in his village?
Search queries are the most common and not very frequent (search for poetry, music, weather, etc.).
Just on other accounts, if they connect to the mobile Internet in the village, it shows the village.
Between these two coordinates there are several base stations of the cellular operator. In the village itself, on the opposite side from the city, in the neighboring village there is a base station (two or three kilometers away).

Thank you.

It is not possible to find out reliably his actual location at the moments when he uses the search and, accordingly, the “approximate location” is indicated in his account.

Perhaps he simply disables the "Location History" in the account:

Precise geolocation (by satellite) is disabled on all phones. It remains only indirect, on the towers of the mobile operator.

Google's geolocation does not work this way, it relies (in descending order of priority) on:
1. Geo-coordinates of Wi-Fi hotspots
Google collects the geo-coordinates of all Wi-Fi hotspots. It is enough to connect to it once from your mobile device with a GPS module, or someone will simply pass next to their mobile phone with Android (no need to connect) - data about this point with reference to geo-coordinates will be sent to Google:
- Wi -Fi is watching you
- Google has published a way to hide a WiFi hotspot from being used in its location services.
2. Base stations of cellular operators
On phones with Android OS, Google has the ability to directly access the radio module, measure the signal levels of the base stations of the OPSOS and accurately determine the geo-coordinates of the phone even with GPS turned off.
He regularly receives the geo-coordinates of these base stations (BS) from other Androids with GPS enabled, which connect to these BSs.
But on Apple devices, Google does not have access to the radio module (Apple itself collects data there for its own needs)
3. IP-address
Reserve inaccurate method. However, YouTube ads are still targeted by IP address.
The first two methods allow you to accurately determine your location even when your IP address is changed using a VPN. Therefore, for "region-dependent" search queries Google and Yandex (yes, he also does this) give answers based on your actual location.
Therefore, it is impossible to answer your question without additional information (and testing).
You can work via the MTS Internet, but your neighbor has turned on the WiFi hotspot on his mobile phone with GPS enabled. Google immediately determined that your device is in the "neighborhood" WiFi zone (you don't need to connect to it, you can see the available WiFi networks within range), and it learned your geo-coordinates for sure.

If to obtain such coordinates the subscriber must be regularly in the town, then how often?

No, Google does not show "most frequently visited", but your real location (how accurately it was able to determine it) at the moment the event was recorded.
PS: Big Brother is constantly watching you, using your own computer / phone for this.

Perhaps he simply disables the "Location History" in the account:

I have access to all accounts (they are mine, I just distributed the ones that my relatives already had when buying android phones). Everything is included in the account.
I just read that without turning on the GPS on the phone itself, there will only be an indirect "based on previous actions".
He doesn't have Wi-Fi at home. Neither do the neighbors. There are at work. Yes, when at work, he uses wi-fi and the approximate location is correct - the village. When he goes home, then more often these are the coordinates that he cited above, i.e. in a neighboring town 10 km.
I have been going to this city for the second day (I myself live in the same village). GPS is off, wi-fi is off, mobile communication is off. I come closer to those city coordinates, I turn on only mobile communications. And then I ride around the city, periodically making search queries. If an entry is made in chrome on an android phone, then it puts tags quite often, if not, then much less often.
Then I turn off the mobile connection, return home and look at the history (all tracking items are also included there). And all my city searches that have a location label have village coordinates. All without exception.
Although the superfluous was disabled, and included only in the city. And only mobile communications.
I rode for about an hour every day.
Therefore, I concluded that Google does not instantly show only mobile communications. Like, I mostly live in the village.
Hence the assumption that in this case you need to be in place with some regularity for this "Based on your previous actions" to work.
