It’s not about IP addr; I live in Sweden but don’t speak much Swedish. Searching for things takes me to Swedish sites.

Quite frustrating honestly.

(Another related thing that’s frustrating is people using my IP to determine language instead of the Accept-Language header my browser sends)

not OP, I live in Germany and 2 things happen with Geo-IP:

1. When I look for English words on Google, it prioritizes german dictionaries, sometimes for many pages instead of a) English dictionaries OR b) actual English pages relevant for that word

2. When I search for programming stuff, it prioritizes german pages, such as blog entries to the english documentation/english blog entries, which I find in any case more complete and diverse. Some peope prefer reading everything in German, but that is just not my cup of tea

can't remember I've ever searched for "restaurants near me" instead of using a map app or a self-choosen identifier. (And given e.g. Google Maps (on web) doesn't even reliably get the state right for my initial position, why would I rely on geoIP for that?!)
