Geo ip doesn't have that accuracy, right? Google use GPS.

https://support.google.com/google-ads/answer/2453995?hl=en "Device location: Depending on a user's location settings, we may be able to use a precise location for advertising, based on one of these sources of location data:

GPS: Accuracy varies depending on GPS signal and connection. Wi-Fi: Accuracy should be similar to the access range of a typical Wi-Fi router. Bluetooth: If Bluetooth and/or Bluetooth scanning are enabled on a device, a publicly broadcast Bluetooth signal can provide an accurate indication of location Google's cell ID (cell tower) location database: Used in the absence of Wi-Fi or GPS. Accuracy is dependent on how many cell towers are located within an area and available data, and some devices don't support cell ID location."

Google doesn't share device GPS. Ad location targeting is at the country, state, and city level, or in increments as small as 3 sq. km.

Geo IP data is accurate ~85% at the city level and ~99% at the state level, meaning they're approximately the same.
