I work in adtech and this is how we do geolocation. There's also device geolocation but if the user doesn't consent to sharing their GPS data with us, we just use IP address for targeting. Common provider for this is Maxmind; they ship a database that you host locally and query
Even the free maxmind db is accurate enough for most applications.
Does Cloudflare have the same data as Maxmind?
Because Cloudflare and Maxmind geolocate me to the exact same longitude/latitude.
CloudFlare uses Maxmind: https://developers.cloudflare.com/support/network/configurin...
Since you are in adtech: do you buy MaxMind, or roll your own? Are there any providers for US-only data, and therefore, cheaper?
We licensed Maxmind's DB recently (it's like $300 a year or something). idk if there are US-only databases. Our customers are all in the US, and we use geo IP to filter european users for compliance (GDPR and otherwise)
