Geo-Target Cookie Banners to Show Only What the Law Requires

A developer guide explains how to detect a visitor's jurisdiction from their IP and serve the appropriate cookie consent experience: strict opt-in for Europe, opt-out for the US, and none where not required. The approach uses IP geolocation to route visitors to one of three consent flows, with a fallback to opt-in when location is uncertain. The article notes that IP-based detection is probabilistic and fails with VPNs, so the safe default is to show consent when unsure.
