Google to use UK and EU user IP addresses for ad personalization
What happened
Google notified advertisers it will start using UK/EU/Swiss IP addresses for ad measurement and personalization, changing the legal status of routine network data. The announcement sets an effective window around early August and highlights that IPs will be used for device identification and personalization, which triggers consent requirements under regional law. Buyers should watch the technical methods Google publishes (hashed IPs, on‑device PETs) and get supplier processing commitments
Why the category manager should care
Ask suppliers for documented processing purpose, consent mechanics, and fallback measurement modes; do not assume existing DPAs cover this new purpose
Key facts
- Change applies to UK, EU, and Switzerland
- Planned start on or shortly after August 3
- IP addresses will be used for measurement and personalization
