1. Personalization without user identity
Published: 2026-09-29 17:01
Summary:
By grouping nearby users into buckets and aggregating their collective signals, we can construct rich, location-aware features available immediately for any user whose IP can be geo-located — no login, no prior history, and no persistent user identifier required.The challenge: serving users without individual signalsPersonalization at Airbnb has historically relied heavily on a user’s identifier to link together past searches, bookings, and browsing patterns This pattern holds however much Airbnb does or doesn’t know about the individual user.From any user’s IP address, the system derives a coarse geographic location, groups nearby users into an adaptive proximity bucket, and aggregates their collective signals into features for model scoring, with no persistent user identifier required.We operationalize this insight through a proximity key: a compact group key representing a local geographic cluster of approximately 1,000 users By grouping users geographically and aggregating their collective signals, we can construct features immediately available for any user whose IP can be geo-located, without relying on persistent user identifiers
