How Does Google Maps Know A Business Is Busy?
bgr.com • • technology
Key Points:
- Google Maps provides a "Popular Times" feature that shows how busy a business is at different times, using aggregated and anonymized location data from users who have opted into Google Location History.
- The data is collected by measuring the density of phones in a given area over time, enabling Google to estimate visit duration, wait times, and real-time busyness without manual input.
- Google ensures user anonymity through differential privacy and only publishes busyness data when there is enough information to maintain accuracy and privacy.
- Beyond location data, Google collects extensive personal information such as payment details, search and browsing history, and purchase data, allowing it to track user behavior even when GPS is off.
- This comprehensive data collection helps Google provide accurate busyness estimates and insights into user visits, purchases, and reviews at businesses.
