To use Google Analytics for cross-device tracking, you can follow these steps:
- Implement User-ID tracking: User-ID is a feature in Google Analytics that assigns a unique ID to each user, allowing you to track them across different devices. This requires some developer implementation to assign and store the User-ID for each user.
- Set up the User-ID view: In your Google Analytics account, create a new View specifically for User-ID tracking. This will help you isolate and analyze cross-device data separately.
- Enable User-ID in the tracking code: Modify your Google Analytics tracking code to include the User-ID feature. Use the ga('set', 'userId', 'USER_ID') method to pass the unique ID for each user.
- Ensure consistent User-ID assignment: Whenever a user logs in or visits your website/app on a different device, make sure the User-ID is assigned consistently across all devices. This ensures accurate tracking of the same user.
- Implement cross-domain tracking: If your website spans multiple domains, configure cross-domain tracking so that Google Analytics can recognize users navigating between these domains. This provides a more complete view of the user's journey across devices.
- Analyze cross-device reports: Once you have implemented User-ID tracking and collected sufficient data, you can analyze the cross-device behavior of your users in the User-ID view. Google Analytics provides reports like "Device Overlap" and "Device Paths" to gain insights into how users interact with your website on different devices.
