Hi @sysph ,

I will address each of your questions in order:

Q1: Can we link GA4 to one BigQuery project and then link Firebase to another project (app project)? Any pros and cons?

Yes, it's possible to link GA4 to one BigQuery project and then link Firebase to another project (your app project). This setup might be used for organizational reasons, billing separation, or access control.

Pros:

  • Separation of Concerns: Different projects can be used for different purposes, such as one for analytics and another for app development, which helps in managing access and permissions more effectively.
  • Billing Management: By separating projects, you can more easily track and manage costs associated with BigQuery usage and Firebase services.

Cons:

  • Complexity in Data Management: Having your data in different projects can complicate data management and integration tasks. For example, if you want to join Firebase data with GA4 data in BigQuery for comprehensive analysis, you'll have to manage cross-project data access and permissions.
  • Potential for Increased Costs: While separating projects can help with billing management, it might also lead to increased costs if data needs to be replicated or accessed across projects, especially if you're transferring large amounts of data frequently.

 

Q2: Creating remarketing segments - GA4 / Firebase?

In GA4, you can create remarketing segments directly in the GA4 interface or by using the audience features in Firebase if you're focusing on app users. These segments can then be used for remarketing campaigns in Google Ads or other platforms that support GA4 or Firebase audiences.

GA4: Use the "Audiences" feature to create segments based on user behavior, demographics, and other criteria. These audiences can be published to Google Ads for remarketing.

Firebase: Firebase allows you to create audiences based on events and user properties. These audiences can be used for targeting in Firebase Cloud Messaging (FCM), A/B testing, and can also be linked to GA4 for further analysis and remarketing.

Q3: How to tag app campaigns (Firebase)?

For tagging app campaigns in Firebase, you typically use UTM parameters to track the performance of your marketing campaigns. When you link Firebase with GA4, you can analyze the effectiveness of these campaigns directly in GA4.

  • Use UTM Parameters: Tag your campaign URLs with UTM parameters (utm_source, utm_medium, utm_campaign, etc.) to track where your traffic is coming from and how it's performing.
  • Firebase Dynamic Links: For mobile apps, Firebase Dynamic Links can be used to deep link users to specific content within your app and carry the UTM parameters for tracking.
  • Integration with Ad Platforms: Ensure your campaigns on platforms like Google Ads are properly linked and tagged to be tracked in Firebase and GA4.

Best Practices:

  • Consistently use UTM parameters across your campaigns for accurate tracking.
  • Monitor campaign performance in GA4 and Firebase to optimize your marketing efforts.
  • Leverage Firebase's ability to track app-specific events and conversions in conjunction with GA4's advanced analytics features.
