Learn about Google Analytics 4 (GA4) and how to connect your GA4 to Similarweb and access your data.

What is Google Analytics 4 (GA4)?

Google Analytics 4 (GA4) is the latest version of Google Analytics. It offers an enhanced approach to tracking and analyzing user data across websites and apps. GA4 focuses on privacy, machine learning, and cross-device user journeys.

What’s changing in Google Analytics?

GA4 introduces a new data model based on event tracking, unlike Universal Analytics (UA) which relies on sessions and page views. GA4 offers enhanced tracking capabilities, including event-based data collection, cross-platform and cross-device tracking, and a stronger focus on user engagement. It also provides advanced reporting and analysis features.

Why should I connect my site's GA4 to Similarweb?

Website owners can connect their Google Analytics account to Similarweb and share website data. Making this connection allows you to:

  • Benchmark your performance: Connecting your GA4 account privately gives you and your team a comprehensive view of your website's performance. You can benchmark performance directly against your competitors using Similarweb.
  • Get verified by Similarweb: Connecting publicly is useful for publishers and media brands who want to display their verified traffic to potential advertisers and partners and demonstrate their audience reach and engagement metrics.

Connection Types:  There are two different kinds of GA connections:

  • Publicly: this option is available for all users, free and premium. Anyone who views your page in Similarweb will see this data, along with the verified stamps.
  • Privately: this option is available for Similarweb premium users and will show verified data only for users who have access to that account. Verified stamps will not be shown for a website that is verified privately; however, they will be visible to users on the same account as the original user who completed the private connection.
