Google server-side tagging uses Google Tag Manager server containers to process tracking data on a cloud server instead of directly in the browser.

In this setup, a website sends events to a server endpoint controlled by the business. The server then forwards data to platforms like GA4 or Google Ads. This method improves data quality, privacy control, and website performance.

Google also recommends using a first-party domain for better cookie management. Server-side tagging is widely used by businesses preparing for browser privacy changes and cookie restrictions. Seers AI can help businesses combine consent management with Google server-side tagging for more compliant tracking.
