99 Club Studio analytics setup

The site contains a privacy-first Google Analytics 4 integration plus Studio-specific product events.

Activate GA4

Create a Google Analytics 4 property and Web data stream for https://99studio.uk.
Copy the Measurement ID in the form G-XXXXXXXXXX.
Put that value in assets/99club/analytics-config.js as ga4MeasurementId.
Deploy. The analytics choice UI appears only when a valid GA4 Measurement ID is configured.

The Google tag loads with Google Consent Mode. Analytics storage defaults to denied and is changed to granted only after the visitor chooses Allow analytics. Advertising-related consent/signals remain disabled.

Automatically available GA4 information

Once activated, GA4 provides the normal website analytics layer, including page views, users/sessions, traffic acquisition/referrers, device/browser information and approximate geographic reporting.
