Google Analytics - Firewall
I have been experimenting with this, and are building up some data.
Unfortunately the Firewall is blocking this due to privacy so its throwing my numbers out. Need to take a look.
Domain Analysis: www.googletagmanager.com
Domain overview
www.googletagmanager.com is the primary content delivery endpoint for Google Tag Manager’s JavaScript container (gtm.js). When you install Tag Manager on a web page, the snippet references this domain to fetch your container configuration and any associated tag scripts.
Association with Google Analytics
Yes. Google Tag Manager (GTM) is often used as the deployment mechanism for Google Analytics (both Universal Analytics and Google Analytics 4). Rather than hard-coding the Analytics library directly on each page, you configure a “Google Analytics” or “GA4 Configuration” tag within GTM. At runtime, GTM loads the appropriate analytics library (gtag.js or analytics.js) from www.googletagmanager.com and initializes it with your Measurement ID or Tracking ID.
How the integration works
- Page snippet loads GTM’s gtm.js
The basic Tag Manager snippet you add to your site points to www.googletagmanager.com/gtm.js, which delivers your container’s tag definitions. - Tag configuration in GTM
In the GTM interface, you create a “Google Analytics: GA4 Configuration” tag, supplying your Measurement ID (G-XXXXXXXXXX). - GTM publishes and serves analytics code
When visitors load your page, GTM’s container script pulls gtag.js from www.googletagmanager.com, declares your global parameters, sets Analytics cookies, and fires pageview or event calls based on your triggers. - Data flows to Google Analytics
The injected gtag.js library sends collected data (pageviews, events, user properties) directly to your Analytics property in Google’s servers.
Key benefits of using GTM for Analytics
- Centralized tag management
- Version control and workspace previews
- Non-developer tag deployment
- Ability to layer additional tags (Ads, Floodlight) alongside Analytics
Additional considerations
- For auditability, inspect network calls to www.googletagmanager.com/gtm.js and gtag.js to verify container versions and loaded tags.
- You can enforce consent mode or custom parameters at the GTM level before firing Analytics tags.
- All configuration changes in GTM generate a new version, providing an auditable history of tag deployments.
If you’re evaluating containers for runtime footprint or compliance, you can run GTM in a sandboxed environment with verbose logging enabled, then monitor calls to googletagmanager.com and cross-reference with your internal audit requirements.
Thankyou No idea why people are still using search engine's. AI is much quicker.
