Google Tag Gateway (GTG): What it is and how it works with CookieHub

Table of contents

Google Tag Gateway (GTG) is Google's recommended approach for serving Google Tags through a website's first-party infrastructure. Depending on the implementation, GTG can be deployed using supported CDNs, load balancers, or custom infrastructure.

As part of Google's evolving Consent Mode and CMP requirements, website owners may encounter GTG when configuring Google Analytics, Google Ads, or Google Tag Manager.

Does CookieHub support Google Tag Gateway?

Yes.

CookieHub is fully compatible with Google Tag Gateway deployments and supports Google Consent Mode, Google Tag Manager, and Google's latest CMP requirements.

Why GTG matters

GTG can change how Google Tags are loaded and initialized on a website.

Because Google Consent Mode relies on consent information being available before Google Tags begin processing measurement activity, deployment architecture can affect how consent signals are applied.

Incorrect deployment order may result in late consent signals being reported by Google.

Recommended deployment patterns

CookieHub supports several GTG deployment approaches. In most cases, we recommend managing CookieHub and Google Tags through Google Tag Manager to ensure consent defaults are established before measurement begins.

Deployment requirements may vary depending on the CDN or infrastructure provider used for GTG.

Detecting deployment issues

CookieHub continuously evaluates Consent Mode implementations and can identify situations that may result in late consent signals.

Potential issues are surfaced through:

Action Center warnings

Website scan reports

Consent Mode diagnostics
