GoogleTagManager.liquid

Purpose

GoogleTagManager.liquid contains the theme's Google Analytics (gtag) integration and consent handling.

It is responsible for:

defining window.dataLayer

defining the gtag(...) function

setting a default consent state (denied)

loading gtag.js when GlobalData.Settings.googleAnalytics is configured

updating consent state based on the Cookie Manager configuration and the user's cookie preferences

Where it's used

GoogleTagManager.liquid is rendered by the main layout:

Structure/LayoutA.liquid

Example:

{% render 'Structure\\GoogleTagManager' %}

Inputs / data sources

Google Analytics id

GlobalData.Settings.googleAnalytics

When present, the template loads:

https://www.googletagmanager.com/gtag/js?id=...

The script reads the cookie:

_shopranos

and uses it to detect:

selected categories (e.g. analytics, advertising)

a stored consent version (prefixed as version-...)

The template attempts to locate a CookieManager component in footer components, then reads:

blocks with b.toggle.cookieCategory

cookie_manager.settings.consentVersion

This is used to:

decide which categories are configurable

expire old consent when the version changes

Output

The template outputs <script> tags in the page head that:

initialize consent to denied

optionally load and configure GA

update consent to granted for allowed categories

It also outputs two placeholders:

<script type="text/plain" data-cookie-category="analytics"></script>

<script type="text/plain" data-cookie-category="advertising"></script>

Notes

Consent is updated only when consent has not expired and at least one category is allowed.

Keep this template in sync with Cookie Manager behavior so categories and versioning stay consistent.
