Installation

1. Create a site

Sign in to the admin and create a site. You'll get a unique slug.

2. Paste one line above GTM

Put this in the <head> of the client's site, above any GTM orgtag snippet:

<script src="https://your-domain.com/cb/loader.js?slug=CLIENT_SLUG"></script>

3. Block non-essential scripts

Swap type="text/javascript" for type="text/plain" and add a category attribute:

<script type="text/plain" data-consent-category="marketing"
        src="https://example.com/pixel.js"></script>

Categories: necessary · functional · analytics · marketing.

4. Google Consent Mode v2

The loader fires gtag('consent','default', …) synchronously before GTM boots, andgtag('consent','update', …) on every decision. All 7 signals are sent. No extra GTM configuration is needed on Google tags — their built-in Consent Settings handle gating automatically.
