Step 02: Script Tag & Google Tag Manager Placement​

Add the following initialization code directly in the <head> of your website, preceding Google Tag Manager and GA4:

<!-- 1. Google Consent Mode v2 Default Denied State -->
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}

  gtag('consent', 'default', {
    'ad_storage': 'denied',
    'analytics_storage': 'denied',
    'ad_user_data': 'denied',
    'ad_personalization': 'denied',
    'wait_for_update': 500
  });
</script>

<!-- 2. Google Tag Manager Container -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXXXX');</script>

<!-- 3. Consent Shield AI Kernel -->
<script
  src="https://consentshieldai.com/shield.js"
  data-site-id="CS-LIVE-PROD"
  data-gcm-v2="true"
  async>
</script>

Step 03: Verification in Google Tag Assistant​

  1. Open Google Tag Assistant (tagassistant.google.com) and connect your target URL.
  2. Observe the initial Consent tab: verify all 4 keys show Denied under the Default column.
  3. Click "Accept All" on the Consent Shield banner.
  4. Verify a consent update event is fired with all keys transitioning to Granted.
