Switch your old Google Analytics tags including https://www.google-analytics.com/analytics.js to the new tags

You can get this by visiting https://analytics.google.com/analytics/web/, then click "Admin" and "Tracking Info", "Tracking Code".

You can use either Global Site Tag (gtag.js) or by installing with Google Tag Manager.

Add the following code before your Google Analytics tags or your Google Tag Manager:

<script>
  window.dataLayer = window.dataLayer || []
  function gtag() {
    dataLayer.push(arguments)
  }
  gtag('consent', 'default', {
    ad_storage: 'denied',
    analytics_storage: 'denied',
  })

  __tcfapi('addEventListener', 2, function (tcData, success) {
    if (success && tcData.unicLoad === true) {
      gtag('consent', 'update', {
        ad_storage: 'granted',
        analytics_storage: 'granted',
      })
    }
  })
</script>
