How to make your Google Analytics GDPR Compliant with UniConsent

Updated: Use Google Consent Mode and UniConsent API on 1st April 2021.

People are looking for how to make your Google Analytics compliant with GDPR. There are only three steps to make your sites with Google Analytics compliant with GDPR.

Google Analytics has integrated with TCF version 2 recently, so you can implement it with TCF V2 CMP to make it respecting user's GDPR consent and choices.

The first step

Install a certified EU IAB TCF CMP such as UniConsent CMP. UniConsent has started to support TCF version 2 since 2019. It is fast loading and not blocking your pages.

The second step

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.

The last step

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>
