Implement Google Analytics

[CrocoDillon]

Article might be outdated but something like https://www.themarketingtechnologist.co/setting-up-a-cookie-law-compliant-google-analytics-tracker/

So we don't need to bother users with a cookie notification.

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-38025571-3"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-38025571-3');
</script>

Need to figure out how to use with SPAs (I can imagine that needs some extra work to register page loads).

EDIT Doesn't seem to be that hard: https://developers.google.com/analytics/devguides/collection/gtagjs/single-page-applications
