This search shows where all the older Analytics integrations are: https://github.com/search?q=org%3Aukwa+google-analytics&type=code

And this covers PyWB https://github.com/ukwa/ukwa-pywb/issues/86 (which uses a slightly newer version of the analytics code)

BTW, in Google Analytics, I've set up a new http://www.webarchive.org.uk - GA4 'property' which we'll be able to move things to. It requires this tracking code:

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-K5N6D6LKHP"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'G-K5N6D6LKHP');
</script>

I've checked with the BL comms and web teams on how they are processing this transition. They plan to add GA4 in the autumn and run both systems together for 6 months (until the end of Mar 23) while they are setting up the new 'events' in GA4. I think we should do the same approach. This would ensure continuity of current stats until the end of the 2022 reporting period and give us time to set up a new system.

Thanks @jasonwebber-bl that makes sense. So we should just add the new tracking code, so that both are active, rather than replacing one with the other.

[jasonwebber-bl]

Yes please. Setting up the events in the new GA4 will need some thinking about. I'm currently trying to learn what the possibilities are and it would be good to be able to test and try some of these.

@min2ha it should just be a case of pasting and adding in the HTML fragment in https://github.com/ukwa/ukwa-ui/issues/349#issuecomment-1111030511 into the UKWA-UI codebase in the right place.

As this is a very small and simple change, I've asked @min2ha to include it in the 1.4.2 release.

Logged into Google Analytics and I can verify that the visits are coming through for UKWA-UI.
