Swap existing gtags on data.gov and resources with GTM container

tdlowden commented 2 months ago

User Story

In order to better track analytics, datagov team wants GTM implemented across the main datagov sites, for easier control and flexibility.

Acceptance Criteria

[ ] GIVEN GTM offers more flexibility in adjusting tags and sending events to GA WHEN resources.data.gov or data.gov is visited THEN Google Tag Manager should serve the gtag, rather than it being directly in the HTML

Background

GTM is already implemented on catalog.data.gov, and managing outbound linksand referrals across subdomains is easier in GTM if it is applied across all journey path subdomains

Security Considerations (required)

Limiting GTM admin access to datagov team members will ensure no extra security risk

Sketch

[ ] Remove existing G-WP7FK9QXZD gtag from <head> of both data.gov and resources.data.gov

[ ] Add in GTM container:

in the <head>, add:

<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-WZJC8CX7');</script>
<!-- End Google Tag Manager -->

directly after the <body>, add:

<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-WZJC8CX7"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->

Please coordinate with @tdlowden before this gets merged so we can simultaneously fire a new GA tag from GTM. Otherwise, there will be a gap in analytics collected
