If you already have a Google Tag Manager account set up, see the section below.
Google Tag Manager implementation requires a testing process. Optimizely recommends that you implement Tag Manager on your Sandbox site first and verify accurate tracking of user events before recreating the tracking on your Production site. You must complete the following steps twice: once for Sandbox and once for Production.
Default tags included in Optimizely’s template tag container
This article details a basic setup of Tag Manager and includes a template container with a set of tags that will help you get your Tag Manager site up and running. This section walks through the details of the tags included in that container and refers to the json file entitled Spire-ga4-container.json (the json file for Classic CMS is coming soon).
The Tags provided in the template container are designed to work for the B2B Analytics product. Changes to the CSS may affect the behavior of these tags and should be tested and/or reviewed by your implementation partner or someone knowledgeable about Google Analytics 4 (GA4) before being pushed to production.
