Install Google Tag Manager

Optimizely Configured Commerce business users have the option to install either basic Google Analytics or a Google Tag Manager container on their various websites and domains by using three simple Website Settings. The steps to install Google Tag Manager are below.

Locate the Google Tag Manager container ID

Using the out-of-the-box Google Tag Manager implementation will allow you to provide the unique Google Tag Manager Container ID (often referred to as a "GTM ID") and the domains in which you want that tracker installed, and Configured Commerce will place the Google Tag Manager snippet with your provided GTM ID in the correct location across all pages on your site, as well as install the data layer for future use. If you are having trouble locating your container ID, see the Google Support article.
