Google Tag Manager Implementation

Commerce Growth lets you implement Criteo OneTag through Google Tag Manager in three ways:

• If your website already sends GA4 enhanced e-commerce data layer, choose the recommended path for a fast setup.

• If your website uses a custom or incomplete data layer (or none), choose the customized path and wire our tags to your existing triggers and variables without changing your site code.

• If you use Google Tag Manager and want a guided, automated setup, you can use TagOMatic. This is Criteo’s AI‑assisted tag wizard that connects to your GTM account, reads your existing tags, triggers, and variables, and builds the required Criteo OneTag events on top of your current configuration.

You can choose your method in the Google Tag Manager section under Events Tracking > Reconfigure Tags.

If you don’t have access to the platform, contact Customer Care. If you are a developer, ask your client to share the guides and container with you.
