Disable Magento’s Native Google Analytics Tracking

If you have been using Magento’s native Google Analytics tracking feature (or Google Analytics tracking using another extension), this must be disabled now or your Google Analytics data will be duplicated and the metrics will be skewed.

If you are unsure, follow this process to check and disable Magento’s native Google Analytics tracking, or check any other extensions which might have it enabled.

  1. Log into your Magento Admin Panel
  2. Navigate to System > Google API which is under Sales in the left navigation
  3. Change Enable to “No”

Publish Google Tag Manager Workspace

Publish the Google Tag Manager Container by clicking the blue “Submit” in the top right corner of the Google Tag Manager screen.

Your Enhanced Ecommerce tracking is now live.
