Google Tag Manager allows the management of tags across a website without editing code.
It is possible to add a Google Tag Manager id to your store. Google tag manager will then be loaded on all pages across the store.
If used for tracking, re-targeting or analytics purposes please note that google tag manager will load regardless of the customers response to the cookies warning. This means customers will not have the opportunity to opt out of services integrated in this way.
Google Analytics and Facebook tracking should always be implemented using Ochres official integrations to take advantage of our events tracking integrations and for them to be reactive to customers the cookies warning responses. This can be found in Site Settings > Analytics and Tracking
