The integration of tags on your site, for example, tags for tracking or marketing optimization can be easily integrated and updated via the Google Tag Manager. With the simple user interface of Google Tag Manager, Google Analytics, AdWords and third-party tags could be add and update, without changing the code of the website.
With our Simple Google Tag Manager (GTM) integration extension you can integrate Google Tag Manager ID in a very short time into your shop.
