If your site uses Google Tag Manager (GTM), you can easily add Click Guardian’s tracking code without modifying your site’s core files.
To install:
Open GTM and go to Tags > New
Select Custom HTML under Tag Configuration
Paste in the entire Click Guardian tracking snippet
Choose a trigger such as All Pages
Save and publish your changes
This method will automatically add the tracking code to every page GTM runs on.
