It lets you track clicks on links that point to external domains and accordingly sends Google Analytics events. This recipe will help you better understand what traffic you’re driving to other sites. No additional setup is needed.
INSTRUCTIONS
- Download Container File
Download the container JSON file (right-click on the link and click “Save Link As” or “Save Target As” to save the JSON file to your computer). - Import JSON File into GTM
Log into your own Google Tag Manager container and head to the Admin section of the site. Under Container options, select Import Container. Read this blog post for more details about importing a container file. - Update With Your Own Tracking ID
Update or create a new Constant Variable named {{YOUR_GA_TRACKING_ID}} with your Google Analytics Tracking ID (a.k.a. UA Number). I’d recommend using Google Analytics Settings variable instead. Read this guide how to properly change Tracking ID in the imported container. - Preview & Publish Google Tag Manager container
Use the Preview and Debug mode to test this container on your own site. Try testing each of the events to make sure they’re working properly. If everything looks good, go ahead and publish!
