Asked on Oct 11, 2025
Answer
Tagging outbound affiliate links in Google Tag Manager (GTM) involves setting up a tag and trigger to track when users click these links. This helps you measure the effectiveness of your affiliate marketing efforts.
<!-- BEGIN COPY / PASTE -->
1. Create a new tag in GTM:- Tag Type: GA4 Event
- Event Name: "affiliate_click"
- Configure parameters: e.g., "link_url" with {{Click URL}}
2. Set up a trigger:- Trigger Type: Just Links
- Enable "Wait for Tags" and "Check Validation"
- Add a condition: Click URL matches regex (e.g., "affiliate.com")
3. Save the tag and trigger, then publish your container.
<!-- END COPY / PASTE -->Additional Comment:
- Ensure your GA4 property is connected to GTM by using the correct Measurement ID.
- Test the setup in GTM's Preview mode to confirm that clicks are tracked correctly.
- Consider using a regex pattern that matches all your affiliate domains.
- Review the event data in GA4 under Reports → Engagement → Events.
