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.
