Can Webflow be used to enable GA4 tracking of YouTube videos via GTM without reloading the videos and inserting tracking support elements?

Yes, Webflow can be used to enable GA4 tracking of YouTube videos via Google Tag Manager (GTM) without reloading the videos or inserting tracking support elements directly into the videos.

To accomplish this, you can leverage GTM to listen for video events triggered by the YouTube API and then send the appropriate tracking data to Google Analytics 4 (GA4). Here's a high-level overview of the steps involved:

1. Set up Google Analytics 4 for your Webflow site:
- Create a new Google Analytics 4 property and obtain your measurement ID.
- In your Webflow project settings, navigate to the "Custom Code" tab and add the GA4 global site tag (gtag.js) using your measurement ID.

2. Integrate Google Tag Manager with your Webflow site:
- Create a new GTM container and obtain your container ID.
- In your Webflow project settings, add the GTM container snippet to the "Custom Code" section.

3. Configure GTM to track YouTube video events:
- In GTM, create a new tag for YouTube video tracking.
- Use a YouTube Video trigger to fire the tag when specific events occur, such as when a video starts, pauses, or completes.
- Set up variables in GTM to capture relevant video data, such as video ID, title, duration, etc.

4. Send video event data to GA4:
- Inside the YouTube video tracking tag, configure the appropriate GA4 event(s) to send data to GA4.
- Utilize GTM's data layer to pass the captured variables as event parameters.
- Map the event parameters to corresponding GA4 event parameters (e.g., send video ID as "content_id").

5. Publish and test your GTM setup:
- Save and publish your GTM container changes.
- Test the implementation by playing, pausing, and completing various YouTube videos on your Webflow site.
- Verify that the appropriate video events are being sent to GA4 by checking the Realtime reporting in GA4 or reviewing the recorded events in the GA4 interface.

By following these steps and configuring GTM correctly, you can leverage Webflow to enable GA4 tracking of YouTube videos without modifying the video elements directly. This approach allows you to centrally manage the tracking setup and easily make changes in GTM without touching the video code in Webflow.
