GTM + GA4: How to Track Videos on a Website

Youtube video tracking with GTM trigger and GA4

1. Disable Video Engagement tracking features in Enhanced Measurement.
   Otherwise, there's a high risk of occasional duplicate data.

   How to disable Video Engagement tracking in GA4:
   GA4 Admin > Data Streams > Gear Icon > disable Video Engagement tracking. 
   

2. GTM > Create a Youtube Video trigger
   
   Put the details as you see it above and then hit > SAVE

3. GTM > Enable built-in video variables
   GTM > Variables > Configure > Select all variables that refer to videos
   

4. GTM > Create a GA4 tag
   GTM >Tags > New > GA4 Event Tag as you see it below
   
   Don't forget to SAVE

5. Test the setup in debug view

   1. Go to your website and find a page that contains a Youtube player, for example https://www.eskimi.com/about-us
      Then go back to GTM, refresh, select Preview and paste the link of the website.
      Choose CONNECT.
      Then, you will see that a new tab will open. Activate the video (in order to trigger the events that we just created).
      

      Go back to GTM and see that the tag is fired :D 
      

   2. GA4 > Debug view
      GA4 > Configure > DebugView > see the events
      Also, don't forget to add the events in the Custom Dimensions [in order to be able to add these dimensions into your reports (Explorations)]
