Verification for Google Tag Manager Implementation

• Before deploying the tag live, use Google Tag Manager's preview mode to test whether the tag fires correctly when you interact with the video on your website.
  
  
• Publish: Once you've tested the tag and confirmed that it's working as expected, publish your changes in Google Tag Manager to make the tag live on your website.

By following these steps, every time someone watches a video on your website and the trigger conditions are met, a hit will be sent to the URL you specified behind the scenes.
