Description

Automatically tracks interactions with embedded Wistia videos on your site.

This recipe will fire events to Google Analytics when users Play, Pause, Watch to End, and view 10, 25, 50, 75, and 90% of the video.

Scroll down to the full documentation for more information about customizing this recipe.

Instructions

1. Download Container File

Download the container JSON file.

(You may need to right-click on the link and choose “Save Link As” or “Save Target As” to save the JSON file to your computer.)

2. Import JSON File into GTM

Log into your own Google Tag Manager container and head to the Admin section of the site. Under Container options, select Import Container. Check out this blog post for more details about importing a container file.

3. Update With Your Own Tracking ID

Update or create a new Constant Variable named {{YOUR_GA_TRACKING_ID}} with your Google Analytics Tracking ID (a.k.a. UA Number).

4. Preview & Publish

Use the Preview options to test this container on your own site. Try testing each of the events to make sure they’re working properly. If everything looks good, go ahead and publish!

Optional - Customize How Frequently Events Fire

Currently, the following items are tracked to Google Analytics: Play, Pause, Watch to End, and view 10, 25, 50, 75, 90, and 100% of the video.

Documentation

Wistia Google Analytics & GTM Plugin

This is a plug-and-play tracking solution for tracking user interaction with Wistia videos in Google Analytics. It will detect if GTM, Universal Analytics, or Classic Analytics is installed on the page, in that order, and use the first syntax it matches unless configured otherwise. It include support for delivering hits directly to Universal or Classic Google Analytics, or for pushing Data Layer events to be used by Google Tag Manager.

Once installed, the plugin will fire events with the following settings:

  • Event Category: Videos
  • Event Action: <Action, e.g. Play, Pause>
  • Event Label: <URL of the video>

It will automatically bind to all videos on the page, even those added inserted dynamically after DOM Ready.

Installation

Universal or Classic Google Analytics Installation:

The plugin is designed to be plug-and-play. By default, the plugin will try and detect if you have Google Tag Manager, Universal Analytics, or Classic Google Analytics, and use the appropriate syntax for the event. If you are not using Google Tag Manager to fire your Google Analytics code, store the plugin on your server and include the lunametrics-wistia.gtm.js script file somewhere on the page.

<script src="/somewhere-on-your-server/lunametrics-wistia.gtm.js"></script>

Google Tag Manager Installation

Container Import (recommended)

  1. Download the file ‘luna-wistia-tracking.json’ from this repository.
  2. In Google Tag Manager, navigate to the Admin tab.
  3. Under the Container column, select Import Container.
  4. Click Choose Container File and select the ‘luna-wistia-tracking.json’ file you downloaded.
  5. Select Merge from the radio selector beneath the Choose Container File button.
  6. Select Rename from the radio selector that appears beneath the Merge selector.
  7. Click Continue, then Confirm.
  8. Navigate to the Tags interface – select the tag imported tag named GA – Event – Wistia Tracking.
  9. Change the {{YOUR_GA_TRACKING_ID}} in the Tracking ID field to your Google Analytics Tracking ID (a.k.a. UA Number).

Once you publish your next container, Wistia tracking will begin working immediately.

NOTE: If you’re using a custom GA cookie name, GA cookie domain, or GA function name, you’ll need to change those variables as well.

Manual Installation (not recommended)

Create a new Custom HTML tag and paste in the below:

<script type="text/javascript" id="gtm-wistia-tracking">
  // script file contents go here
</script>

In the space between the <script> and </script> tags, paste in the contents of the lunametrics-wistia.gtm.js script, found here. Set the Firing Trigger to ‘All Pages’. If you’d prefer to fire the tag only when a Wistia video is detected, create the following variable:

Set the ‘All Pages’ Trigger on this new tag. If you’d like to prevent a potentially unnecessary call to load Wistia’s API, you can customize your trigger to only fire when a Wistia video is detected on the page. Be aware that this might mess with tracking dynamically added videos.

Don’t forget, you need to add a Google Analytics Event tag that acts upon the pushes to the Data Layer the plugin executes. Follow the steps in the Google Tag Manager Configuration section for help on getting this set up.

Configuration

Default Configuration

By default, the script will attempt to fire events when users Play, Pause, Watch to End, and watch 10%, 25%, 50%, 75%, and 90% of each video on the page it is loaded into. These defaults can be adjusted by modifying the object passed as the third argument to the script, at the bottom.

Player Interaction Events

By default, the script will fire events when users interact with the player by:

  • Playing
  • Pausing
  • Watching to the end

To change which events are fired, edit the events property of the configuration at the end of the script. For example, if you’d like to not fire these events:

( function( document, window, config ) {

   // ... the tracking code

} )( document, window, {
  'events': {
    'Play': false,
    'Pause': false,
    'Watch to End': false,
  }
} );

The available events are Play, Pause, and Watch to End.

Percentage Viewed Events

By default, the script will track 10%, 25%, 50%, 75%, and 90% view completion. You can adjust this by changing the percentages.each and percentages.every values. Percentages are checked after each second of playtime and are based on the actual percentage of the total video the user has watched.

percentages.each

For each number in the array passed to this configuration, a percentage viewed event will fire.

( function( document, window, config ) {

   // ... the tracking code

} )( document, window, {
  'percentages': {
    'every': [25]  // Tracks every 25% viewed
  }
} );

percentages.every

For every n%, where n is the value of percentages.every, a percentage viewed event will fire.

( function( document, window, config ) {

   // ... the tracking code

} )( document, window, {
  'percentages': {
    'each': [10, 90]  // Tracks when 10% of the video and 90% of the video has been viewed
  }
} );

NOTE: Google Analytics has a 500 hit per-session limitation, as well as a 20 hit window that replenishes at 2 hits per second. For that reason, it is HIGHLY INADVISABLE to track every 1% of video viewed.

Using A Custom Data Layer Name or GA Global Name

If you’re using a name for your dataLayer object other than ‘dataLayer’, you must configure the script to push the data into the correct place. Otherwise, it will try Universal Analytics directly, then Classic Analytics, and then fail silently.

	// Example: GTMs Data Layer was renamed from dataLayer to fooLayer
(function(document, window, config) {

   // ... the tracking code

})(document, window, {
		'syntax': {
			'type': 'gtm',
			'queueName': 'fooLayer'
		}
});

	console.log(window.fooLayer);  
	> [{ event: 'wistiaTrack', 'attributes': { ... } }, ...]

	// Example: GA Global was renamed from 'ga' to 'fooTracker'
(function(document, window, config) {

   // ... the tracking code

})(document, window, {
		// For Universal Analytics Global
		'syntax': {
			'type': 'ua',
			'queueName': 'fooTracker'
		}
});

	console.log(window.fooTracker.q);  
	> ['send', 'event', 'Videos', ...]

Google Tag Manager Configuration

Once you’ve added the script to your container (see Google Tag Manager Installation), you must configure Google Tag Manager.

Create the following Variables:

  • Variable Name: DLV – Video Name

    • Variable Type: Data Layer Variable
    • Data Layer Variable Name: attributes.videoName
    • This will be the name of the video according to Wistia
  • Variable Name: DLV – Video Action

    • Variable Type: Data Layer Variable
    • Data Layer Variable Name: attributes.videoAction
    • This will be the action the user has taken, e.g. Play, Pause, or Watch to End

Create the following Trigger:

  • Trigger Name: Event – Wistia Tracking
    • Trigger Type: Custom Event
    • Event Name: wistiaTrack

Create your Google Analytics Event tag

  • Tag Name: GA – Event – Wistia Tracking
    • Tag Type: Google Analytics
    • Choose a Tag Type: Universal Analytics (or Classic Analytics, if you are still using that)
    • Tracking ID: <Enter in your Google Analytics tracking ID>
    • Track Type: Event
    • Category: Videos
    • Action: {{DLV – Video Action}}
    • Label: {{DLV – Video URL}}
    • Fire On: More
      • Choose from existing Triggers: Event – Wistia Tracking
