Video analytics

Support

AMP video analytics gathers data about how users interact with videos in AMP documents. Only AMP video extensions which implement AMP's common video interface are supported. These are listed below:

^[1] Partial support means that all video analytics common variables are included, except for currentTime, duration, playedRangesJson, and playedTotal.

Video analytics triggers

Supported AMP video extensions issue various analytics events during their lifecycle. These events can be reported through the analytics configuration using video-* triggers.

See the AMP Analytics component for details on amp-analytics configuration.

Video play trigger ("on": "video-play")

The video-play trigger is fired when the video begins playing from a user clicking play or from autoplay beginning or resuming. Use these configurations to fire a request for this event.

"triggers": {
  "myVideoPlay": {
    "on": "video-play",
    "request": "event",
    "selector": "#myVideo",
    "videoSpec":
  },
}

Note: This event was initially mapped to the playing event emitted by video elements instead of the play event. This may lead to overcounting as those events are also emitted when playing was interrupted by network issues. While this bug has been fixed in general, individual video players may continue to use the playing event internally instead of the play event.

Video pause trigger ("on": "video-pause")

The video-pause trigger is fired when the video stops playing from a user clicking pause, from autoplay pausing, or from the video reaching the end. Use these configurations to fire a request for this event.

"triggers": {
  "myVideoPause": {
    "on": "video-pause",
    "request": "event",
    "selector": "#myVideo",
    "videoSpec":
  },
}

Video ended trigger ("on": "video-ended")

The video-ended trigger is fired when the video has reached the end of playback. Use these configurations to fire a request for this event.

"triggers": {
  "myVideoEnded": {
    "on": "video-ended",
    "request": "event",
    "selector": "#myVideo",
    "videoSpec":
  },
}

Video session trigger ("on": "video-session")

The video-session trigger is fired when a "video session" has ended. A video session starts when a video is played and ends when the video pauses, ends, or becomes invisible (optionally configurable). This trigger is configurable via the videoSpec. Configuration options include:

1. end-session-when-invisible

Ends the session when the video becomes invisible after scrolling out of the viewport.

2. exclude-autoplay

Excludes autoplaying videos from reporting.

"triggers": {
  "myVideoSession": {
    "on": "video-session",
    "request": "event",
    "selector": "#myVideo",
    "videoSpec":
  },
}

Video seconds played trigger ("on": "video-seconds-played")

The video-seconds-played trigger is fired every interval seconds when the video is playing. The video-seconds-played trigger requires interval to be set in the videoSpec. Use these configurations to fire a request for this event.

"triggers": {
  "myVideoSecondsPlayed": {
    "on": "video-seconds-played",
    "request": "event",
    "selector": "#myVideo",
    "videoSpec": {
      "interval": 10, /* required */
      /* other optional videoSpec properties */
    }
  },
}

Video percentage played trigger ("on": "video-percentage-played")

The video-percentage-played trigger is fired every percentages when the video is playing. The video-percentage-played trigger requires percentages to be set in the videoSpec. Use these configurations to fire a request for this event.

Percentages must be set in increments of 5% and must be over zero.

"triggers": {
  "myVideoPercentagePlayed": {
    "on": "video-percentage-played",
    "request": "event",
    "selector": "#myVideo",
    "videoSpec": {
      "percentages": [5, 25, 50, 75, 100], /* required */
      /* other optional videoSpec properties */
    }
  },
}

Ad Start trigger ("on": "video-ad-start")

The video-ad-start trigger is fired when an Ad starts playing.

"triggers": {
  "adStart": {
    "on": "video-ad-start",
    "request": "event",
    "selector": "#myVideo"
  },
}

Ad End trigger ("on": "video-ad-end"))

The video-ad-start trigger is fired when an Ad ends playing.

"triggers": {
  "adEnd": {
    "on": "video-ad-end",
    "request": "event",
    "selector": "#myVideo"
  },
}

Video spec

You can use the videoSpec configuration object to control how the requests are fired.

end-session-when-invisible

This spec property controls the video-session trigger. If true, the trigger will fire when the video is no longer visible, even if it is still playing. The default value is false.

exclude-autoplay

This spec property controls all video-* triggers. If true, the trigger will not fire for videos that are autoplaying when the triggering event occurs. If a user interacts with the video and causes autoplay to stop, video-* triggers configured with "exclude-autoplay": true will begin to fire for that video. The default value is false.

interval

This spec property controls the video-seconds-played trigger, and it is required for video-seconds-played.The value for interval specifies the number of seconds between each video-seconds-played event, and it must be greater than 0. For example, a value of 10 fires the trigger every 10 seconds when the video is playing.

Common variables

All video analytics triggers expose the following variables. These variables are also available in variable substitution with the VIDEO_STATE variable.

Click-to-play Events

Click events set directly on video component elements (like amp-video) will not be captured consistently due to implementation details of the browser's native video player or the player component itself.

You can capture independent play/pause events by using the video-play and video-pause triggers.

If you'd like to capture the initial play event (e.g. click-to-play), you can place an overlay on the video player and configure a click analytics request that refers to the overlay element (#myOverlay):

"triggers": {
  "video-clicked": {
    "on": "click",
    "request": "event",
    "selector": "#myOverlay"
  },
}

Video analytics variables

Video analytics contributes the following variables to AMP URL Variable Substitutions.

VIDEO_STATE

The VIDEO_STATE(selector,property) variable is substituted with the value of the selected video's specified property, as defined under Common variables above. The selector argument can be any valid CSS selector. The property argument can be the name of any of the common video analytics variables.
