On April 1, Google updated the Video publisher policy, which was applicable to AdSense and Ad Manager, to apply to all video inventory including AdMob, under the Google Publisher Policies.

This expansion of coverage is intended to streamline the policies across Google products, as well as to keep pace with current industry standards.

Google tools associated to above change

  • AdMob
  • AdSense 
  • AdManager
The changes will be applicable to all the video inventory monetized with google ad code in Adsense and Admanager including AdMob under the Google Publisher Policies.

Accurately describe inventory

Video Inventory must provide declarations with correct video  signals (for Ad Manager, see VAST ad tag URL parameters), including:
  • Audibility of ad placement
  • Type of ad placement: "In-stream" or "Accompanying Content"

Use supported implementations

In-stream or Accompanying Content placements must use the Google Interactive Media Ads SDK or Google Programmatic Access Library on supported platforms, unless through an official Google Beta program.

Video ads serving into non-video player placements do not require declarations, and will be automatically determined by Google based on inventory format as either "Interstitial" or "Standalone" placements.

Value for advertisers

Video Inventory content or events (eg- play, pause, mute, skip, or dismiss), including ad content or controls where provided, must not be obstructed, hidden, or non-functional.

For In-stream placements, audio ads should not serve in the placements that are mute

User value

  1. Video Inventory may autoplay, provided that:
    • Only one Video Inventory across all placement types may autoplay with sound at any time.
    • Additionally for In-stream or Accompanying Content placements, only one video player may autoplay in view at any time.
    • The ad must not autoplay until at least 50% of the ad unit is visible.
  2. Video Inventory may be sticky, provided that:
    • A clear close (dismiss option is available for the user)
    • For In-stream or Accompanying Content placements, the video player must start in the main content and only transition to a sticky placement once the user scrolls the video player off the page.

Additionally for Ad Manager, the terms "instream" or "in-stream" in Help Center pages and in-product controls refer to both "In-stream" and "Accompanying Content" as defined in the updated Policies. Ad Manager Video Inventory that are "In-stream" or "Accompanying Content" per the updated Policies must adhere to the respective requirements in the Policies.
