  • 1.5MB* maximum
    *includes initial plus subsequent/polite loads.
  • Please allow 150 KB for the Masthead components added by Studio.
User-initiated Load Size:
  • The usage of YouTube videos is recommended (no size limit)
  • Up to 1.5 MB for images and assets (animation/interaction) and 10 MB for non-YouTube served MP4/WebM/Ogg video.
    • The load from user interaction with Google Maps component is not included in the limit.
All videos must be progressive load. Cannot be streaming.
CPU Usage: Must not exceed 40% of a user's CPU. Common causes of high CPU use are continued animation & heavy animation sequences.

Video/Animation

YouTube-hosted Video
  • Must allow embedding
  • 16:9 aspect ratio is recommended to ensure proper fit in the player
  • Videos must have a relevant title; misleading or incomplete titles may lead to video removal
Video
  • If video is used, both MP4, and either WebM or Ogg formats must be used to ensure compatibility across all major browsers.

Note: Embedded players must have a viewport that is at least 200px by 200px. We recommended 16:9 players be at least 400 pixels wide and 225 pixels tall in order to fully display all controls.

Autoplay Animation / Video Length:

Max 30 seconds

Autoplay Audio: No sound
Clicking 'Unmute' button turns the video into user-initiated.
User-initiated Video: Regardless of the video length, control buttons (mute/unmute and pause/play) are required, as well as an indicator of the video duration or elapsed status.
Except for the initial autoplay video, each video play must be user-initiated.
Actions on User Click:

All sound and animation must stop upon exit click.  Mastheads containing a text field cannot have the 'autofocus' attribute.

Actions on User Interaction (animation): Animation must stop within 30 seconds after the interaction with it has ended.

Attributes

Fallback All HTML5 ads must gracefully fallback to support basic HTML5 to ensure full functionality across all modern browsers. Flash fallback is not supported and Flash content is not permitted in HTML5 ads on YouTube.
Border and iFrame:

Must stay within iframe and have black border of at least 1 pixel.

  • The border is added automatically if the Masthead is not expandable.
Mouseover Policy:
  • Minor animation on mouseover for informational or navigational purposes is allowed.
  • Animation cannot be disruptive or detract from user experience or the overall site functionality.
  • No user-initiated sound on mouseover.
  • If user takes mouse off the ad, user initiated animation should stop within 1 second. If it’s a game-like functionality, game should pause (not revert).
  • For cross screen buys on tablets and mobile, interaction should depend on taps, drag actions, swipes, and other touch screen interaction methods
  • Any other minor animation for entertainment or engagement purposes requires Google approval prior to launching.
Close button: DoubleClick Studio "Close Ad X" component is required on the top right corner with a padding of 5-10 pixels.
"X Close Expanded" button must have a 5 pixel padding from top and left sides of expanded Masthead unit and must be functional immediately after expansion

  • We suggest that the back up image resemble, as closely as possible, the final end frame of the ad animation - taking into account the previously stated attributes to ensure consistency in the advertisers message and user experience.
